Recommended Separation Distances between Portable and Mobile RF Communications Equipment and the Chattanooga
Continuum
The Chattanooga Continuum is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the Chattanooga Continuum can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and
the Chattanooga Continuum as recommended below, according to the maximum output power of the communications
equipment.
Rated Maximum Output Power of
Transmitter W
Separation Distance According to Frequency of Transmitter m
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 : At  MHz and  MHz, the separation distance for the higher frequency range applies.
• NOTE : These guidelines may not apply in all situations. Electromagnetic propagation is aected by absorption
and reflection from structures, objects, and people.
