Recommended separation distances between portable and mobile RF communications

equipment and the Guardian REAL-Time system

This section provides information on the recommended separation distance between portable and

mobile RF communications equipment and the Guardian REAL-Time. The Guardian REAL-Time is

intended for use in an electromagnetic environment in which radiated RF disturbances are

controlled. Guardian REAL-Time users can help prevent electromagnetic interference by

maintaining a minimum distance between portable and mobile RF communications equipment

(transmitters) and the Guardian REAL-Time as recommended below, according to the maximum

output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation

distance d in meters (m) can be estimated using 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.

NOTE: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.

NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is affected by

absorption and reflection from structures, objects and people.
