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.

Power frequency magnetic fields should be
that of a typical location in a typical
commercial or hospital environment.
Portable and mobile RF communications
equipment should be separated from the
device by no less than the recommended
separation distances calculated/listed
below:
√
D=(3.5/V1)
P
√ 80 to 800 MHz
D=(3.5/E1)
P
800 MHz to 2.5 GHz
√
D=(7/E1) P
Where P is the maximum power rating in
watts and D is the recommended
separation distance in meters.
Field strengths from fixed transmitters, as
determined by an electromagnetic site
survey, should be less than the compliance
levels (V1 and E1).
Interference may occur in the vicinity of
equipment containing a transmitter.
