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: These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
