watts (W) according to the
transmitter manufacturer and
d
is
the recommended separation
distance in metres (m).

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 equipment is used exceeds the applicable RF
compliance level above, the equipment should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the equipment.
2
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
