Recommended separation distances between portable and mobile RF com-
munications equipment and the EQUIPMENT
The EQUIPMENT is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the EQUIP-
MENT can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmit-
ters) and the EQUIPMENT as recommended below, according to the maximum
output power of the communications equipment.
Rated maximum Separation distance according to frequency of transmitter (m)
GHz
For transmitters rated at a maximum output power not listed above, the recom-
mended 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 manufac-
turer.
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 propa-
gation is affected by absorption and reflection from structures, objects and people.
