For transmitters rated at a maximum output power not listed above, the recommended separation distance “d” in meters
(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.
