1)
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which the
system is used exceeds the applicable RF compliance level above, the system should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the system.
2)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
3)
Ensured by PC compliance with IEC 61000-4-6 requirements.
Notes:
1. At 80 MHz and 800 MHz, the higher frequency range is applied.
2. These guidelines are not applied in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
