For transmitters rated at maximum output power not
listed above, the recommended separation distances (d)
in meters (m) can be estimated using the equation ap-
plicable to the frequency of the transmitter, where (P) is
the maximum output power rating of the transmitter in
watts (W) according to transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation dis-
tance for the higher frequencyrange applies.
NOTE 2 These guidelines may not apply in all situ-
ations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and
people.
