10.7 Table 5 – Recommended separation distances between
portable and mobile HF communications equipment
and the product
The product is intended for use in an electromagnetic environment in which HF disturbances
are controlled. The customer or user of the product can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile HF
communications equipment (transmitters) and the product as recommended below, according
to the output energy of the communications equipment.
Rated power of the
transmitter [W]
Separation distance d [m] according to the transmitter frequency

80MHz to 800MHz
d = 1.2√P
800MHz to 2.5GHz

For transmitters whose maximum rated power is not listed in the table above, the recom-
mended separation distance d in meters (m) can be estimated using the equation from the re-
spective column, whereby P is the maximum rated power of the transmitter in watts (W) ac-
cording to the transmitter manufacturer.
Note: At 80MHz and 800MHz, the separation distance for the higher frequency range ap-
plies.
Note: These guidelines may not apply in all situations. The propagation of electromagnetic
waves is affected by absorptions and reflections of buildings, objects, and people.
