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 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 .
