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
metres(m).b Field strengths from fixed
RF transmitters, as determined by an
electromagnetic site survey,a should
be less than the compliance level in
each frequency range.b interference
