E.2. and KDB 66291 D01. Please see associated annex for details on instrument settings. The maximum average RF conducted output power measured for this device was 27.81 dBm or 604 mW. The limit is 30 dBm, or 1 Watt when using antennas with 6 dBi or less gain. The antenna has a gain of 8 dBi however, the measured conducted output power is below an adjusted 28.0 dBm or 0.63 watts limit.

The graphs show the measurement data from spurious emissions noted across the frequency range when transmitting at the lowest frequency, middle frequency and upper frequency. Shown within the annex are plots with the EUT turned to the upper and lower channels with the antenna gain of 8 dBi accounted for. These demonstrate compliance with the provisions of this section at the band edges. 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. Result Conducted spurious emissions were attenuated below the limit; therefore, the EUT complies with the specification. 5.5.2 Radiated Spurious Emissions in the Restricted Bands of § 15.205 The EUT uses various power settings based on the channel in use. In order to reduce test time, the radiated spurious emissions at the lowest, middle, and highest channel were measured at the maximum power of TP55. Correction Factor = Antenna Factor + Cable Loss - Pre-Amplifier Gain, and is added to the Receiver reading. Result All emissions in the restricted bands of § 15.205 met the limits specified in § 15.209; therefore, the EUT complies with the specification. See Annex for Conducted Band edge plots.

F. and KDB 66291 D01. Please see associated annex for details on instrument settings. The maximum average power spectral density conducted from the intentional radiator of the antenna shall not be greater than 30 dBm in any 500 kHz band during any time interval of continuous transmission. Results of this testing are summarized. As per KDB 662911, When the EUT is using spatial-multiplexing in HE modes, there is not additional array gain to accommodate. When the EUT uses Nss=1 data rates, the antenna gain is 8 dBi + Array gain of 3.01 dB which is a total of 11.01 dBi Modulation Frequency (BW) (MHz) Data Rate OFDM 20 OFDM 20 OFDM 20 HE 20 HE 20 HE 20 HE 40 HE 40 HE 40 HE 80 5745 5775 5825 5745 5775 5825 5755 5775 5795 5775 Mcs0 Mcs0 Mcs0 Mcs0 Mcs0 Mcs0 Mcs0 Mcs0 Mcs0 Mcs0 TP Setting 50 52 52 50 52 52 50 52 52 48 Conducted Output Power 26.44 27.81 27.80 26.04 27.71 27.71 26.49 27.60 27.56 25.42 Measured Measured EIRP PSD 34.44 35.81 35.80 34.04 35.71 35.71 34.49 35.60 35.56 33.42 10 16 11.03 9.21 10.65 10.30 6.92 7.77 7.87 3.31 Result The maximum summed average power spectral density was less than the limit of 30 dBm; therefore, the EUT complies with the specification.
