Where P is the maximum
output power rating of the
transmitter In watts (W)
according to the. Transmitter
manufacturer and d is the
recommended separation
distance in meters (m).
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 I. At 80 MHz and 800 MHz. the separation distance for the higher
frequency range applies.
NOTE 2. These guidelines may not apply in all situations. Electro-
magnetic 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 device is
used exceeds the applicable RF compliance level above, should
be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as
reorienting or relocating the device.
b
Over the frequency range 150 kHz to 80 MHz, field strengths
should be less than [Vi] V/m
