200 delegates from 34 countries attended Europe’s largest Annual Spectrum Summit, hosted by LS telcom in conjunction with PolicyTracker in Lichtenau / Baden.

Lichtenau / Baden, Germany, 4th July 2019 – “Spectrum for Everyone & Everything” was the theme of the 24th Annual Spectrum Summit concluding yesterday at LS telcom’s headquarters in Lichtenau, Baden-Wuerttemberg, Germany. The conference built upon the many 5G issues from last year’s event and took into consideration recent developments. The agenda featured presentations and panel discussions on new approaches for spectrum access for verticals, on the increasing amount of background noise on radio communication infrastructure and methods to mitigate the problem, as well as TV broadcasting via mobile networks.
The event attracted a variety of representatives and thought leaders from regulatory authorities, mobile and broadcast operators, industries, industry associations, spectrum consultants and research institutes.

The conference opened with a keynote by Harald Berninghaus, Deputy Head of Unit for Digital Society, Frequency Policy and Mobile Communications at the Federal Ministry of Transport and Digital Infrastructure, Germany, on the topic “Spectrum for the wireless age - the challenges ahead”.

In the many controversial debates, different stakeholders presented a diversity of 5G requirements as well as issues that need solving to make 5G available for “everyone & everything”.
“For the success of 5G in Industrial IoT, it is mandatory to have dedicated resources for wireless data communication since reliability in all aspects of operation is essential in the context of a factory or production plant,” explained, for example, Dr.-Ing. Christian Bauer, Lead Developer 5G at TRUMPF Werkzeugmaschinen, Germany, and elected member of the board of 5G-ACIA (5G Alliance for Connected Industry and Automation).

Clean radio spectrum is essential for the operation of radio services. During the panel “Keeping spectrum clean” a number of panelists raised concerns about the increasing noise due to more wireless devices using the spectrum and non-radio devices (such as computers and fixed line technologies) using ever higher frequencies. “The Amateur radio community struggles with an ever-growing level of electro-magnetic pollution that is crowding in across the radio spectrum from the lowest frequencies up into the VHF bands. In some frequency ranges, efficient and useful radio communication is becoming compromised,” insisted Barry Lewis, Microwave Manager at the International Amateur Radio Union (IARU), and continued, “Aftermarket regulation and slowly evolving standards are struggling to be effective in keeping the spectrum clean for all users.” Mitigating techniques and methods against the increasing background noise were also addressed during discussions, such as continuous radio monitoring.

Panelists agreed that progress has been made on more varied licensing and authorization regimes, with BNetzA in Germany having licensed the 3.7 – 3.8 GHz band, and Ofcom having identified that shared access to spectrum can help with market expansion, i.e. targeting areas that are not considered economic by mobile network operators.

Roland Götz, COO and board member of LS telcom AG, concluded: "This year again, we were able to attract renowned international speakers from a great variety of organizations to the Spectrum Summit. Around 200 delegates from impressive 34 nations across the globe were our guests at the LS telcom headquarters in Lichtenau. We are delighted that “Spectrum for Everyone & Everything” attracted so many international experts. The immense progress in the development and implementation of 5G is reflected in the keen interest in our Spectrum Summit. This also shows that the agenda as well as our products and services are exactly in line with the trend. It is amazing for us to see how this event has developed over the past 24 years to today's “must-attend event” in the spectrum management calendar.”

“What makes the Spectrum Summit so interesting and useful is that it brings together international stakeholders – regulators, manufacturers, academics, and users -- who share their expert points of view and experience with topics and issues from different angles. Delegates benefit from a diverse agenda providing unique theoretical and practical insights, facts, ongoing issues, and future directions in the industry,” confirms James Watson, Manager of Spectrum Business Analysis, ISED Canada and future Chairman of the USERgroup. He adds, “The event is always an excellent opportunity to network and share successes and challenges with colleagues and peers.”

The Spectrum Summit is followed by a workshop for German industries on local 5G licensing, the latest topic in Germany after the allocation of local 5G frequencies for industry by the German Federal Network Agency BNetzA. The Spectrum Summit and the post-conference workshops together with the two-day LS telcom USERgroup forum for LS telcom system and software users, make up a full week of events, which is organized by LS telcom. The Spectrum Summit is organized by LS telcom in conjunction with renowned spectrum policy publication PolicyTracker.

London, UK - Lichtenau / Baden, Germany, 18th June 2019 – LS telcom UK today announces that it conducted a study for the Commission for Communications Regulation (ComReg) in Ireland on network deployment and spectrum options for Terrestrial Broadband Public Protection and Disaster Relief (BB-PPDR). ComReg published the final report of the study today.

The research carried out by LS telcom was an input to ComReg’s proposed multi-band spectrum award consultation. The scope of the study was to determine how existing and proposed network deployment options i.e. using dedicated networks, commercial networks or a hybrid, and proposed spectrum options, could potentially impact the availability of future spectrum, particularly the 700 MHz duplex.
LS telcom performed analysis of the various network deployment and spectrum options, which included an extensive pan-European country feasibility analysis of the different technical alternatives to inform the findings.

The spectrum requirements calculation for BB-PPDR usage in Ireland found that 2 x 6 MHz is sufficient to meet all possible PPDR scenarios (in accordance with the LEWP-ETSI Matrix) and that there is no impact to ComReg to include the full 2 x 30 MHz in 700 MHz duplex in the multi-band award.

The final report published by ComReg feeds into ComReg’s public consultation for the multi-band spectrum award process which includes a section on BB-PPDR spectrum options to inform stakeholders of the outcome of LS telcom’s analysis.

Lichtenau/Baden, Germany, 31st January 2019 – LS telcom, an expert in spectrum management and 5G spectrum consulting, was welcomed as a new member by the 5G Alliance for Connected Industries and Automation (5G-ACIA) during the plenary meeting on 30th/31st January.

5G-ACIA is a new global initiative with the aim to optimize the applicability of 5G technology and 5G networks in the manufacturing and process industry by addressing, discussing and evaluating relevant technical, regulatory and business aspects.

Dr. Andreas Müller (Bosch), Chairman of the 5G-ACIA declares, “We are delighted to welcome LS telcom as a member of 5G-ACIA. LS telcom is a recognized expert with solid experience in the field of 5G, spectrum policy, technology and regulations. We are therefore already looking forward to numerous valuable contributions from LS telcom to the various ongoing activities of 5G-ACIA.”

LS telcom has already assisted the EU, the UK government, the transport industry and diverse industry associations with projects that focused on the technology evolution, impact on spectrum policy and co-existence studies as well as infrastructure requirements of 5G. LS telcom also provides training courses on 5G related matters and is a member of the University of Surrey’s 5G Innovation Centre (5GIC).

Dipl.-Ing. Roland Götz, COO and board member of LS telcom, said, ”We are looking forward to collaborating with the 5G-ACIA to contribute to the success of 5G in the industrial domain and to support the application of 5G for the different use cases and very diverse requirements of the industry.”

Bowie, Maryland, Lichtenau/Baden, Germany, 1st October 2018 – LS telcom Inc., a worldwide leader in spectrum management and monitoring solutions, today announced that it has delivered a comprehensive study of 5G spectrum compatibility to Intelsat and SES, leading providers of C-Band satellite services in the United States. The objective of this spectrum study was to analyze the characteristics and impact of signal interference as well as potential mitigation measures as a result of introducing 5G deployments in adjacent spectrum to existing C-Band satellite services.

As the FCC continues its comprehensive analysis of optimal spectrum for 5G, the use of a portion of 3.7GHz to 4.2GHz (commonly referred to as C-Band) has become a likely candidate. To better understand the potential impacts to existing C-Band satellite systems and users, the study analyzed the interaction between a hypothetical 5G network with the existing operational characteristics of the C-Band satellite in the 3.7GHz to 4.2GHz spectrum. The study provided by LS telcom covered multiple network components and a variety of operational scenarios to analyze and predict the potential impacts of 5G operations and the subsequent adjustments and mitigation techniques required for existing satellite and ground station equipment. 

“We are excited to be part of this dynamic time in spectrum management. As the push to 5G continues, the need to understand the impacts of adjacent systems and spectrum sharing are critical to the success of the next generation of wireless technology, as well as for the incumbent systems that are now being asked to share their spectrum resources,” stated Casey Joseph, Vice President at LS telcom, Inc.

“With our comprehensive solutions and global experience in spectrum management, LS telcom is uniquely positioned to help both new entrants as well as incumbent systems in this transition.”

The delivery included a report of findings based on several modeled locations as well as a software toolset enabling ongoing analysis of additional site locations and scenarios. The baseline of the solution leveraged LS telcom’s SpectrumMap, a visualization platform able to interpolate data from multiple sensor and source inputs to provide coverage predictions.

London, UK, Lichtenau/Baden, Germany, 6th August 2018 – LS telcom UK was commissioned by the UK Spectrum Policy Forum (SPF) to conduct a future looking study to examine the practicality, feasibility, and implications of defragmenting the UHF band 694 to 960 MHz.

SPF is the industry sounding board to Government and Ofcom on future spectrum management and regulatory policy with a view to maximizing the benefits of spectrum for the UK.

The study was initiated by the UK SPF in response to radical proposals to re-plan the 694 to 960 MHz band to remove the current fragmentation. The proposals claimed that such re-planning could potentially deliver considerable benefits such as increased capacity, future proofed spectrum and securing access for DTT services below 694 MHz. 

The LS telcom study found that the overall capacity benefits gained from the proposed defragmentation would be small compared to the gains promised by future technology developments such as 5G and the use of higher frequency bands. Further, LS telcom determined that the proposed defragmentation would impose a considerable cost burden on mobile network operators, who would need to upgrade every base station in their network, for a fractional increase in capacity.

Project manager, Saul Friedner, Associate Director of Spectrum Services at LS telcom said, "This was a challenging project due to the future looking nature and the requirement to determine what a mobile network might look like in 2030. Whichever way we looked at the problem we could see no significant justification to undertake such a defragmentation exercise.”

Lichtenau / Baden, Germany, 5th July 2018 – “Future of Broadband – Beyond Consumer Broadband” was the theme of the 23rd Annual Spectrum Summit concluding yesterday at LS telcom’s headquarters in Lichtenau/Baden Württemberg, Germany. The conference featured presentations and panel discussions on 5G services, new use cases and spectrum requirements for vertical markets, as well as the future of radio broadcasting in the light of 5G. The event attracted representatives and thought leaders from regulatory authorities, mobile and broadcast operators, spectrum consultants, research institutes, industries and industry associations. Presenters and participants of the different panels set out their vision on 5G. It became clear from the day’s presentations and subsequent discussions that 5G has the potential to go far beyond serving consumer broadband. New market opportunities and completely new business models are being driven by 5G, in particular for industry verticals, such as manufacturing industries, healthcare and transport. “Ultra reliability, low latency and massive connectivity together with other technology developments will enable solutions for individual use cases. The question is to what extent operators are willing to slice up their capacity to deliver these services and whether individual users have to provide and operate their own 5G networks,” said Martin Sims, Managing Director, PolicyTracker. Panelists agreed that new approaches are necessary and that existing business models have to be completely rethought. Saul Friedner, Associate Director, Spectrum Services at LS telcom, summarized, ”While new and more varied licensing and authorization regimes have to be introduced to allow industry verticals access to spectrum, industry will at the same time have to manage the spectrum much more efficiently, as usage is becoming increasingly complex.” Radio broadcasting is facing turbulent times as broadcasters struggle to develop viable business plans in an increasingly digital and streaming led world. Richard Womersley, Director of Spectrum Services for LS telcom opines, “With streaming services such as Spotify and increasingly available mobile broadband capabilities, the way in which people consume music is changing. FM broadcasting continues to lead digital platforms, including DAB, but this will change and radio broadcasters will need to innovate and adapt to maintain their relevance.” Mark Rider, Business Solutions Architect at Ofcom UK, commented, “This is my 12th time attending the annual Spectrum Summit. The Summit has an excellent line-up of speakers and experts from around the world. The diverse agenda provides great theoretical and practical insight of current developments within the sector. The Spectrum Summit is a must-attend event for anyone who wants to stay informed about latest trends in the industry.” Roland Götz, board member of LS telcom AG, concluded, “We were able yet again this year to attract a wide range of expert speakers to the 23rd Spectrum Summit. In addition to regulatory and media authorities, telecom institutions and operators, we had experts from an even wider range of industrial companies; such as AirFrance, Bosch and the SNCF Group, as well as AGURRE, the association representing industrial radio users. This demonstrates that the Spectrum Summit is well-known and well-respected, but also that 5G is a top priority on the agenda of industry verticals that are ready to take things forward.”

Lichtenau / Baden, Germany, 5th March 2018 – Following a joint-development effort with FCS Flight Calibration Services GmbH, LS telcom’s Colibrex announces the launch of NavAidDrone, a drone-based system for navigational aid (NAVAID) inspections.
The NavAidDrone is used for field measurements required for commissioning and regular maintenance of Instrument Landing Systems (ILS). It will support Air Navigation Service Providers, NAVAID system manufacturers, and CNS (communication, navigation, surveillance) installation and maintenance service engineers. The system can also perform VOR and GBAS measurements with additional software included.
Measurement data, processed by the NavAidDrone, will now be available for areas that cannot be accessed by vehicles or conventional telescopic masts and for which measurement was therefore previously not possible. For instance, the NavAidDrone measures localizer coverage with ease in a sector of ± 35° towards the antenna as it can be fully programmed to fly orbit paths. The airborne measurement system can also detect high frequency oscillations of ILS signals caused by buildings, cranes or other construction work obstacles.
Luc Haeberlé, Managing Director of Colibrex explains, “The integrated high-performing FCS receiver guarantees extremely accurate measurement results. At the same time, the flexible airborne platform delivers a much higher volume of measurement points and results, compared to ground measurements. Altogether, the measurement results obtained with the NavAidDrone are much more comprehensive and precise and improve ILS periodical measurements, adjustment and maintenance work substantially. At the same time, the use of NavAidDrone is more cost-effective and will also potentially reduce flight inspection hours.”
Rüdiger Schmidt, Managing Director of FCS, adds, “Drone-based ILS measurement opens the way to a new era in NAVAIDS inspection and FCS together with Colibrex are at the forefront of this exciting and complementary approach to flight inspection. Flight inspection and ground measurements should go hand in hand to ensure the best performance of our client's NavAids. Our exciting new technology very effectively bridges the gap between the two worlds.”
The NavAidDrone unites the flight inspection and receiving and processing expertise of FCS Flight Calibration Services GmbH and Colibrex’s expertise in the design and international commercial operation of unmanned aircraft systems for radio frequency measurements.
Colibrex and FCS are planning a follow-up development and launch of the “RadarDrone” to perform field measurements for commissioning, trouble-shooting and regular maintenance of military and civil radar and surveillance systems, including primary (PR) and secondary (SSR/MSSR) radar installations. The Air Navigation Service Providers and CNS maintenance staff, radar system manufacturers and radar service organisations will benefit from this new drone-based measurement technology.

London, UK, Lichtenau / Baden, Germany, 9th January 2018 – LS telcom UK has produced a report for Britain’s railway to support improved digital connectivity for customers. The research project was commissioned by the Rail Safety and Standards Board on behalf of the Future Communications and Positioning Systems Advisory Group.

The research report proposes a 3 to 5-year technology roadmap, and identifies commercial deployment models for improving high-speed mobile internet connectivity for passengers, as well as passenger and freight train operations. According to the study, wireless technology solutions including a mobile variant of Wi-Fi, 4G, and potentially 5G, are available within the suggested timeframe. Successful deployment of internet connectivity depends on which business model is adopted to ensure that train operating companies can meet the Department for Transport’s connectivity requirements.

The Future Connected Rail Stakeholder Forum (FCRSF) and the Future Connected Train and Customer Communications Steering Group (FCTCCSG) asked for the study to improve cross-industry involvement on the implementation of digital connectivity across the entire rail network.  FCRSF and FCTCCSG are collaborations between the Rail Delivery Group, which brings together train companies and Network Rail to improve the railway; techUK, on behalf of the digital industries; and Network Rail, the company managing Britain’s rail infrastructure. RSSB is also a member of FCTCCSG.

Nick Wilson, Rail Delivery Group, on behalf of the Future Connected Train and Customer Communications Steering Group, said that “This work has helped us to identify the range of technical and commercial options available.  It will inform the rail and digital industries on improving digital connectivity (mobile and broadband) across all of Britain’s rail network for the benefit of rail customers and the train operating companies, freight operating companies and rolling stock companies. In addition, the study will inform government of associated investment opportunities and the shaping of policies to maximize them. The study should generate the further essential collaboration between all relevant stakeholders, to enable the connectivity that Britain needs in the years to come.”

The publication of the report coincides with the Department for Digital, Culture, Media & Sport, and the Department for Transport’s launch of a call for evidence on ‘Commercial options for delivering mobile connectivity on trains’. The findings from the report could help to provide some information to this call for evidence.

An event will be organized on 6th of February at techUK that brings the rail sector, digital industries and government together to discuss the report in the context of the UK’s ambition on rail connectivity.

London, UK, Lichtenau/Baden, Germany, 18th December 2017 – LS telcom today announces the publication of a report produced for Ofcom to better understand the impact of mobile signal attenuation inside vehicles. Together with Siroda, a specialist in RF signal measurements, LS telcom conducted a study, which included a unique in-car mobile signal measurement campaign. The report “In-car Mobile Signal Attenuation Measurements” presents a comprehensive set of in-car mobile signal attenuation results as well as statistical analysis of the measurement data.
The unique aspect of the study required careful consideration of undertaking mobile signal attenuation inside vehicles, which covered all of the mobile frequencies in use by the mobile network operators including 800 MHz, 900 MHz, 1800 MHz, 2100 MHz and 2600 MHz. The drive test was repeated for a range of popular vehicle types found in the UK and measured the mobile signals in urban, suburban, and rural areas along a 100 km route.
The empirical data will be used by Ofcom to help conduct mobile signal coverage predictions for UK’s roads and also better understand the signal quality that can be received by consumers inside vehicles.

The complete report

Lichtenau / Baden, Germany, 22nd November 2017 – The European Telecommunications Standards Institute (ETSI) has officially adopted results from LS telcom’s study “Coexistence of GSM-R with other Communication Systems” commissioned by the European Union Agency for Railways. The LS telcom report examined the possibility of using the ER/R-GSM spectrum by other radio communication systems for railways in coexistence with the existing GSM-R system operated in that frequency band. The objective of the study was to find out whether new spectrum is required for a successor system or whether band sharing during migration from GSM-R to its successor would be feasible.

The results of this study are integrated in the ETSI System Reference document (SRDoc) TR 103 333 about GSM-R networks evolution. This document intends “to describe the spectrum requirements for a European system for operational railway communications between a terrestrial ground network and a train, based on 4G/5G technology, and operating in the band 873 - 880 MHz paired with 918 - 925 MHz, in coexistence with the already deployed GSM-R technology.”

Both, LS telcom’s study and ETSI’s System Reference document are part of a joint effort by the Union Internationale des Chemins de Fer (UIC), the European Union Agency for Railways, the GSM-R industry and other railway stakeholders across Europe in close cooperation with ETSI to define and specify the next generation solution “Future Railway Mobile Communications System” (FRMCS), including future spectrum requirements.

A key challenge is that spectrum is needed for both the FRMCS and GSM-R during the migration phase. An update of the EU legal framework is necessary to make available additional harmonized spectrum in order to guarantee European railway interoperability.

London, UK, Lichtenau/Baden, Germany, 23rd October 2017 – LS telcom today announces the publication by the European Commission of the “Study on Spectrum Assignment in the European Union”. The report, written by LS telcom together with PolicyTracker and VVA, examines the approaches used by EU Member States for authorizing and assigning spectrum with a view to determining which methods might be most appropriate in the context of future 5G services and the development of industrial sectors, so called vertical markets, in the European Union.
“This study will inform regulators, operators and service providers of electronic communications of the benefits from adopting alternative approaches to spectrum authorisation and assignment. These approaches could unlock access to different services using 5G technologies that may otherwise have been delayed. More flexible use of these approaches improves spectrum efficiency and ultimately improves access to connectivity for enterprises and consumers,” reports Saul Friedner, Associate Director, Spectrum Services at LS telcom.
According to the study, the spectrum access requirements of the ‘vertical’ services, which have specific technical and performance characteristics, differ widely from the requirements of mobile services, and are driving the way in which spectrum will be used, and the associated regime under which it should be authorized and assigned. The study found that assignment approaches should be harmonized across Member States, especially for higher frequency bands (e.g. 26 GHz), and appropriately sized blocks considered, when authorizing spectrum for different services.
“The findings of the study will provide additional elements in the context of the ongoing negotiations with the European Parliament and the Council on the Commission Proposal for a ‘European Electronic Communications Code’ (EECC). The study will be further exploited in the context of the implementation of the Commission 5G Action Plan,” as indicated in the EU press release.

When will exponential mobile growth stop?

London, UK, Lichtenau/Baden, Germany – LS telcom today announces the publication of a report entitled “When will exponential mobile growth stop?”

Richard Womersley, Director Spectrum Consulting of LS telcom, explained the rationale for the study, “Exponential growth cannot continue indefinitely as the result would be that whatever is growing will eventually reach an infinite size. We wanted to examine more closely how future mobile data traffic will really evolve and whether current estimates of continuing exponential growth until at least 2030 are valid, in order to inform ongoing activities to identify new spectrum bands for 5G.”

LS telcom experts first calculated how much data an individual may be able to consume to determine what a finite limit to mobile data usage might be. This resulted in the surprising conclusion that even using extreme values for potential personal data use (such as every person on the planet streaming Ultra-High Definition 4K video for 16 hours per day), the majority of growth in mobile data traffic would still be complete by the late 2020s.

Secondly, the study examined the growth in mobile data usage in a number of advanced countries where users are already ‘ahead of the curve’ with respect to their usage of mobile data. Three countries were identified where mobile data growth is already showing signs of slowing down and in each case, it is clear that the reason for this slow down is not related to spectrum availability. In these countries, there may only be a factor of three to four times mobile data traffic growth remaining, according to the report. This appears to be a trend. The study also surmises that data growth only continues to show exponential characteristics in those countries where digital divides remain or where connectivity is still being rolled out.

Systems delivered as part of USAID technology package for the Liberian Telecommunications Authority (LTA) 

Bowie, Maryland / USA, Lichtenau/Baden, Germany, 26th September 2017– LS telcom, Inc., a worldwide leader in Spectrum Management and Spectrum Monitoring solutions, today announced the installation of  multiple LS OBSERVER sensor-based monitoring stations for the Liberian Telecommunications Authority (LTA).  The purchase of the systems was facilitated through the non-governmental organization (NGO) NetHope as part of a USAID technology package for the country. Following the Ebola crisis in 2014-2015, improvement in communications was identified as a top priority for the country.  Working together with USAID, NetHope selected LS telcom as the superior technology solution for LTA’s requirements.  The acquisition of the LS OBSERVER technology provides LTA with the foundation of spectrum monitoring capability including identification of spectrum conflicts, identification of free spectrum, isolation of dead zones in coverage, and locating rogue networks. 

“We are very pleased to have this new capability.  As I consider radiofrequency a scarce resource for Liberia, the LS OBSERVER monitoring stations will allow our team to fully optimize spectrum policy and increase the enforcement capability at LTA,” said Henry W. Benson, Commissioner for Engineering & Technology at the LTA, “This technology is a key part of our mission to improve communications for our country.”

“LS telcom is excited to be part of the USAID technology deployment in the African region.  As the pace of spectrum management accelerates, regulators need to be equipped with the proper tools and capabilities to stay ahead,” said Casey Joseph, Vice President of Sales and Business Development, “With the LS OBSERVER stations in place, LTA is positioned to modernize their spectrum management capability throughout the country.” 

As the African continent deploys next generation wireless networks, regulators must maintain pace with the requisite capabilities to monitor and regulate activity.   The LS OBSERVER monitoring system delivers state of the art sensor-based monitoring capabilities across the commercial spectrum.  Available in fixed and portable versions, the LS OBSERVER is ideal for regulators to monitor, establish and maintain a spectrum inventory or support spectrum inventory activities, and enforce spectrum usage policies and procedures.  As the value of spectrum continues to increase, LS OBSERVER can also be used to identify areas of unused spectrum that can be reallocated and licensed for future use.  The technology package is being delivered to Liberia through NetHope, the leading technology NGO in the region.  The monitoring systems are part of a larger USAID recovery package for the country. 

Lichtenau/Baden, Germany – LS telcom announced that organizations now have the possibility to validate real world radio coverage for an area of interest with their new solution SpectrumMap. As a cloud based big data system SpectrumMap gathers real spectrum usage data from a monitoring network and presents the data on a map in a fast, user-friendly way. The system collects and stores spectrum data from many monitoring sources, such as fixed sites, temporary sites, mobile, handheld and portable devices. The equipment can be from different providers and manufacturers. The easy to use interface allows even staff, not qualified as engineers such as policy makers, band planners, licensing teams, as well as skilled engineering teams, and enforcement to use a range of analytical tools via web apps. Measured and calculated spectrum coverage data can be visualized in many ways such as by band, channel or service type. Key applications, which are available as web apps, include:

·        Field strength of single frequencies to bands, all user selectable

·        Coverage analysis of user selectable bands

·        Band occupancy

·        Spectrum use

·        Electromagnetic radiation hazard analysis

·        Dynamic band analysis where the display steps through user selectable frequency steps

In contrast to conventional control units of monitoring systems, SpectrumMap focuses on presenting the data in a geographical area rather than needing to identify monitoring sites and individually calculate coverage of each site.

Manfred Lebherz, CEO of LS telcom explained, “With SpectrumMap regulators can now for the first time base their licensing scheme on real world measured spectrum usage not just prediction. This is especially useful in urban areas, where spectrum is very densely used. We are sure that SpectrumMap will be indispensable for regulators with the introduction of 5G services, the Internet of Things (IoT) applications and connected objects.”

200 delegates from 33 countries worldwide attended Europe’s largest Annual Spectrum Summit, hosted by LS telcom in Lichtenau / Baden

Spectrum Summit 2018 on 4th July 2018

Lichtenau / Baden, Germany – “Driving wireless innovation” was the theme of the 22nd Annual Spectrum Summit concluding yesterday at LS telcom’s headquarters in Lichtenau / Baden Württemberg, Germany. 

The conference featured presentations and panel discussions on spectrum policy, 5G, the Internet of Things (IoT), and Digital Terrestrial Television (DTT), and attracted representatives and thought leaders from regulatory authorities, mobile and broadcast operators, spectrum consultancies, research institutes, and industry associations. 

Rupert Pearce, Chairman of ESOA, the Association of satellite operators in Europe, the Middle East and Africa, and CEO of Inmarsat, opened the event with his keynote - a thoughtful consideration of the role of spectrum as infrastructure: “In the emerging global digital society, connectivity is a mission-critical enabler as important to the planet as clean water. Spectrum is infrastructure – not merely ‘fuel’ for broadcast and broadband networks, but instead the catalyst for pervasive, interoperable, heterogeneous, ultra-reliable next generation networks which will break down the digital divide and support a more productive, innovative, healthy, safe and fair world.” 

Representatives from industry, government and international regulatory bodies presented and discussed the challenges of network deployment and future spectrum access for 5G. “The challenge of 5G lies in ensuring that the right spectrum is available to operators and service providers who will make the most valuable and efficient use of it. A diverse mix of vendors, operators, verticals, regulators and infrastructure owners will need to work together to truly make the benefits of 5G a reality within the next five years,“ concluded Saul Friedner, Associate Director Spectrum Services, LS telcom. 

The Internet of Things (IoT) took centre stage in the panel discussion moderated by Martin Sims, Managing Director, PolicyTracker (co-organizers of the event). Together, he and his panelists tried to tease out the likely development of IoT and examined whether the existing approach to spectrum, regulation and technology policy can ensure its future success.

The session “Digital Terrestrial Television of the future – more or less”, moderated by Richard Womersley, Director of Spectrum Services at LS telcom, explored the continuing role of DTT as part of the changing television landscape and examined whether and how DTT will need to adapt to face the challenges of the future.

It became clear from the day’s presentations and subsequent discussions that many challenges and difficult decisions are still to be made by operators and regulators and that certainty of the spectrum regulation is paramount to the future success of wireless industries, and to satisfy growing demand for widespread connectivity. 

James Watson, Manager, Business Analysis, Business Intelligence and Transformation at Innovation, Science and Economic Development Canada (ISED), commented: “This was my sixth time attending the annual Spectrum Summit. Every year, very well informed speakers give excellent insights into the latest technological and policy developments from many perspectives. This really is a ‘must attend’ event, if you want to be ahead of trends in spectrum management and the wireless industry, and to network and share experiences with industry colleagues from around the world.” 

Roland Götz, COO and board member of LS telcom AG, said: “With a wide range of expert speakers presenting various aspects and different points of view on spectrum regulations and technological innovation, combined with profound discussions among international experts, the Spectrum Summit was once again a great opportunity to get first-hand information on the latest radio regulation and technology trends.

Rheinmuenster, GermanyColibrex, the pioneer and worldwide market leader in drone based radio frequency measurements, today announced that it has recently completed countrywide antenna measurements for the Malaysian DVB-T2 broadcast operator MYTV Broadcasting Sdn Bhd. It is the first time that these drone measurements are performed in Asia.

The new Malaysian DVB-T2 broadcast operator MYTV is in the midst of implementing and rolling out their nationwide Digital TV network. As part of the network deployment, MYTV has to install new DVB-T2 transmitter systems all over the country. As most of the new antennas have to be mounted on existing towers, it is even more crucial to verify the transmission characteristics of these new installations.  

Colibrex and its long-standing Malaysian partner Wamata Solutions Sdn Bhd started work several months ahead of the actual measurements to obtain the necessary flight approvals and to schedule the flights. The work included organizing the logistics, coordinating the measurement flights with various authorities and obtaining appropriate approvals, e.g. from the Malaysian Department of Civil Aviation (DCA). 

The drone measurements enabled MYTV to detect installation errors, incorrect antenna configurations and factory faults on the newly installed antennas. MYTV was able to take immediate corrective measures together with the system supplier. 

“We are excited to be the first broadcaster in Asia to use Colibrex´s drone based measurement, and the results have been encouraging. Knowing how the antennas perform in their real environment and having the opportunity to immediately engage corrective measures with the system supplier or with the owner of the masts are of great benefit to MYTV. The Colibrex solution led to savings in both costs and time. We are already preparing the measurement of additional sites as we believe we will realize the same positive impact on our budget and time schedules as with the preceding measurements,” said Michael Chan, CEO of MYTV. 

Colibrex has already realized over eight hundred successful measurements in similar projects across Europe, Africa, North and South America.

Measurement confirms broadband antenna pattern for soon to be repacked station

Bowie, Maryland - Lichtenau / Baden, Germany – LS telcom, a worldwide leader in Spectrum Management and Spectrum Monitoring solutions, today announced that it has recently completed broadcast measurements in Cedar Hill, Texas, USA, via unmanned aircraft system (UAS). The measurement validated both the horizontal and vertical transmission patterns of a newly installed broadband antenna for a local Dallas television station. Leveraging the precision flight of the UAS combined with a specialized measurement payload, the key data was captured over a two-day period at the Cedar Hill facility this month, as part of the local network’s preparation for the upcoming repack.

With the recent completion of the FCC Broadcast Incentive Auction, over nine hundred television stations across the United States are being repacked to new channel assignments. In a compressed timeframe of just thirty-nine months to complete the nationwide process, broadcasters are searching for capabilities and technologies that increase the efficiency of the equipment installation process. LS telcom’s UAS Broadcast Measurement allows broadcasters to capture equipment performance at its source and avoid the lengthy process of drive testing hundreds of square miles to validate basic operation. The measurement data captured can be input into network planning tools for additional analysis, allowing broadcasters to compare the actual transmission patterns of the network with the theoretical projections. UAS Broadcast Measurements represent a huge savings in time, manpower, and testing effort for broadcasters, network installers, and equipment vendors.

“We are pleased to be able to bring this innovative technology to US broadcasters. As the industry faces the compressed time frame of the repack, LS telcom’s UAS Broadcast Measurement can optimize installations and rapidly provide broadcasters with the key baseline measurement of their network’s performance,” said Casey Joseph, Vice President of LS telcom Inc. Broadcasters preparing for network equipment upgrades can include UAS Broadcast Measurement as a service in their network repack plans being filed with the FCC.

With over eight hundred successful measurements to its credit, LS telcom (through its subsidiary Colibrex) is the global leader in UAS Broadcast Measurement. The processes and procedures for these measurements have been approved for operations in over fifteen different countries around the world. For the Cedar Hill measurement, LS telcom operated under an FAA approved Part 107 waiver giving access to the necessary airspace for the mission. LS telcom is currently scheduling the UAS Broadcast Measurement service throughout the USA for validation of current broadcast network operations, as well as new equipment installations.

London, UK – LS telcom UK Ltd with its partners WHP Telecoms Ltd and InterDigital Europe Ltd have written a report on behalf of the National Infrastructure Commission, which examined the potential to enable existing telecommunications infrastructure for future networks. The report was published yesterday, 14th December 2016, alongside the NIC’s own report on 5G infrastructure, which has made some key recommendations to Government on investment in telecommunications infrastructure.

The report assessed both the fixed and mobile telecommunications infrastructure deployed in the UK today with a view to enable future high-speed connectivity nationwide.

The study focused, in particular, on the nationwide road and rail telecoms infrastructure to determine whether the available fixed fibre capacity could potentially be used for providing high-speed wireless connectivity to road users and rail passengers. The study determined the gaps in the required number of sites needed to fulfill the network performance targets and estimated the capital cost of the equipment deployments. 

The study also considered the impact on network densification in urban areas, which would be needed for the future enhanced mobile broadband services of 5G. It further mentioned the need to fix the coverage gaps in rural areas in order to meet the overall 5G Vision.
Some of the major challenges in deploying higher capable infrastructure were identified in the report including how access to fixed non-telecoms infrastructure and more fibre at these locations would be needed.

A spokesperson from the NIC said, “We chose LS telcom for their extensive experience and expertise in assessing telecommunications infrastructure and spectrum demand. Their study made a significant contribution to the evidence base underpinning our report, which provides advice to the government on 5G infrastructure challenges. LS telcom’s work provides important input to informed decision-making on 5G infrastructure in the UK. “

Lichtenau, Baden / Germany – LS telcom’s spectrum management and licensing system, SPECTRA Enterprise, is now fully operational at the Australian Communications and Media Authority (ACMA) after a multi-year implementation project. The ACMA chose a SPECTRA Enterprise system from LS telcom to support, enable and enhance the ACMA’s spectrum management capabilities. The system includes software for spectrum licensing, broadcast license area planning and allocation, technical frequency assignment, device registration, spectrum auction planning, and apparatus licence management.

SPECTRA Enterprise fully interfaces with the ACMA’s third-party auction, CRM and financial management systems, as well as the ACMA’s B2G (business to government) portal ALF-E. Over twenty-five radio communication services, divided into more than one hundred sub-services, are handled by the system. Thirty workflows support the automation of sophisticated licensing, business and technical analysis processes passing through the different systems and departments.

Rohde & Schwarz, prime contractor and LS telcom’s partner for Australia for nearly twenty years, supported the ACMA team and LS telcom in the realisation of the project with a significant contribution to project implementation and customer relationship management.

Mark Loney, Executive Manager of the ACMA’s Operations, Services & Technology Branch, confirmed, “The SPECTRA Enterprise system from LS telcom has increased the productivity of ACMA staff and provided Accredited Persons with the ability to lodge complete licence applications on behalf of their clients. The integrity of licence data has improved with the introduction of SPECTRA and the use of licensing workflows to process electronically lodged applications has improved processing turnaround times. With the SPECTRA Enterprise system we now have the infrastructure in place and are well-positioned to implement the government’s spectrum reform agenda.”

The Australian spectrum reform agenda provides increasing opportunities for market-based arrangements, including spectrum sharing and trading, as well as secondary markets, which the software system will support. SPECTRA Enterprise also produces the data published in the Register of Radio Communications Licences, which the ACMA makes freely available from its website through downloads and APIs (application programming interface).

The implementation project finished with the final acceptance in May 2016. It was split into several phases. LS telcom experts brought in their broad expertise in data management and analysis, data cleansing and re-structuring. They migrated all the ACMA spectrum data from several legacy systems into SPECTRA, which provides the ACMA today with one centralized master database and a single view of the national spectrum.

Dr. Georg Schöne, CTO and Board Member of LS telcom, emphasizes, “Completing this project for the ACMA, which included a mix of SPECTRA commercial-off-the-shelf modules and very specific customization to meet challenging Australian spectrum management requirements, adds to our long record of success, and that even with the geographical distance and time zone differences to the ACMA. Once again, we have demonstrated our capabilities in managing and realizing multi-phase, multi-dimensional projects as we have already proven before, i.e. at ISED Canada, Ofcom UK, BNetzA Germany, and several world-class regulators in the Middle East. As for all projects of this size, LS telcom has established a permanent local first-class support which is realized in a joint effort by our reliable local partner Rohde & Schwarz and us.”

London, United Kingdom – LS telcom, the leading worldwide provider of spectrum management systems, today announces that the UK Ministry of Defence (MOD) will be using its SPECTRA spectrum management system as part of the MOD’s contract with CGI. The commercial off the shelf SPECTRA system will build upon the Ministry’s existing Spectrum Portal to extend and improve the MOD’s spectrum planning, engineering and enforcement capabilities.

The extended, entirely integrated, and inter-operable spectrum management system enables spectrum managers to allocate and assign the electromagnetic spectrum more effectively. The process automation of the system secures and accelerates processes to improve decision-making, and is another contributor to more efficient spectrum use. This is essential with military spectrum becoming increasingly congested and contested.

The SPECTRA spectrum management system is in use at the UK Spectrum Regulator Ofcom, and in over 100 countries around the world.

The contract held with CGI will provide integration and support services for the MOD’s Spectrum management capability. CGI has worked with the MOD for 40 years and has built a reputation for delivering secure end to end information solutions.

MOD’s Tessa Mulhall, Head of Spectrum, said: “The award of this spectrum management contract extends our close working relationship with CGI. This will expand our vital service which provides Defence with greater understanding of our spectrum usage, allowing us to better support the UK Government’s Spectrum Strategy and Defence operational capability.”

Georg Schöne, Chief Technical Officer of the LS telcom Group, commented: “We are glad that the UK MOD and CGI selected our spectrum management system SPECTRA for this important project. This proves yet again our credibility to provide large integrated, automated and inter-operable systems for highly efficient civil and military spectrum management.”

Lichtenau, Baden / Germany – The European Union Agency for Railways has recently published a report by LS telcom on the possibility of using the ER/R-GSM spectrum by other radio communication systems for railways in coexistence with the existing GSM-R system operated in that frequency band. The objective of the study was to find out whether new spectrum is required for a successor system or whether band sharing during migration from GSM-R to its successor would be feasible.

Thomas Chatelet, ERTMS Project Officer at the European Union Agency for Railways, said, “Their study will contribute to informed decision-making for the railway industry’s future spectrum requirements. We were very satisfied with the work carried out by LS telcom and we look forward to working with them again.”

LS telcom reviewed several technologies, which met the rail industry’s needs, and identified LTE / LTE Advanced as the only feasible technology currently available. The study further showed that the implementation of an LTE system within the R-GSM band in co-existence with the current radio system is unlikely to be feasible unless a number of mitigating measures are taken.

LS telcom carried out feasibility and compatibility analysis, which were complemented by capacity and coverage simulations and by laboratory measurements made by the Dresden University of Technology.

The study concluded that the extent and necessity of the mitigation methods should be tested through field trials. Furthermore, an evaluation of the potential degradation of the quality and capacity of the existing GSM-R system should be conducted to identify whether the potential degradations caused by the implementation of an LTE carrier are acceptable. Future demand for data for rail services should also be examined to determine whether the resulting capacity is sufficient.

Global Leader on Spectrum Management Enhances CHIRplus_BC with support for the ATSC 3.0 Standard

Bowie, Maryland - LS telcom, Inc., a worldwide leader in Spectrum Management and Spectrum Monitoring solutions, today announced that it has integrated support for the recently approved Advanced Television Systems Committee (ATSC) 3.0 standard into its CHIRplus_BC Broadcast Planning Tool. The integrated solution provides comprehensive capabilities for planning OFDM based broadcast networks including coverage propagation analysis, interference mitigation, best server determination, and Single Frequency Network (SFN) planning. A critical step in the evolution to the Next Generation TV digital broadcast technology, the deployment of ATSC 3.0 delivers broadband throughput enabling the delivery of custom content, improved streaming capabilities and support for a wide array of on demand options.

As the Over-the-Air (OTA) broadcast industry faces the reality of a post-Incentive Auction repack into a compressed allocation of spectrum, as well as increasing competition from Over-the-Top (OTT) streaming applications, the spectral efficiency and broadband throughput provided by the ATSC 3.0 standard is necessary for network viability. "OTA Broadcasters are facing increasing competition in the next two to five years. Their deployment of ATCS 3.0 is critical to maintain the throughput required to offer a competitive service," said Casey Joseph, Vice President of Sales and Business Development. "These broadcasters represent a vital component of the communications fabric in the United States. With LS telcom's CHIRplus_BC support of ATSC 3.0, broadcasters can be assured that they are maximizing the network throughput while maintaining a consistent footprint as they move through the transition to the next generation of technology."

The CHIRplus_BC planning tool is currently used by OTA broadcasters and spectrum regulators around the world for accurately planning their broadcast network capabilities. Already supporting a global footprint of users for DVB-T2, the addition of the ATSC 3.0 support expands the reach of CHIRplus_BC to the Next Generation TV market in the United States as OTA broadcasters evolve to the next generation of digital broadcast capabilities. With integrated support for the requisite FCC database information, integrated maps, population coverage, and a comprehensive list of supported propagation algorithms including OET-69 Longley-Rice, CHIRplus_BC delivers a compliant planning capability with comprehensive configuration options that allow network engineers to maximize the operation of the ATSC 3.0 standard to deliver the highest throughput possible. Additionally, to further improve the accuracy of the projected coverage mapping, the CHIRplus_BC toolset supports the incorporation of custom antenna broadcast patterns captured by Colibrex ( UAS (Unmanned Aircraft System) based measurements. This custom input collected from the installed antenna array delivers the most accurate antenna input for the broadcast propagation analysis. To best serve the range of broadcaster needs, LS telcom is offering CHIRplus_BC for purchase as well as a cloud based service. 

Lichtenau, Baden / GermanyLS telcom, together with its local partner and prime contractor PT Berca Hardayaperkasa, will implement its sensor-based radio monitoring system LS OBSERVER for the Ministry of Communication and Information Technology, Directorate General of Resources and Equipment of Posts, Telecommunications and Information Technology (SDPPI), Indonesia. SDPPI will use the system for nationwide radio monitoring and automatic violation detection. The new system will enable SDPPI to continuously monitor the complete spectrum and to detect illegal and unwanted radio frequency emissions immediately. The project with a total volume of about 6.3 million Euro, of which a main share is dedicated to LS telcom’s products and services, consists of more than sixty fixed remote monitoring units, which will be distributed all over Indonesia, and a large number of central control units, located in SDPPI’s regional offices and their headquarters.

Dr. Manfred Lebherz, CEO and board member of LS telcom, explained, “Automatic violation detection necessitates true integration of spectrum moni­toring systems with the spectrum management licen­sing database, as well as sophisticated data analysis soft­ware. We will provide this together with unique storage, mining, and post-processing capabilities for Big Data in our LS OBSERVER system. It is the first time ever that a system of this kind and complexity is installed at a national level.”

SDPPI operators will be able to detect unlicensed transmitters and identi­fy transmitters, which are not ope­rating within their licensed parameters. Based on the licensed transmitters’ parameters in the licensing database, the integrated software calculates which signal strength should be received by a given monitoring sta­tion at its location. If the measured signal strength does not correspond to the calculated “should-be” signal strength, the operator receives an automatic alert and can take action immediately.

Duta Subagio Sarosa, Director of PT Berca Hardayaperkasa, said “Following the implementation of LS telcom’s fully automated and integrated radio monitoring system LS OBSERVER, SDPPI will be able to react much faster to illegal frequency use and ultimately increase efficiency in spectrum control and management. The system to be built will be a first step in gradually and automatically building a massive but flexible spectrum inventory for future use.”

Lichtenau, Baden / Germany – LS telcom together with its partner VVA has completed a study on future spectrum needs for wireless services in Denmark for the Danish Energy Agency (DEA). In preparation of the WRC 2019, the DEA wanted to get an independent view on the demand for radio spectrum in order to help shape Danish and European spectrum policy. The study considers several spectrum-using markets, such as mobile broadband, backhaul, short-range devices, and the transport market. The growth of the markets themselves was examined as well as the impact of changes in technology on spectrum demand over the next 5 and the next 10 years.

The study found that the amount of spectrum needed for mobile data services will increase by a factor of between 3 and 8 times by 2021 and by a factor of between 9 and 14 times by 2026 respectively. Although the bands already identified for IMT will increase the amount of spectrum available for mobile services in Denmark by a factor of two, there will be a shortfall of 500 MHz of spectrum in urban areas by 2021 and a total of over 4000 MHz by 2026 if there are no further spectrum efficiency gains. The study also provides recommendations and suggestions of spectrum bands and technologies to overcome these shortages.

Concerning backbone spectrum needs, it all depends on the extent to which fiber will displace the need for microwave links. The analysis forecasts that the number of wireless links will not rise, but the capacity required of each link will. Therefore, no further spectrum will be needed within the next five years. However, a need to overlay higher capacity links in the bands between 60 and 90 GHz in a timescale of 5 to 10 years will require the DEA to prepare for licensing of these bands.

The report further forecasts that no additional spectrum is required for Wi-Fi, smart meters and PMSE, apart from for major events, when there may occur problems sharing the existing channels. According to the report, there is also no need for additional spectrum for aeronautical, maritime, road and rail transport over and above that already identified. For PMR, however, the report foresees a possible reduction in the demand for spectrum.

LS telcom continues to support ISED by providing maintenance services for the SPECTRA Enterprise system.

Lichtenau, Baden / Germany - LS telcom together with its partner VVA has completed a study for the European Commission (EC) on repurposing the 700 MHz spectrum. The report of the study, 'Economic and Social Impact of Repurposing the 700 MHz band for Wireless Broadband Services in the European Union', was published by the European Commission on 23 February 2016. The analysis provided in the study is informing work by the EC on developing a proposal for a Decision of the European Parliament and of the Council on the use of the 470-790 MHz frequency band across the European Union.

The study examined various policy options for the future use of the UHF television band including the so-called 700 MHz band (694 - 790 MHz) which was identified for IMT usage at the recent ITU World Radiocommunication Conference. It followed a report in Europe authored by Pascal Lamy, who had proposed a number of options for the band with varying degrees of flexibility in the use of the spectrum below the 700 MHz band, ranging from retaining its use for digital television, to converting the whole band for mobile broadband use.

Andreas Geiss, head of the Commission's spectrum policy unit said, "We chose the LS telcom and VVA consulting team for this project as we could see that they had the necessary experience to complete the project in the necessary timescales. We were very confident that LS telcom together with VVA would deliver the quality and quantity of data we needed to inform our decisions for new regulations on the use of the 470-790 MHz frequency band in the EU.”

LS telcom and VVA examined different technical options for continuing DTT services without the 700 MHz band and concluded that without detailed multi-lateral negotiations between neighbouring EU countries, there was virtually no likelihood that existing services could be accommodated in the remaining UHF spectrum. Instead, the LS telcom and VVA study team proposed a move of all EU countries to the use of the DVB-T2 standard using either MPEG-4 or HEVC video encoding and calculated the associated costs.

From a consumer perspective the move to a new standard requires the replacement of any non-compliant set-top boxes.  Some countries are already using DVB-T2/MPEG-4 and many television receivers being sold already have this capability. Therefore, the costs of replacing the remaining non-compliant receivers are heavily dependent upon the timing of any change over.

Notwithstanding the above, the social and economic impact on the broadcasting industry was also considered.  The implementation of a policy which provides security of tenure for broadcasting services in the UHF band has definite benefits for the industry and would continue to encourage innovation.  The option that spectrum could be used in a flexible way, either for broadcasting or wireless broadband services, if carefully defined (e.g. through a CEPT report) may offer broadcasters further benefits in being able to integrate broadcasting and broadband services into the same spectrum.

The impact on PMSE services using the UHF band was also assessed.  In any of the options under consideration, some PMSE uses (e.g. radio microphones and in-ear monitors) would be displaced and require updated equipment.  The social and economic impact to the PMSE industry could be mitigated to a large extent, if alternative spectrum can be found for their continued operation.

For the wireless broadband industry, all of the options open up the 700 MHz band for new services across the EU, providing the opportunity for services with wide area coverage.

“As a leading supplier of products and services enabling greater spectrum efficiency, it is a natural step for LS telcom to join the 5GIC. Our membership will solidify our company’s integration into the 5G ecosystem and underpins our effort to always stay at the forefront of latest technology. We look forward to collaborating with the 5GIC to help define and develop the next generation of mobile and wireless communications,” confirmed Richard Womersley, Director of Spectrum Consulting at LS telcom.

As an ITU sector member LS telcom was present with a stand throughout the four weeks of the World Radiocommunica­tion Conference 2015. A team of LS telcom experts, two of them were part of the German Delegation, attended the confe­rence. Around 3300 partici­pants from 162 countries (out of ITU’s 193 Member States) atten­ded the 2015 conference to review and revise the Radio Regulations. Some 500 partici­pants representing 130 other entities, including industry, also attended the conference as observers.*


IMT Spectrum

LS telcom helped inform evidence-based decision making at the WRC through its extensive studies and analyses on the licensing and usage of worldwide international mobile telecommunications (IMT) spectrum and the ITU model for the forecast of IMT spectrum demand.

WRC-15 allocated and identified IMT globally harmonized bands in the UHF and L- (1427-1518 MHz) bands, while fully protecting the other services currently operated in these bands. “WRC-15 took a key decision that will provide enhanced capacity for mobile broadband in the 694-790 MHz frequency band in ITU Region-1 (Europe, Africa, the Middle East and Central Asia) and a globally harmo­nized solution for the implementa­tion of the digital dividend. Full protection has been given to televi­sion broadcasting as well as to the aeronautical radio navigation systems operating in this frequency band.”*

LS telcom has extensive experience in assuring interference-free co-existence of all services in these bands. Our experts have worked with a number of countries to calculate the potential impact that new LTE networks will have on DTT services and they can iden­tify the optimum mitigation tech­niques and assist regulators in set­ting LTE license conditions.



WRC-15 also laid the first milestone towards establishing the roadmap for the development of 5G mobile or IMT-2020.

LS telcom experts help institutional, academic, commercial and regula­tory organizations answer funda­mental questions around 5G: How will 5G impact spectrum demand? Will 5G be a new technology (and air-interface) or will it be a system of different technologies each playing to their own strengths? Our consult-ants have carried out numerous spectrum demand studies and can model and shed light on how growth in data demand impacts upon demand for radio spectrum. We provide spectrum demand studies, sharing studies and independent reviews of existing studies and fore­casts. Also check out our training courses on 5G which provide you with the necessary skills to critically scrutinize conflicting statements and views by different parties involved



WRC-15 identified spectrum in the 694-894 MHz frequency band to facilitate mobile broadband commu­nications for robust and reliable mission critical emergency services in public protection and disaster relief (PPDR), such as police, fire, ambulances and disaster response teams.* The development of user scenarios, the determination of capacity and spectrum require­ments, the selection of the most appropriate technology and the design and procurement of networks is where LS telcom’s expertise can support organizations with the move to new PPDR networks and technolo­gies.

Algeria Telecom selected LS telcom’s CHIRplus_FX (CHIRplus_TC) software for the planning and engineering of its microwave network.

After a rigorous international consul­tation of several renowned software tools for microwave planning, Algeria Telecom decided in favor of CHIR­plus_FX because of its robustness, its advanced technical features and its ergonomic user interface.

The leading operator in the Algerian market acquired CHIRplus_FX to industrialize its microwave network planning studies and to be able to increase productivity and efficiency, particularly in a context of rapidly evolving mobile technology and the advent of 4G which requires the deployment of an ever-important microwave network.

The software delivery comes along with theoretical and practical training to ensure the best use of the software. The training will take place in Algeria. Algeria Telecom is the incumbent operator in Algeria, which offers fixed, mobile and internet ser­vices as well as satellite communica­tions.

LS telcom is working for the European Railway Agency (ERA) on a study to analyze the possibility of using the ER/R-GSM spectrum by other radio com­munication systems for railway use in coexistence with the existing GSM-R system opera­ted in that frequency band.

Sharing the ER/R-GSM bands with a new radio communication techno­logy will possibly impact both the operation of the GSM-R-System and the additional radio system. There­fore a careful analysis of the effects, their impact on the existing GSM-R system and possible mitigation methods are required. The over-arching scope of the study can thus be summarized by the following question: Can the new system share the ER/R-GSM band or is new spectrum needed?

Depending on the answer to this question ERA may need to take further steps and the results of the study may be used by ERA to inform the Commission and the European Communication Committee about future spectrum needs for a successor to GSM-R.

LS telcom carries out EMF (electromagnetic field) studies and compliance surveys for Ericsson in South Africa.

The study consists of EMF simulations, which form the main input into the Site Safety Compliance Report according to the ICNIRP (International Commission on Non-Ionizing Radiation Protection) standard.

LS telcom assesses all types of sites, such as indoor and outdoor, rooftop and greenfield sites. Since Septem­ber 2015, LS telcom has already exa­mined 125 sites across South Africa. The compliance report covers exclu­sion zones and recommendations for appropriate signage and access con­trol to sites to ensure protection against over exposure. For sites initially not-compliant, LS telcom experts will give recommendations on measures to be taken to make the sites compliant. All sites are then re-assessed for compliancy.

ARCOTEL (Agency for the Regulation and Control of Telecommunications), the new regulatory authority of Ecua­dor, formed through the merger of Ecuador’s two former bodies SENA­TEL (Regulation) and SUPERTEL (Control), is taking over and using the LS telcom SPECTRA system that has been in operation at SENATEL since 2009. ARCOTEL has also signed a maintenance contract for the system.

Since the newly formed regulatory authority will also be responsible for regulating broadcasting services, ARCOTEL has extended the system with LS telcom’s broadcast network planning and coordination tool suite CHIRplus_BC. In addition to the software delivery, LS telcom carries out the broadcast legacy data migra­tion into SPECTRAplus_DB and gives user training.

Telenor Broadcast Norkring AS, Norway, a long-standing customer of LS telcom using CHIRplus_BC for many years, has carried out an extensive technical and commercial benchmark of standard broad­cast network planning software.

After the benchmark Norkring extends its trust to the winner of the benchmark, LS telcom, and continues to use CHIRplus_BC for the planning of its nationwide DTT, DAB and FM services in Norway as well as various other countries Norkring is operating in. Telenor Norkring engineers join training courses on broad­cast network technology and software at the LS Training Academy on a regular basis. The new contract signed by Norkring extends over several years and includes the soft­ware, a license server, upgraded propagation models as well as on-site support and commissioning. Norkring is the leading provider of terrestrial broadcasting services in Norway and operates one of the largest networks in Europe. The company is the owner of 48 main transmitter sites and approximately 1750 smaller sites spread through-out Norway.

As an additional step forward in their internal spectrum management process optimization, SUTEL has
acquired LS telcom’s Wizard Workflow Configuration Tool to be added to the technical analysis module SPECTRAemc to automate, and therefore increase the efficiency of the frequency assignment processes for land mobile and fixed services.  
SUTEL has carried out a remarkable task bringing up to date its national frequency user data base using its integrated Spectrum Management and Monitoring System, delivered and put into operation at SUTEL’s headquarters in San José by
LS telcom and Rohde & Schwarz respectively in August 2014. Now with a complete and precise database, SUTEL will be using the Wizard Configuration Tool to harmonize and automate its daily technical analyses calculations to assign new frequencies to its users. The project scope comprises the Wizard Configuration Tool knowledge transfer to SUTEL users, and the development of the first two wizards for land mobile and fixed services. The completion of the project is scheduled for December 2015. Once the knowledge transfer is complete, SUTEL users will be proficient in developing new wizards on their own as their requirements evolve.

Planning DVB-T2: Advance and Challenge

A common request amongst regulators is to provide an evaluation of the amount of spectrum required for commercial terrestrial mobile broadband (IMT) services. In trying to assess the demand for spectrum for IMT services, we have examined the model used by many regulators around the world to produce the forecasts which will eventually be used to inform decisions at World Radiocommunication Conferences (WRC). Using this model, developed by the International Telecommunications Union (ITU), we have identified a number of issues which mean that the model, as it stands, does not provide useable nor useful results.
