(d) 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. (ii) Devices certified before March 2, 2017 with antenna gain greater than 10 dBi may demonstrate compliance with the emission limits in §15.247(d), but manufacturing, marketing and importing of devices certified under this alternative must cease by March 2, 2018. Devices certified before March 2, 2018 with antenna gain of 10 dBi or less may demonstrate compliance with the emission limits in §15.247(d), but manufacturing, marketing and importing of devices certified under this alternative must cease before March 2, 2020. (e) The emission measurements shall be performed using a minimum resolution bandwidth of 1 MHz. A lower resolution bandwidth may be employed near the band edge, when necessary, provided the measured energy is integrated to show the total power over 1 MHz. (f) Unwanted emissions below 1 GHz must comply with the general field strength limits set forth in §15.209. Further, any U-NII devices using an AC power line are required to comply also with the conducted limits set forth in §15.207. (g) The provisions of §15.205 apply to intentional radiators operating under this section. (h) When measuring the emission limits, the nominal carrier frequency shall be adjusted as close to the upper and lower frequency band edges as the design of the equipment permits. 5.7.2 TEST CONFIGURATION 5.7.3 TEST PROCEDURE 1. The power was monitored at the coupler port with a Spectrum Analyzer. The power level was set to the maximum level. 2. Set the RBW = 1MHz. 3. Set the VBW ≥ 3MHz 4. Number of points in sweep ≥ 2 × span / RBW. (This ensures that bin-to-bin spacing is ≤ RBW/2, so that narrowband signals are not lost between frequency bins.) 5. Manually set sweep time ≥ 10 × (number of points in sweep) × (total on/off period of the transmitted signal). 6. Set detector = power averaging (rms). 7. Sweep time = auto couple. Page 46 of 58

Report No.: HUAK180824890E3 5.8. Antenna Requirements 5.8.1. Standard Applicable For intentional device, according to FCC 47 CFR Section 15.203: An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator, the manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited And according to FCC 47 CFR Section 15.407 (a), if transmitting antennas of directional gain greater than 6dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi. 5.8.2. Antenna Connector Construction The directional gains of antenna used for transmitting refer to section 1.1 of this report , and the antenna is an internal antenna connect to PCB board and no consideration of replacement. Please see EUT photo for details. 5.8.3. Results: Compliance. Measurement The antenna gain of the complete system is calculated by the difference of radiated power in EIRP and the conducted power of the module. Conducted power refers ANSI C63.10:2013 Output power test procedure for UNII devices. Radiated power refers to ANSI C63.10:2013 Radiated emissions tests. Measurement parameters Measurement parameter Detector: Peak Sweep Time: Auto Resolution bandwidth: 1MHz Video bandwidth: 3MHz Trace-Mode: Max hold Note: The antenna gain of the complete system is calculated by the difference of radiated power in EIRP and the conducted power of the module. For 5G WLAN devices, the IEEE 802.11a mode is used. Limits FCC ISED Antenna Gain 6 dBi Page 56 of 58
