ELECTROMAGNETIC COMPATIBILTY (EMC)

Recommended Separation Distances Between Portable and Mobile RF Communications

Equipment and the Equipment

The equipment is intended for use in the electromagnetic environment in which radiated RF disturbances are

controlled. The customer or the user of the equipment can help to prevent electromagnetic interference by

maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)

and the equipment as recommended in the table 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 800 MHz 800 MHz to 2.7 GHz

d = 1.2 P d = 2.3 P

0.01 0.1 m 0.2 m

0.1 0.4 m 0.7 m

1 1.2 m 2.3 m

10 4.0 m 7.0 m

100 12.0 m 23.0 m

For transmitters rated at a maximum output power not listed above, the recommended separation distance

in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where

the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.

NOTE 1: At 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 the

absorption and reflection from structures, objects, and people.
