than the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
d=1.2 P
d=1.2 P 80MHz to 800MHz
d=2.3 P 800MHz to 2.5 Ghz
where P is the maximum output
power rating of the transmitter in
watts (W) 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

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 predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which the
is used exceeds the applicable RF compliance level above,
the should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or
relocating the
