Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey a
should be less than the compliance level in each
frequency range b
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a)
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 FloPatch FP120 is used
exceeds the applicable RF compliance level above, the FloPatch FP120 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the FloPatch FP120
b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
