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.
