Page 9 of 25 Report No.: STS1906274W17 2.3 DFS MEASUREMENT INSTRUMENTATION a. RADAR GENERATION SYSTEM An Agilent PSG is used as the radar-generating source. The integral arbitrary waveform generators are programmed using Agilent’s “Pulse Building” software and Elliott custom software to produce the required waveforms, with the capability to produce both unmodulated and modulated (FM Chirp) pulses. Where there are multiple values for a specific radar parameter then the software selects a value at random and, for FCC tests,the software verifies that the resulting waveform is truly unique. With the exception of the hopping waveforms required by the FCC’s rules (see below),the radar generator is set to a single frequency within the radar detection bandwidth of the EUT. Frequency hopping radar waveforms are simulated using a time domain model. A randomly hopping sequence algorithm (which uses each channel in the hopping radar’s range once in a hopping sequence) generates a hop sequence. A segment of the first 100 elements of the hop sequence are then examined to determine if it contains one or more frequencies within the radar detection bandwidth of the EUT. If it does not then the first element of the segment is discarded and the next frequency in the sequence is added. The process repeats until a valid segment is produced. The radar system is then programmed to produce bursts at time slots coincident with the frequencies within the segment that fall in the detection bandwidth. The frequency of the generator is stepped in 1 MHz increments across the EUT’s detection range. The radar signal level is verified during testing using a CW signal with the AGC function switched on. Correction factors to account for the fact that pulses are generated with the AGC functions switched off are measured annually and an offset is used to account for this in the software.The generator output is connected to the coupling port of the conducted set-up or to the radar-generating antenna. b. CHANNEL MONITORING SYSTEM Channel monitoring is achieved using a spectrum analyzer and digital storage oscilloscope. The analyzer is configured in a zero-span mode, center frequency set to the radar waveform’s frequency or the center frequency of the EUT’s operating channel. The IF output of the analyzer is connected to one input of the oscilloscope and analyzer. A signal generator output is set to send either the modulating signal directly or a pulse gate with an output pulse co-incident with each radar pulse. This output is connected to a second input on the oscilloscope and the oscilloscope displays both the channel traffic (via the if input) and the radar pulses on its display. For in service monitoring tests the analyzer sweep time is set to > 20 seconds and the oscilloscope is configured with a data record length of 10 seconds for the short duration and frequency hopping waveforms, 20 seconds for the long duration waveforms. Both instruments are set for a single acquisition sequence. The analyzer is triggered 500ms before the start of the waveform and the oscilloscope is triggered directly by the modulating pulse train. Timing measurements for aggregate channel transmission time and channel move time are made from the oscilloscope data, with the end of the waveform clearly identified by the pulse train on one trace. The analyzer trace data is used to confirm that the last transmission occurred within the 10-second record of the

Page 10 of 25 Report No.: STS1906274W17 oscilloscope. If necessary the record length of the oscilloscope is expanded to capture the last transmission on the channel prior to the channel move. Channel availability check time timing plots are made using the analyzer. The analyzer is triggered at start of the EUT’s channel availability check and used to verify that the EUT does not transmit when radar is applied during the check time. The analyzer detector and oscilloscope sampling mode is set to peak detect for all plots. 2.4 EQUIPMENTS LIST FOR ALL TEST ITEMS Kind of Last Calibrated Manufacturer Type No. Serial No. Equipment calibration until Signal Agilent N5182A MY46240556 2018.10.16 2019.10.15 Generator Signal Agilent N9020A MY49100060 2018.10.13 2019.10.12 Analyzer Coupler Rio tinto in overseas ZFSC-2-11 15542 2019.05.06 2020.05.05 Coupler Rio tinto in overseas ZN2PD-9G SF078500430 2019.05.06 2020.05.05 Attenuator HP 8494B DC-18G 2019.05.06 2020.05.05 Router LINKSY(ID:Q87-WRT3200ACM) WRT3200ACM 1.98116E+13 N.C.R N.C.R Temperature & HH660 Mieo N/A 2018.10.11 2019.10.10 Humidity

DFS – CHANNEL CLOSING TRANSMISSION TIME AND CHANNEL MOVE TIME 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. 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 signals will not count quiet periods in between transmissions. b. DFS – CHANNEL NON-OCCUPANCY AND VERIFICATION OF PASSIVE SCANNING Non-occupancy Period. A channel that has been flagged as containing a radar system, either by a channel availability check or in-service monitoring, is subject to a non-occupancy period of at least 30 minutes. The non-occupancy period starts at the time when the radar system is detected. c. CHANNEL AVAILABILITY CHECK TIME Channel Availability Check Time. A U-NII device shall check if there is a radar system already operating on the channel before it can initiate a transmission on a channel and when it has to move to a new channel. The U-NII device may start using the channel if no radar signal with a power level greater than the interference threshold values listed in paragraph (h)(2) of this section, is detected within 60 seconds. d. CONTROL (TPC) Compliance with the transmit power control requirements for devices is demonstrated through measurements showing multiple power levels and manufacturer statements explaining how the power control is implemented. e. DETECTION PROBABILITY / SUCCESS RATE 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. Minimum 100% of the U-NII 99% transmission power bandwidth. f. NON- OCCUPANCY PERIOD During the 30 minutes observation time, UUT did not make any transmissions on a channel after a radar signal was detected on that channel by either the Channel Availability Check or the In-Service Monitoring

Page 16 of 25 Report No.: STS1906274W17 3.2.3 DFS CONDUCTION TEST METHOD a. The signal level of the simulated waveform is set to a reference level equal to the threshold level (plus 1dB if testing against FCC requirements). Lower levels may also be applied on request of the manufacturer. The signal level is verified by measuring the CW signal level at the coupling point to the RDD antenna port. The radar signal level is calculated from the measured level, R (dBm) and the lowest gain antenna assembly intended for use with the RDD If both master and client devices have radar detection capability then the radar level at the non RDD is verified to be at least 20dB below the threshold level to ensure that any responses are due to the RDD detecting radar. The antenna connected to the channel monitoring subsystem is positioned to allow both master and client transmissions to be observed, with the level of the EUT’s transmissions between 6 and 10dB higher than those from the other device. b. Set-upB is a set-up whereby the UUT is an RLAN device operating in slave mode, with or without Radar Interference Detection function. This set-up also contains an RLAN device operating in master mode. The radar test signals are injected into the master device. The UUT (slave device)is associated with the master device. Figure 5 shows an example for Set-up B. The set-up used shall be documented in the test report.
