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 metres (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
Interference may occur in the vicinity
of equipment marked with the
following symbol:
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 [ME EQUIPMENT or ME SYSTEM] exceeds the applicable RF compli-
ance level above, the [ME EQUIPMENT or ME 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 [ME EQUIPMENT or ME SYSTEM].
b
Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
