Recommended sepa-
ration distances
between portable and
mobile RF communi-
cations equipment
and the Mobilett XP
The Mobilett XP is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Mobilett
XP can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmit-
ters) and the Mobilett XP 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]
150 kHz to 80 MHz
d = 1.2 x ( P )
(1/2)
80 MHz to 800 MHz
d = 1.2 x ( P )
(1/2)
800 MHz to 2,5 GHz
d = 2.3 x ( P )
(1/2)
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 manufac-
turer.
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 absorp-
tion and reflection from structures, objects and people.
