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
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
.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than 3 V/m.
