For transmitters whose maximum nominal output is not specified in the
above table, the recommended working clearance d in meters (m) can be
determined using the equation in the corresponding column, where P is
the maximum nominal output of the transmitter in watts (W) specified by
the manufacturer of the.
Remark 1
The higher frequency range applies at 80 MHz and 800 MHz.
Remark 2
These guidelines may not be applicable in all cases. The propagation of
electromagnetic waves is influenced by their absorption and reflection by
buildings, objects and persons.
