Recommended separation distances between
portable and mobile RF communications equipment and the device
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 seperation 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.
