Measurement Procedures We performed the measurements in accordance with NV3-10, available upon the request. No deviation Deviation from the above procedure The summary of the above procedure is mentioned below Dynamic Frequency Selection (for Client device without radar detection) 1. As master device, Access Point AIR-CAP3702E-B-K9 (FCC ID: LDK102087) is used. 2. Master device communicates with client device (EUT) by transmitting/receiving a data packet. Applicability of DFS requirements during normal operation; Requirements for devices Client Without Radar Detection with multiple bandwidth modes Channel Move Time, Channel Closing Transmission Time, Test using the widest BW mode available for the link Non-Occupancy Period 3. Vector Signal Generator set to the Short Pulse Radar Type 0 and level of Detection Threshold + 1 dB at antenna port of the master device. Radar Test Waveform; Pulse Width PRI Number of Minimum Percentage Minimum Radar Type [μsec] [μsec] Pulses of Successful Detection Number of Trials 0 1 1428 18 - - Note : Short Pulse Radar Type 0 is used for the channel move time, and channel closing time tests. DFS Detection Thresholds for Master Devices; Maximum Transmit Power Value [dBm] EIRP ≥ 200 [mW] -64 EIRP < 200 [mW] and -62 power spectral density < 10 [dBm/MHz] EIRP < 200 [mW] that -64 do not meet the power spectral density requirement Note : This is the level at the input of the receiver assuming a 0 dBi receive antenna. Throughout these test procedures an additional 1 dB has been added to the amplitude of the test transmission waveforms to account for variations in measurement equipment. This will ensure that the test signal is at or above the detection threshold level to trigger a DFS response. EIRP is based on the highest antenna gain. For MIMO devices refer to KDB Publication 662911 D01. Sony Global Manufacturing & Operations Corporation EMC/RF Test Laboratory, Main Lab.

Project No: JB-Z0544-A Page 6 of 11 4. As Channel Move Time and Channel Closing Transmission Time testing, EUT transmissions are observed on spectrum analyzer from the end of radar burst until after 10 seconds. As Non-Occupancy Period testing, EUT transmissions are observed on spectrum analyzer more than 30 minutes after the Channel Move. Spectrum Analyzer Settings; Parameter Value RBW 3 MHz VBW 10 MHz Span Zero Span Detector Positive Peak Trace Clear / Write (Single Sweep) Sweep Point 30001 DFS Response Requirement Values; Parameter Value Remark Non-Occupancy Period Minimum 30 [min] - Channel Move Time 10 [sec] See Note 1 Channel Closing 200 [msec] + an aggregate of 60 [msec] over remaining See Note 1, 2 Transmission Time 10 [sec] period Note 1 : Channel Move Time and the Channel Closing Transmission Time should be performed with Radar Type 0. The measurement timing begins at the end of the Radar Type 0 burst. Note 2 : The Channel Closing Transmission Time is comprised of 200 msec starting at the beginning of the Channel Move Time plus any additional intermittent control signals required to facilitate a Channel move (an aggregate of 60 msec) during the remainder of the 10 second period. The aggregate duration of control signals will not count quiet periods in between transmissions. 1.5.
