Radio transmitters produce electromagnetic fields which members of the public may be exposed to. In order to assess people’s safety their exposure must be measured and compared with the appropriate limits. This course will focus on the measurement of general public exposure; in addition, some aspects of occupational exposure are discussed. The training will be held on classroom in LS telcom training facilities. The lecture will be supported by practical measurements of real life radio signals by nearby RF transmitters.
After completing the Online Training, delegates will be able to perform measurements of RF exposure caused by different radio services which follow the correct measurement methodology, equipment settings and post processing. They will also understand the philosophy behind the exposure limits.
This course is intended for those who have basic knowledge in RF wireless communication techniques and understanding in spectrum analyzer, who are interested in measurement of human exposure to RF electromagnetic fields and who may be employed in regulatory authorities, environmental agencies, radiation protection authorities, health and safety departments of network operators or measurement laboratories.
