Note:Per ANSI C63.10-2013 Section 14.3.2.2 and KDB 662911 v02r01 Section E)2), the power spectral density at
Antenna 1 and Antenna 2 were first measured separately as shown in the section above. The measured values
were then summed in linear power units then converted back to dBm.
Per ANSI C63.10-2013 Section 14.4.3, the directional gain is calculated using the following formula, where GN is
the gain of the nth antenna and NANT, the total number of antennas used.

Sample MIMO Calculation:
At 5935MHz in 802.11ax (20MHz BW) mode, the average conducted power spectral density was measured to be-3.56 dBm for Antenna-1 and -3.49 dBm for Antenna-2.
Antenna 1 + Antenna 2 = MIMO(-3.56 dBm + -3.49 dBm) = (.441 mW + .448 mW) = .889 mW = -0.52 dBm
Sample e.i.r.p Power Spectral Density Calculation:
At 5935 MHz in 802.11ax (20MHz BW) mode, the average MIMO power density was calculated to be -0.52 dBmwith directional gain of -0.61 dBi.
e.i.r.p. Power Spectral Density(dBm) = Power Spectral Density (dBm) + Ant gain (dBi)-0.52 dBm + -0.61 dBi = -1.13 dBm

7.5

In-Band Emissions – 802.11ax§15.407(b)(6)

Test Overview and Limit
The spectrum analyzer was connected to the antenna terminal while the EUT was operating at its maximum duty
cycle, at its maximum power control level, as defined in ANSI C63.10-2013 and KDB 789033 D02 v02r01, and at
the appropriate frequencies.
For transmitters operating within the 5.925-7.125 GHz bands: Power spectral density must be suppressedby 20 dB at 1 MHz outside of channel edge, by 28 dB at one channel bandwidth from the channel center,and by 40 dB at one- and one-half times the channel bandwidth away from channel center. At frequencies
between one megahertz outside an unlicensed device's channel edge and one channel bandwidth fromthe center of the channel, the limits must be linearly interpolated between 20 dB and 28 dB suppression,and at frequencies between one and one- and one-half times an unlicensed device's channel bandwidth,
the limits must be linearly interpolated between 28 dB and 40 dB suppression. Emissions removed fromthe channel center by more than one- and one-half times the channel bandwidth must be suppressed byat least 40 dB.
Test Procedure Used
ANSI C63.10-2013 – Section 12.3.2.2
KDB 987594 D02 v01r01
Test Settings
1.

Connect output of the antenna port to a spectrum analyzer or EMI receiver, with appropriate attenuation, as
to not damage the instrumentation.
2. Set the reference level of the measuring equipment in accordance with procedure 4.1.5.2 of ANSI C63.102013.
3. Measure the 26 dB EBW using the test procedure 12.4.1 of ANSI C63.10-2013. (This will be used todetermine the channel edge.)
4. Measure the power spectral density (which will be used for emissions mask reference) using the following
procedure:a)
Set the span to encompass the entire 26 dB EBW of the signal.
b)
Set RBW = same RBW used for 26 dB EBW measurement.
c)
Set VBW ≥ 3 X RBWd)
Number of points in sweep ≥ [2 X span / RBW].
e)
Sweep time = auto.
f)
Detector = RMS (i.e., power averaging)g)Trace average at least 100 traces in power averaging (rms) mode.
h)
Use the peak search function on the instrument to find the peak of the spectrum.
5. For the purposes of developing the emission mask, the channel bandwidth is defined as the 26 dB EBW.
6. Using the measuring equipment limit line function, develop the emissions mask based on the following
requirements. The emissions power spectral density must be reduced below the peak power spectral
density (in dB) as follows:a)Suppressed by 20 dB at 1 MHz outside of the channel edge. (The channel edge is defined as
the 26-dB point on either side of the carrier center frequency.)b)
Suppressed by 28 dB at one channel bandwidth from the channel center.
c)
Suppressed by 40 dB at one- and one-half times the channel bandwidth from the channel
center.
7. Adjust the span to encompass the entire mask as necessary.
8. Clear trace.
9. Trace average at least 100 traces in power averaging (rms) mode.
10. Adjust the reference level as necessary so that the crest of the channel touches the top of the emission
mask.
