EMC Tables
Recommended separation distances between
portable and mobile RF communications equipment and the product
The product is intended for use in an electromagne c environment in which radiated RF disturbances are
controlled. The customer or the user of the product can help prevent electromagne c interference by
maintaining a minimum distance between portable and mobile RF communica ons equipment (transmi ers)
and the product as recommended below, according to the maximum output power of the communica ons
equipment.
Rated maximum output
power (W) of transmitter
Separation distance, in meters according to frequency of transmitter
150 kHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2. 7 GHz
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 transmi ers rated at a maximum output power not listed above, the recommended separa on distance d
in meters (m) can be es mated using the equa on applicable to the frequency of the transmi er, where P is
the maximum output power ra ng of the transmi er in wa s (W) according to the transmi er manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separa on distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situa ons. Electromagne c propaga on is affected by absorp on
and reflec on from structures, objects and people.
