Recommended Separation Distances Between
Portable and Mobile RF Communications Equipment and The Product
The product is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the product can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the product
as recommended below, according to the maximum output power of the communications
equipment.
Rated maximum
output power (W) of
transmitter
Separation distance, in meters according to frequency of transmitter
150 kHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2.5 GHz
0.01 0.12 0.12 0.23
0.1 0.38 0.38 0.73
1 1.2 1.2 2.3
10 3.8 3.8 7.3
100 12 12 23
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 separation distance for the higher frequency range applies.
NOTE 2 : These guidelines may not apply in all situations. Electromagnetic propagation is afj ected by
absorption and reflection from structures, objects and people.
