Recommended separation distances between portable and mobile
RF communication equipment and the EQUIPMENT or SYSTEM-
For EQUIPMENT or SYSTEM that are not LIFE-SUPPORTING
Recommended separation distances between portable and mobile RF communications
equipment and the system
The system i
s intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the system
can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the system 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 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
NOTE 2:
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
