where Pis 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.

NOTE 1.
NOTE 2.
At 80 MHz and 800 MHz, the higher frequency range applies.
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 andTV
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
is used exceeds the applicable RF compliance level above, the
should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
