Measurements, Examination And Derived Results 6.1 Dynamic Frequency Selection (DFS) 6.1.1General introduction Interference Threshold values, Master or Client incorporating In-Service Monitoring Maximum Transmit Power Value (see note) ≥ 200 milliwatt -64 dBm EIRP < 200 milliwatt and -62 dBm power spectral density < 10 dBm/MHz EIRP < 200 milliwatt that do not meet the power -64 dBm spectra density requirement Note 1: This is the level at the input of the receiver assuming a 0 dBi receive antenna. 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. Note3: EIRP is based on the highest antenna gain. For MIMO devices refer to KDB Publication 662911 D01. 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 UNII 99% transmission power bandwidth See Note 3. 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 milliseconds starting at the beginning of the Channel Move Time plus any additional intermittent control signals required facilitating a Channel move (an aggregate of 60 milliseconds) during the remainder of the 10 second period. The aggregate duration of control signals 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.

Test Report No. 18070418-FCC-R Page 12 of 26 Radar Test Waveforms This section provides the parameters for required test waveforms, minimum percentage of successful detections, and the minimum number of trials that must be used for determining DFS conformance. Step intervals of 0.1 microsecond for Pulse Width, 1 microsecond for PRI, 1 MHz for chirp width and 1 for the number of pulses will be utilized for the random determination of specific test waveforms 1. Short Pulse Radar Test Waveforms Minimum Pulse Radar Percentage of Width PRI (μsec) Number of Pulses Minimum Type Successful (μsec) Detection 0 1 1428 18 See Note 1 See Note 1 Test A: 15 unique PRI Roundup { (1/360) * values randomly (19 selected from the list of 106/PRI𝑢𝑠𝑒𝑐 23 PRI values in Table 5a 1 1 60% 30 60% 30 Test B: 15 unique PRI values randomly selected within the range of 518-3066 - μsec, with a minimum increment of 1 μsec, excluding PRI values selected in Test A 2 1-5 150-230 23-29 60% 30 3 6-10 200-500 16-18 60% 30 4 11-20 200-500 12-16 60% 30 Aggregate (Radar Types 1-4) 80% 120 Note 1: Short Pulse Radar Type 0 should be used for the detection bandwidth test, channel move time, and channel closing time tests. 2. Long Pulse Radar Test Waveform Radar Pulse Chirp PRI Number Number Minimum Minimum Type Width Width (μsec) of Pulses of Bursts Percentage Trials (μsec) (MHz) per Burst of Successful Detection 5 50-100 5-20 1000-2000 1-3 8-20 80% 30 The parameters for this waveform are randomly chosen. Thirty unique waveforms are required for the Long Pulse radar test signal. If more than 30 waveforms are used for the Long Pulse radar test signal, then each additional waveform must also be unique and not repeated from the previous waveforms. Each waveform is defined as follows: 1) The transmission period for the Long Pulse Radar test signal is 12 seconds.

Test Report No. 18070418-FCC-R Page 13 of 26 2) There are a total of 8 to 20 Bursts in the 12 second period, with the number of Bursts being randomly chosen. This number is Burst_Count. 3) Each Burst consists of 1 to 3 pulses, with the number of pulses being randomly chosen. Each Burst within the 12 second sequence may have a different number of pulses. 4) The pulse width is between 50 and 100 microseconds, with the pulse width being randomly chosen. Each pulse within a Burst will have the same pulse width. Pulses in different Bursts may have different pulse widths. 5) Each pulse has a linear FM chirp between 5 and 20 MHz, with the chirp width being randomly chosen. Each pulse within a Burst will have the same chirp width. Pulses in different Bursts may have different chirp widths. The chirp is centered on the pulse. For example, with a radar frequency of 5300 MHz and a 20 MHz chirped signal, the chirp starts at 5290 MHz and ends at 5310 MHz. 6) If more than one pulse is present in a Burst, the time between the pulses will be between 1000 and 2000 microseconds, with the time being randomly chosen. If three pulses are present in a Burst, the time between the first and second pulses is chosen independently of the time between the second and third pulses. 7) The 12 second transmission period is divided into even intervals. The number of intervals is equal to Burst_Count. Each interval is of length (12,000,000 / Burst_Count) microseconds. Each interval contains one Burst. The start time for the Burst, relative to the beginning of the interval, is between 1 and [(12,000,000 / Burst_Count) – (Total Burst Length) + (One Random PRI Interval)] microseconds, with the start time being randomly chosen. The step interval for the start time is 1 microsecond. The s9tart time for each Burst is chosen independently. A representative example of a Long Pulse radar test waveform: 1) The total test signal length is 12 seconds. 2) 8 Bursts are randomly generated for the Burst Count. 3) Burst 1 has 2 randomly generated pulses. 4) The pulse width (for both pulses) is randomly selected to be 75 microseconds. 5) The PRI is randomly selected to be at 1213 microseconds. 6) Bursts 2 through 8 are generated using steps 3 – 5. 7) Each Burst is contained in even intervals of 1,500,000 microseconds. The starting location for Pulse 1, Burst 1 is randomly generated (1 to 1,500,000 minus the total Burst 1 length + 1 random PRI interval) at the 325,001 microsecond step. Bursts 2 through 8 randomly fall in successive 1,500,000 microsecond intervals (i.e. Burst 2 falls in the 1,500,001 – 3,000,000 microsecond range) 3. Frequency Hopping Radar Type Minimum Hopping Pulse Percentage Radar Pulses Hopping Sequence Minimum Width PRI (μsec) of Type per Hop Rate (kHz) Length Trials (μsec) Successful (msec) Detection 6 1 333 9 0.333 300 70% 30

Test Report No. 18070418-FCC-R Page 14 of 26 For the Frequency Hopping Radar Type, the same Burst parameters are used for each waveform. The hopping sequence is different for each waveform and a 100-length segment is selected 1 from the hopping sequence defined by the following algorithm: The first frequency in a hopping sequence is selected randomly from the group of 475 integer frequencies from 5250 – 5724 MHz. Next, the frequency that was just chosen is removed from the group and a frequency is randomly selected from the remaining 474 frequencies in the group. This process continues until all 475 frequencies are chosen for the set. For selection of a random frequency, the frequencies remaining within the group are always treated as equally likely. 6.1.2 Radar Waveform Calibration The following equipment setup was used to calibrate the conducted Radar Waveform. A spectrum analyzer was used to establish the test signal level for each radar type. During this process there were no transmissions by either the Master or Client Device. The spectrum analyzer was switched to the zero span (Time Domain) mode at the frequency of the Radar Waveform generator. Peak detection was utilized. The spectrum analyzer resolution bandwidth (RBW) and video bandwidth (VBW) were set to 3 MHz. For a detection threshold level of -62dBm and the Master antenna gain is -0.98 dBi for the band 5250-5350MHz, and - 0.26 dBi for the band 5470-5725MHz., required detection threshold is -62.98dBi for the band 5250-5350MHz, and - 62.26 dBi for the band 5470-5725MHz. Note: Maximum Transmit Power is less than200 milliwatt in this report, so detection threshld level is -62dBm

Test Report No. 18070418-FCC-R Page 15 of 26 The device transmits one type of radar as specified in the DFS Order. The Required detection threshold is -61.30dBm = -62 +0.7dBi. The conducted radar burst level is set to - 61.30dBm. 5310-Radar signal 5510-Radar signal

Test Report No. 18070418-FCC-R Page 16 of 26 6.1 In-Service Monitoring for Channel Move Time , Channel Closing Transmission Time and Non- Occupancy Period These tests define how the following DFS parameters are verified during In-Service Monitoring; Channel Closing Transmission Time, Channel Move Time, and Non-Occupancy Period. The steps below define the procedure to determine the above mentioned parameters when a radar Burst with a level equal to the DFS Detection Threshold + 1dB is generated on the Operating Channel of the U-NII device. the UUT (Client) operating as a Client Device will associate with master at Mid Channel. Stream the MPEG test file from the Master Device to the Client Device on the selected Channel for the entire period of the test. At time T0 the Radar Waveform generator sends a Burst of pulses for each of the radar types at -62dBm. Observe the transmissions of the UUT at the end of the radar Burst on the Operating Channel for duration greater than 10 seconds. Measure and record the transmissions from the UUT during the observation time (Channel Move Time). Compare the Channel Move Time and Channel Closing Transmission Time results to the limits defined in the DFS Response requirement values table. Channel Closing Transmission Time- Measurement A type 1 waveform was introduced to the EUT and the Spectrum Analyzer sweep time was set to 1s for monitoring and capturing the plot. A LabView program was created to collect trace data and capturing the plot. The program will calculate the channel closing time base on the spectrum analyzer result. The result will be calculated based on FCC procedure. C= N*Dwell

Test Report No. 18070418-FCC-R Page 17 of 26 C is the closing time, N is the number of spectrum analyzer sampling bins showing a U-NII transmission and dwell is the dwell time per bin. Dwell= S/B Where Dwell is the dwell time per spectrum analyzer sampling bin, S is the sweep time and B is the number 0f spectrum analyzer sampling bins. 10.1.4 DFS Test Setup Test Setup Block Diagram The radio was set at the center channel frequency of tested Channel. A FCC approved mater device – (FCC ID: Q87-WBV-AP230) AP was used to link with the UUT (Client) device. For the frequency bands 5250MHz to 5725MHz the master device provides, on aggregate, uniform loading of the spectrum across all devices by selecting an operating channel among the available channels using a random algorithm.
