Portable and mobile RF communications
equipment should be used no closer to
any part of the system, including cables,
than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.

(Portable RF communications
equipment (including peripherals such
as antenna cables and external
antennas) should be used no closer than
30 cm (12 inches) to any part of the
system, including cables specified by the
manufacturer).
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,
