outside the band below the transmitter power (P) by at least 43 + 10 log (P) dB;
(4) On all frequencies between 763-775 MHz and 793-805 MHz, by a factor not less than 65 + 10 log (P)
dB in a 6.25 kHz band segment, for mobile and portable stations;

(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.

(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) For mobile digital stations, the attenuation factor shall be not less than 40 + 10 log (P) dB on all
frequencies between the channel edge and 5 megahertz from the channel edge, 43 + 10 log (P) dB on all
frequencies between 5 megahertz and X megahertz from the channel edge, and 55 + 10 log (P) dB on all
frequencies more than X megahertz from the channel edge, where X is the greater of 6 megahertz or the
actual emission bandwidth as defined in paragraph (m)(6) of this section. In addition, the attenuation
factor shall not be less that 43 + 10 log (P) dB on all frequencies between 2490.5 MHz and 2496 MHz
and 55 + 10 log (P) dB at or below 2490.5 MHz. Mobile Satellite Service licensees operating on
frequencies below 2495 MHz may also submit a documented interference complaint against BRS
licensees operating on channel BRS Channel 1 on the same terms and conditions as adjacent channel
BRS or EBS licensees.

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) For operations in the 758-768 MHz and the 788-798 MHz bands, the power of any emission outside
the 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, in accordance with the following:

(1) On all frequencies between 769-775 MHz and 799-805 MHz, by a factor not less than 76 + 10 log
(P) dB in a 6.25 kHz band segment, for base and fixed stations.
(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.
(3) On any frequency between 775-788 MHz, above 805 MHz, and below 758 MHz, by at least 43 + 10
log (P) dB.
(4) Compliance with the provisions of paragraphs (e)(1) and (2) of this section is based on the use of
measurement instrumentation such that the reading taken with any resolution bandwidth setting
should be adjusted to indicate spectral energy in a 6.25 kHz segment.
(5) Compliance with the provisions of paragraph (e)(3) of this section is based on the use of
measurement instrumentation employing a resolution bandwidth of 100 kHz or greater. However, in
the 100 kHz bands immediately outside and adjacent to the frequency block, a resolution bandwidth
of 30 kHz may be employed.

Part 90.691:
(a) Out-of-band emission requirement shall apply only to the “outer” channels included in an EA license
and to spectrum adjacent to interior channels used by incumbent licensees. The emission limits are as
follows:

(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.

TEST PROCEDURE
Per KDB 971168 D01 Power Meas License Digital Systems v03r01
The transmitter output was connected to a CMW500 Test Set and configured to operate at maximum
power. The band edge emissions were measured at the required operating frequencies in each band on
the Spectrum Analyzer.

WCDMA/LTE

a) Set the RBW = 1 ~ 1.5 % of OBW(Typically limited to a minimum RBW of 1% of the OBW)

b) Set VBW ≥ 3 × RBW;

c) Set span ≥ 1.5 times the OBW;

d) Sweep time = Auto;

e) Detector = RMS;

f) Ensure that the number of measurement points ≥ 2*Span/RBW;

g) Trace mode = Average (100);

NOTE
1. LTE Band 41 - Duty cycle correction factor(2.25dB) already applied on the plot.
2. LTE Band 26 -
