8.4 Recommended separation distances between portable
and mobile RF communications equipment and the EUT
Intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the EUT can help
prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters)
and the EUT 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 separation distance d
in metres (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 80MHz and 800MHz, 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.
