For transmitters rated at a maximum output power not listed above, the recommended
separation distance
d
in meters (m) can be determined using the formula applicable to the
frequency of the transmitter, where
P
is the maximum rated output power of the
transmitter in watts (W) provided by the transmitter's manufacturer.
Note 1: At 80 MHz and 800 MHz, the formula used for higher frequency range applies.
Note 2: These guidances may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and human bodies.
