Recommended Separation Distances for between
Portable and Mobile RF Communications Equipment and the Xcel 255
The Xcel 255 is intended for use in the electromagnetic environment in which radiated RF distur-
bances are controlled. The customer or user of the Xcel 255 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF Communi-
cations Equipment (transmitters) and the Xcel 255 as recommended below, according to the
maximum output power of the communications equipment.
Max Output Power
of Transmitter
(W)
Separation (m)
150kHz to 80 MHz
d=(3.5/v1)(Sqrt P)
Separation (m)
80 to 800 MHz
d=(3.5/E1)(Sqrt P)
Separation (m)
800MHz to 2.5GHz
d=(7/E1)(Sqrt P)
0.01 0.1166 0.1166 0.2333
0.1 0.3689 0.3689 0.7378
1 1.1666 1.1666 2.3333
10 3.6893 3.6893 7.3786
100 11.6666 11.6666 23.3333
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 reflection from structures, objects, and people.
