Note 2: 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. Note 3: E.I.R.P. is based on the highest antenna gain. For MIMO devices refer to KDB Publication 662911 D01. Table 4: DFS Response Requirement Values Parameter Value Non-occupancy period Minimum 30 minutes Channel Availability Check Time 60 seconds Channel Move Time 10 seconds See Note 1 Channel Closing Transmission Time 200 milliseconds + an aggregate of 60 milliseconds over remaining 10 second period. See Notes 1 and 2 U-NII Detection Bandwidth Minimum 100 % of the U-NII 99 % transmission power bandwidth See Note 3 Note 1: The 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 milliseconds 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 milliseconds) during the remainder of the 10 second period. The aggregate duration of control signal will not count quiet periods in between transmissions. Note 3: During the U-NII Detection Bandwidth detection test, radar type 0 should be used. For each frequency step the minimum percentage of detection is 90 percent. Measurements are performed with no data traffic. UL Japan, Inc.

The EUT uses one transmitter connected to a 50 ohm coaxial antenna ports. The antenna port is connected to the test system. WLAN traffic is generated by streaming the ping data with iperf.exe (ver.1.7.0) from the Master to the Client. (Channel loading was over 17 %) The EUT utilizes the 802.11a, 802.11n and 802.11ac architecture, with a nominal channel bandwidth. The EUT had used IEEE 802.11ac VHT80 (widest mode). The FCC ID for the Master Device used with EUT for DFS testing is LDK102073. The rated output power of the Master unit is > 200 mW (23 dBm). Therefore the required interference threshold level is -64 dBm. After correction for antenna gain and procedural adjustments, the required conducted threshold at the antenna port is - 64 + 1 + 4= -59 dBm (threshold level + additional 1 dB + antenna gain *1)). *1) Minimum antenna gain of Master Device (FCC ID: LDK102087, IC No.: 2461B-102087) UL Japan, Inc.

Test report No. : 12656071S-X-R1 Page : 14 of 22 Issued date : September 27, 2019 FCC ID : BKEHDH002 5.3 Test and Measurement System SYSTEM OVERVIEW The measurement system is based on a conducted test method. The software selects waveform parameters from within the bounds of the signal type on a random basis using uniform distribution. The short pulse types 2, 3, and 4, the long pulse type 5, and the frequency hopping type 6 parameters are randomized at run-time. The signal monitoring equipment consists of a spectrum analyzer with the capacity to display 8001 bins on the horizontal axis. A time-domain resolution of 2 ms/bin is achievable with a 16 seconds sweep time, meeting the 10 seconds short pulse reporting criteria. The aggregate ON time is calculated by multiplying the number of bins above a threshold during a particular observation period by the dwell time per bin, with the analyzer set to peak detection. A time-domain resolution of 3 ms/bin is achievable with a 24 seconds sweep time, meeting the 22 seconds long pulse reporting criteria and allowing a minimum of 10 seconds after the end of the long pulse waveform. FREQUENCY HOPPING RADAR WAVEFORM GENERATING SUBSYSTEM The first 100 frequencies are selected out of the hopping sequence of the randomized 475 hop frequencies. Only a Burst that has the frequency falling within the receiver bandwidth of the tested U-NII device is selected among those frequencies. (Frequency-domain simulation). The radar waveform generated at the start time of the selected Burst (Time-domain simulation) is download to the Signal Generator. If all of the randomly selected 100 frequencies do not fall within the receiver bandwidth of the U-NII device, the radar waveform is not used for the test.

Test report No. : 12656071S-X-R1 Page : 15 of 22 Issued date : September 27, 2019 FCC ID : BKEHDH002 SYSTEM CALIBRATION Step 1: Set the system as shown in Figure 4 of KDB 905462 D02 7.2.3. Step 2: Adjust each attenuator to fulfill the following three conditions: - WLAN can be communicated, and - Rader detection threshold level is bigger than Client Device traffic level on the spectrum analyzer, and - Master Device traffic level is not displayed on the spectrum analyzer. Step 3: Terminate 50 ohm at B, C, D and E points, and connect the spectrum analyzer to the point A. (See the figure on Section 5.3) At the point A, adjust the signal generator and spectrum analyzer to the center frequency of the channel to be measured. Download the applicable radar waveforms to the signal generator. Select the radar waveform, trigger a burst manually and measure the amplitude on the spectrum analyzer. Readjust the amplitude of the signal generator as required so that the peak level of the waveform is at a displayed level equal to the required or desired interference detection threshold. Separate signal generator amplitude settings are determined as required for each radar type. Step 4: Without changing any of the instrument settings, restore the system setting to Step 2 and adjust the Reference Level Offset of the spectrum analyzer to the level at Step 3. By taking the above steps 1 to 4, the spectrum analyzer displays the level of the signal generator as received at the antenna ports of the Master Device. See Clause 5.4 for Plots of Noise, Rader Waveforms, and WLAN signals. 5.4 Plots of Noise, Rader Waveforms, and WLAN signals Plots of System Noise Floor It was confirmed that the EUT did not transmit before having received appropriate control signals from a Master Device.

Test report No. : 12656071S-X-R1 Page : 17 of 22 Issued date : September 27, 2019 FCC ID : BKEHDH002 SECTION 6: In-Service Monitoring for Channel Move Time, Channel Closing Transmission Time 6.1 Operating environment Test place : No.3 Shielded room Temperature : 25 deg.C Humidity : 48 %RH 6.2 Test Procedure Transfer files from the Master Device to the Client Device on the tested channel during the entire period of the test. The Radar Waveform generator sends a Burst of pulses for one of the Short Pulse Radar Types 0 at levels defined , on the Operating Channel. An additional 1 dB is added to the radar test signal to ensure it is at or above the DFS Detection Threshold, accounting for equipment variations/errors. Observe the transmissions of the EUT at the end of the radar Burst on the Operating Channel for duration greater than 10 seconds. 6.3 Test data Test Item Unit Measurement Time Limit Results Channel Move Time *1) [s] 0.060 10.000 Pass Channel Closing Transmission Time *2) [ms] 0 60 Pass *1) Channel Move Time is calculated as follows: (Channel Move Time) = (End of Transmission) - (End of Burst) *2) Channel Closing Transmission Time is calculated from (End of Burst + 200 ms) to (End of Burst + 10 s) (Channel Closing Transmission Time) = (Number of analyzer bins showing transmission) x (dwell time per bin) = 0 x 2 [ms] UL Japan, Inc.

Transfer files from the Master Device to the Client Device on the tested channel during the entire period of the test. The Radar Waveform generator sends a Burst of pulses for one of the Radar Types 0 at levels defined on the Operating Channel. An additional 1 dB is added to the radar test signal to ensure it is at or above the DFS Detection Threshold, accounting for equipment variations/errors. Observe the transmissions of the EUT after the Channel Move Time on the Operating Channel for duration greater than 30 minutes. 2). Transfer files from the Master Device to the Client Device on the tested channel during the entire period of the test. Observe the transmissions of the EUT on the Operating Channel for duration greater than 30 minutes after the Master Device is shut off. 7.3 Test data 1).Radar Type 0 Marker 1 : End of Burst : 22.32 s Marker 2 : End of Burst + 10 s : 32.32 s * Measurement non-occupancy period: 31.46 minutes or more (1920 [s] – 32.32 [s] = 1887.68 [s] = 31.46 [minutes]) UL Japan, Inc.
