For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the equa-
tion 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.
