Recommended separation distance between portable and mobile RF communication equipment
and AKR550
AKR550 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of AKR550 can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communication equipment (transmitters) and AKR550
are 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)
150kHz to 80MHz
d= 1.2 √P
80MHz to 800MHz
d= 1.2 √P
800MHz to 2.5GHz
d= 2.3 √P
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 affected by
absorption and reflection from structures, objects and people.
