For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in 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 800 MHz, the separation distance for the higher frequency range
applies.
Note 2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
