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.
Note: At 80 MHz and 800 MHz, the separation distance for 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.
