Recommended Separation Distances Between Portable and
Mobile RF Communications Equipment and the System
You can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communi-
cations equipment (transmitters) and the System, as recommended below, according to the maximum output power of the com-
munications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distances 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 struc-
tures, objects, and people.
