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, and
electromagnetic site survey should be considered. If the measured field strength in
the location in which the GPS is used exceeds the applicable RF compliance level
above, the GPS should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting
or relocation the GPS.
b
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than
3 V/m.
