Recommended separation distances between portable and mobile RF communications
equipment and the equipment or system - for equipement and systems that are not
-
life-supporting. The model BW-CX10 is intended for use in an electromagnetic environ-
r
ment in which radiated RF disturbances are controlled. The customer or the user of the
model BW-CX10 can help prevent electromagnetic interference by maintaining a mini-
mum distance between portable and mobile RF communications equipment (transmit-
ters) and the model BW-CX10 as recommended below, according to the maximum output
power of the communications equipment.
Rated maximum output
of transmitter
For transmitters rates 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 transmit-
ter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800MHz, the reparation distance for the higher frequency range
s
applies.
NOTE 2 these guidelines may not apply in all situations. Electromagnetic propagation is
-
affected by absorption and reflection from structures, objects and people.
