7.9 Radiated Emissions which fall in the restricted bands
Test Requirement 47 CFR Part 15, Subpart C 15.209 & 15.407(b)
Test Method: KDB 789033 D02 II G
Limit:
Frequency(MHz) Field strength(microvolts/meter)

0.009-0.490 2400/F(kHz) 300
0.490-1.705 24000/F(kHz) 30
1.705-30.0 30 30

*(1) For transmitters operating in the 5.15-5.25 GHz band: All emissions outside of the 5.15-
5.35 GHz band shall not exceed an e.i.r.p. of −27 dBm/MHz.
(2) For transmitters operating in the 5.25-5.35 GHz band: All emissions outside of the 5.15-5.35
GHz band shall not exceed an e.i.r.p. of −27 dBm/MHz.
(3) For transmitters operating in the 5.47-5.725 GHz band: All emissions outside of the 5.47-
5.725 GHz band shall not exceed an e.i.r.p. of −27 dBm/MHz.
(4) For transmitters operating in the 5.725-5.85 GHz band:
(i) All emissions shall be limited to a level of −27 dBm/MHz at 75 MHz or more above or below
the band edge increasing linearly to 10 dBm/MHz at 25 MHz above or below the band edge,
and from 25 MHz above or below the band edge increasing linearly to a level of 15.6
dBm/MHz at 5 MHz above or below the band edge, and from 5 MHz above or below the band
edge increasing linearly to a level of 27 dBm/MHz at the band edge.
Remark: The emission limits shown in the above table are based on measurements employing
a CISPR quasi-peak detector except for the frequency bands 9-90kHz, 110-490kHz and above
1000 MHz. Radiated emission limits in these three bands are based on measurements
employing an average detector, the peak field strength of any emission shall not exceed the
maximum permitted average limits specified above by more than 20 dB under any condition of
modulation.
