For transmitters rated at a maximum output power not listed above, the recommended separation
distances 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 1: E1) At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
Note 2: E2) These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
