TABLE 4

Recommended separation distances between portable and mobile RF communications equipment and

device

The device is intended for use in an electromagnetic environment in which radiated RF disturbances

are controlled. The customer or the user of device can help prevent electromagnetic interference

by maintaining a minimum distance between portable and mobile RF communications equipment

(transmitters) and device, 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

0.15 MHz to 80 MHz

d=1.2√P

80 MHz to 800 MHz

d=1.2√P

80 MHz to 2.7 GHz

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 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.
