according to the transmitter
manufacturer and d is the
recommended separation distance in
metres (m).

Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey, should be
less than the compliance level in each
frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE 1:
At 80 MHz and 800 MHz, 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.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be
