than the recommended sep-
aration distance calculated from
the equation applicable to the
frequency of the transmitter.
Recommended separation
distance:
d = 1.2√ P 150 KHz to 80 MHz
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 watt (W)
according to the transmitter
manufacturer, and is the
recommended separtion
distance in meters (m).
Field strengths from fixed RF
transmitters, as determined
by an electromagnetic site
survey, should be less than
the compliance level in each
frequency range.
