3.2 TEST LIMITS AND RADAR SIGNAL PARAMETERS DETECTION THRESHOLD VALUES Table 5: DFS Detection Thresholds for Master Devices and Client Devices With Radar Detection. Value Maximum Transmit Power (See Notes 1 and 2) EIRP≥ 200 milliwatt -64 Bm EIRP < 200 milliwatt and -62 dBm Power pectral density < 10 dBm/MHz EIRP < 200 milliwatt that do not meet the -64 dBm power spectral de sity 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. Report No.: BTL-FCCP-5-1711C150 Page 8 of 23

Table 6: 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. 200 milliseconds + an aggregate of 60 Channel Closing Transmission Time milliseconds over remaining 10 second period. See Notes 1 and 2. Minimum 80% of the UNII 99% transmission U-NII Detection Bandwidth power bandwidth. See Note 3. Note 1: The instant that the Channel Move Time and the Channel Closing Transmission Time begins is as follows: • For the Short Pulse Radar Test Signals this instant is the end of the Burst. • For the Frequency Hopping radar Test Signal, this instant is the end of the last radar Burst generated. • For the Long Pulse Radar Test Signal this instant is the end of the 12 second period defining the Radar Waveform. 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 signals will not count quiet periods in between transmissions. Note 3: During the U-NII Detection Bandwidth detection test, radar type 1 is used and for each frequency step the minimum percentage of detection is 90 percent. Measurements are performed with no data traffic. Report No.: BTL-FCCP-5-1711C150 Page 9 of 23

5. EMC EMISSION TEST 5.1 DFS MEASUREMENT SYSTEM: Test Precedure 1. Master device and client device are set up by conduction method as the following configuration. 2. The client device is connected to notebook and to access a IP address on wireless connection with the master device. 3. Then the master device is connected to another notebook to access a IP address. 4. Finally, let the two IP addresses run traffic with each other through the Run flow software “Lan test” to reach 17% channel loading as below Setup Report No.: BTL-FCCP-5-1711C150 Page 13 of 23

11ac 80MHz Mode The hopping type 6 pulse parameters are fixed while the hopping sequence is based on the August 2005 NTIA Hopping Frequency List. The initial starting point randomized at run-time and each subsequent starting point is incremented by 475. Each frequency in the 100-length segment is compared to the boundaries of the EUT Detection Bandwidth and the software creates a hopping burst pattern in accordance with Section 7.4.1.3 Method #2 Simulated Freqeuncy Hopping Radar Waveform Generating Subsystem of FCC 06-96. The frequency of the signal generator is incremented in 1 MHz steps from FL to FH for each successive trial. This incremental sequence is repeated as required to generate a minimum of 30 total trials and to maintain a uniform frequency distribution over the entire Detection Bandwidth. The signal monitoring equipment consists of a spectrum analyzer set to display 8001 bins on the horizontal axis. The time-domain resolution is 2 msec / bin with a 16 second sweep time, meeting the 10 second 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 and max hold. Should multiple RF ports be utilized for the Master and/or Slave devices (for example, for diversity or MIMO implementations), additional combiner/dividers are inserted between the Master Combiner/Divider and the pad connected to the Master Device (and/or between the Slave Combiner/Divider and the pad connected to the Slave Device). Additional pads are utilized such that there is one pad at each RF port on each EUT. Report No.: BTL-FCCP-5-1711C150 Page 15 of 23

5.2 CALIBRATION OF DFS DETECTION THRESHOLD LEVEL: A 50 ohm load is connected in place of the spectrum analyzer, and the spectrum analyzer is connected in place of the master device and the signal generator is set to CW mode. The amplitude of the signal generator is adjusted to yield a level of –62 dBm as measured on the spectrum analyzer. Without changing any of the instrument settings, the spectrum analyer is reconnected to the Common port of the Spectrum Analyzer Combiner/Divider. Measure the amplitude and calculate the difference from –62 dBm. Adjust the Reference Level Offset of the spectrum analyzer to this difference. The spectrum analyzer displays the level of the signal generator as received at the antenna ports of the Master Device. The interference detection threshold may be varied from the calibrated value of –62 dBm and the spectrum analyzer will still indicate the level as received by the Master Device. Set the signal generator to produce a radar waveform, trigger a burst manually and measure the level 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. 5.3 DEVIATION FROM TEST STANDARD No deviation. Report No.: BTL-FCCP-5-1711C150 Page 16 of 23

Master with injection at the Master. (Radar Test Waveforms are injected into the Master) 6.3 DFS DETECTION THRESHOLD Calibration: The EUT is slave equipment with a max gain is 0.5 dBi. For a detection threshold level of -62dBm and the master (Brand: GPON ONU, Model: G-240W-B, FCC ID: 2ADZRG240WB) antenna gain is 2.90 dBi, required detection threshold is -59.10 dBm (= -62+2.90). Note: Maximum Transmit Power is less than 200 milliwatt in this report, so detection threshold level is -62dBm. Report No.: BTL-FCCP-5-1711C150 Page 17 of 23
