applicable to the frequency of the
transmitter.
Recommended separation distance
d = 1.2P
d = 1.2P 80 MHz to 800 MHz
d = 2.3P 800 MHz to 2.7 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
meters (m).

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.
a
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 REAL System 2 is used
exceeds the applicable RF compliance level above, REAL System 2 should be observed to verify normal
