For transmitters rated at a maximum output power not listed above, the recommended separation distance
d
in metres
metres
(m) can be estimated using the equation applicable to the frequency of the transmitter, where
P
is the maximum output
power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800MHz, the separation distance for the higher frequency range applies.
NOTE 2 These quidelines may not apply in all situations. Electromagnetic propagation is affected by adsorption and
re
fl
ection from structures, objects and people.
