Field strengths from fixed RF
transmitters, as determined
by an electromagnetic site
survey, (a) 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.
(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 the GSI 39 is used exceeds the applicable RF compliance level
