Recommended Separation Distances Between

Portable and Mobile RF Communications Equipment and the POC-W211

POC-W211 is intended for use in an electromagnetic environment in which radiated RF

disturbances are controlled. The customer or the user of the model POC-W211 can help

prevent electromagnetic interference by maintaining a minimum distance between portable

and mobile RF communications equipment (transmitters) and the model POC-W211 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 sep-

aration distance d in meters (m) can be estimated using the equation in the table above

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.
