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 metres (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 Q-spo-wu1 is used exceeds
the applicable RF compliance level above, the Q-spo-wu1 should be observed to
verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the Q-spo-wu1.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m.
