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 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.
