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

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).
