Report Number: 1811FR22 Table 3: DFS Detection Thresholds for Master Devices and Client Devices With Radar Detection Maximum Transmit Power Value (See Notes 1,2 and 3) EIRP ≥ 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 spectral -64 dBm 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. Note 3: EIRP is based on the highest antenna gain. For MIMO devices refer to FCC KDB Publication 662911 D01.

See Notes 1 and 2. Minimum 100 % of the U-NII 99 % transmission power U-NII Detection Bandwidth 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 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 0 should be used. For each frequency step the minimum percentage of detection is 90 percent. Measurements are performed with no data traffic. 9 of 23

System Calibration The short pulse types 0,1,2, 3 and 4, and the long pulse type 5 parameters are randomized at run—time The hopping type 6 pulse parameters are fixed while the hopping sequence is based on the May 2014 NTIA Hopping Frequency List. The intial 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 sofware creates a hopping burst pattem in accordance with Section 7.4.1.3 Method #2 Simulated Frequency Hopping Radar Waveform Generating Subsystem of FCC KDB 905462 D02 UNII DFS Compliance Procedures New Rules vO2 The frequency of the signal generator is incremented in 1 MFz steps from FL to FH for each successive trial. This incremental sequence is repeated as required to generate a minmum of 30 total trials and to maintain a uniform frequency distribution over the entire Detection Bandwicth The signal monitoring equipment consists of a spectrum analyzer. 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 12 of 23

Report Number: 1811FR22 3.2.3. System Calibration The Interference Radar Detection Threshold Level is (-64 dBm), The above equipment setup was used to calibrate the radiated Radar Waveform. A vector signal generator was utilized to establish the test signal level for each radar type. During this process there were replace 50 ohm terminal form Master and Client device and no transmissions by either the Master or Client Device. The spectrum analyzer was switched to the zero span (Time Domain) at the frequency of the Radar Waveform generator. Peak detection was used.The spectrum analyzer resolution bandwidth (RBW) and video bandwidth (VBW) were set to at least 3 MHz. The vector signal generator amplitude was set so that the power level measured at the spectrum analyzer was (-64 dBm). Capture the spectrum analyzer plots on short pulse radar types, long pulse radar type and hopping radar waveform. 3.2.4. Adjustment of Displayed Traffic Level A link is established between the Master and Slave and the distance between the units is adjusted as needed to provide a suitable received level at the Master and Slave devices. Software to ping the client is permitted to simulate data transfer but must have random ping intervals. The monitoring antenna is adjusted so that the WLAN traffic level, as displayed on the spectrum analyzer, is at lower amplitude than the radar detection threshold. 3.3.

The delta marker is set at the end of the last WLAN transmission following the radar pulse. This delta is the channel move time. The aggregate channel closing transmission time is calculated as follows: Aggregate Transmission Time = (Number of analyzer bins showing transmission) * (dwell time per bin) 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.
