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: From 80MHz to 800MHz, 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.
