Recommended Separation Distances

Recommended Separation Distance Between Portable and Mobile RF
Communication Equipment and the ME Equipment
The ME Equipment is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the ME
Equipment can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment
(transmitters) and the ME Equipment as recommended below, according to the
maximum output power of the communication 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 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.
