Recommended separation distances between portable and mobile
RF communications equipment and screening system
The system is 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.

Notes:
1. At 80 MHz and 800 MHz, the separation distance for the higher frequency range is applied.
2. These guidelines are not applied in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
3. For transmitters rated at a maximum output power not listed above, the recommended separation distance
d
in meters (m) can be determined using the equation applicable to the frequency of the transmitter, where
Р
is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
