Recommended Separation Distances Between Portable and Mobile RF Communications
Equipment and the Crossre™ System
The Crossre™ System is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The user of the Crossre™ System can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Crossre™ System as recommended below, according to the
maximum output power of the communications equipment.
Rated maximum
output power (W) of
transmitter
Separation distance (m) 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 0.37 0.37 0.74
1 1.17 1.17 3.70
10 3.70 2.33 7.37
100 11.70 11.70 23.30
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 affected by absorption and
reection from structures, objects, and people.
