Electromagnetic environment -
guidance
Portable and mobile RF communications
equipment should be used no closer to
any part of the generator, including
cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance
d=1.2√ P
d=1.2√P 80 MHz to 800 MHz
d=2.3√P 800 MHz to 2.5 GHz
Where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter
manufacturer and d is the recommended
separation distance in meters (m).
Field strengths from fixed RF

transmitters , as determined by an
electromagnetic site survey, should be
