9.3. OUT OF BAND EMISSIONS
RULE PART(S)
FCC: §2.1051, §22.901, §22.917, §24.238, §27.53 and §90.543

LIMITS
The power of any emission outside of the authorized operating frequency ranges must be attenuated
below the transmitting power (P) by a factor of at least 43 + 10 log (P) dB.

Part 27.53:
(a)(4) For mobile and portable stations operating in the 2305-2315 MHz and 2350-2360 MHz bands:
(i) By a factor of not less than: 43 + 10 log (P) dB on all frequencies between 2305 and 2320 MHz and
on all frequencies between 2345 and 2360 MHz that are outside the licensed band(s) of operation, not
less than 55 + 10 log (P) dB on all frequencies between 2320 and 2324 MHz and on all frequencies
between 2341 and 2345 MHz, not less than 61 + 10 log (P) dB on all frequencies between 2324 and
2328 MHz and on all frequencies between 2337 and 2341 MHz, and not less than 67 + 10 log (P) dB
on all frequencies between 2328 and 2337 MHz;
(ii) By a factor of not less than 43 + 10 log (P) dB on all frequencies between 2300 and 2305 MHz, 55 +
10 log (P) dB on all frequencies between 2296 and 2300 MHz, 61 + 10 log (P) dB on all frequencies
between 2292 and 2296 MHz, 67 + 10 log (P) dB on all frequencies between 2288 and 2292 MHz,
and 70 + 10 log (P) dB below 2288 MHz;
(iii) By a factor of not less than 43 + 10 log (P) dB on all frequencies between 2360 and 2365 MHz, and
not less than 70 + 10 log (P) dB above 2365 MHz.

(c)(2) On any frequency outside the 776-788 MHz band, the power of any emission shall be attenuated
outside the band below the transmitter power (P) by at least 43 + 10 log (P) dB.

(g) For operations in the 600 MHz band and the 698-746 MHz band, the power of any emission outside a
licensee's frequency band(s) of operation shall be attenuated below the transmitter power (P) within the
licensed band(s) of operation, measured in watts, by at least 43 + 10 log (P) dB. Compliance with this
provision is based on the use of measurement instrumentation employing a resolution bandwidth of 100
kilohertz or greater. However, in the 100 kilohertz bands immediately outside and adjacent to a licensee's
frequency block, a resolution bandwidth of at least 30 kHz may be employed.

(h) The power of any emission outside a licensee's frequency block shall be attenuated below the
transmitter power (P) in watts by at least 43 + 10 log10 (P) dB.

(m)(4) For mobile station, the attenuation factor shall be not less than 43 + 10 log (P) dB at the channel
edge and (55 + 10 log (P)dB) at the 5.5 MHz from the channel edges.

(f) For operations in the 746-758 MHz, 775-788 MHz, and 805-806 MHz bands, emissions in the band
1559-1610 MHz shall be limited to −70 dBW/MHz equivalent isotropically radiated power (EIRP) for
wideband signals, and −80 dBW EIRP for discrete emissions of less than 700 Hz bandwidth. For the
purpose of equipment authorization, a transmitter shall be tested with an antenna that is representative of
the type that will be used with the equipment in normal operation. (Band 13)

Part 90.543:
(c) Out-of-band emission limit. On any frequency outside of the frequency ranges covered by the ACP
tables in this section, the power of any emission must be reduced below the mean output power (P) by at
least 43 + 10log (P) dB measured in a 100 kHz bandwidth for frequencies less than 1 GHz, and in a 1
MHz bandwidth for frequencies greater than 1 GHz.

(e)(2) On all frequencies between 769-775 MHz and 799-805 MHz, by a factor not less than 65 + 10 log
(P) dB in a 6.25 kHz band segment, for mobile and portable stations.

Part 90.691(a):
(1) For any frequency removed from the EA licensee's frequency block by up to and including 37.5 kHz,
the power of any emission shall be attenuated below the transmitter power (P) in watts by at least 116
Log10(f/6.1) decibels or 50 + 10 Log10(P) decibels or 80 decibels, whichever is the lesser attenuation,
where f is the frequency removed from the center of the outer channel in the block in kilohertz and where
f is greater than 12.5 kHz.

(2) For any frequency removed from the EA licensee's frequency block greater than 37.5 kHz, the power
of any emission shall be attenuated below the transmitter power (P) in watts by at least 43 + 10Log10(P)
decibels or 80 decibels, whichever is the lesser attenuation, where f is the frequency removed from the
center of the outer channel in the block in kilohertz and where f is greater than 37.5 kHz.(NOTE : Use
100kHz reference bandwidth)

(b) When an emission outside of the authorized bandwidth causes harmful interference, the Commission
may, at its discretion, require greater attenuation than specified in this section.

TEST PROCEDURE
Per KDB 971168 D01 Power Meas License Digital Systems v03r01
The RF output of the transmitter was connected to a spectrum analyzer through a calibrated coaxial
cable. Sufficient scans were taken to show the out-of-band Emissions, if any, up to 10th harmonic.
Multiple sweeps were recorded in maximum hold mode using a peak detector to ensure that the worst-
case emissions were caught.

a) Set the RBW = 100KHz for emission below 1GHz and 1MHz for emissions above 1GHz
(Tests were performed 1MHz [Worst case], to sweep 1 time for all frequency range)

b) Set VBW ≥ 3 × RBW;

c) Set span ≥ 1.5 times the OBW;

d) Sweep time = auto couple;

e) Detector = rms;

f) Ensure that the number of measurement points = Max (40001);

g) Trace mode = average(WCDMA, LTE), Maxhold(GSM, LTE Band 40, 41);

Note : Please refer to section 5.4 for bandwidth and RB setting about LTE bands.
