Wireless / Telecommunication
Transmission installations on towers and roofs, and also mobile radio equipment, Pager, PCS (Personal Communication System), SMR (Specialised Mobile Radio) and 2-Way Radio (USA) are regarded as radiation sources.
In the near field area, E- and H-fields must be measured separately. Several antennas situated close together often emit different frequencies. Shaped probes make measurement considerably easier.
30 MHz ... 6 GHz
In most cases, there are low loads caused by field strengths.
400 MHz ...6 GHz, base station coupled via radio relay systems up to 40 GHz
