then make sure to
maintain the
separation greater
than the
recommended
separation calculated
based on the
transmission frequency
applied at every part
of the product
including the cable.
d = 1.2 √P
d = 1.2 √P 80MHz to
800MHz

P stands for the max
rated output power of
transmitter (W), which
is designated by the
transmitter
manufacturer, d is the
recommended
separation expressed
in the unit of meter
(m).
The electromagnetic
field strength for a
fixed RF transmitter is
determined by the on-
site investigations of
the electromagnetic
fields, but with regard
to Remark 3.1, it
should be ideally
below the level set in
each frequency band.
