Electromagnetic environment –
guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the System, including cables, than
the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d = 1,17 √ P
d = 1,17 √ P 80 MHz to 800 MHz
d = 2,33 √ P 800 MHz 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 meters (m).
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 System is used
exceeds the applicable RF compliance level above, the System should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the System.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
