Test report no.: 1-2904/16-01-02-B 9 RF measurements 9.1 Description of test setup 9.1.1 Conducted measurements Setup Figure 1 shows a setup whereby the UUT is a RLAN device operating in slave mode, without Radar Interference Detection function. This setup also contains a 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 1 shows an example Figure 1: Setup RPP = SG - CA (RPP-radar pulse power; SG-signal generator power; CA-loss signal path) Example calculation: RPP [dBm] = -30.0 [dBm] – 33.0 [dB] = -63.0 [dBm] Page 9 of 21

Test report no.: 1-2904/16-01-02-B 9.2 Parameters of DFS test signals 9.2.1 DFS Detection Thresholds for Master Devices as well as Client Devices With Radar Detection Value Maximum Transmit Power EIRP (see note) ≥ 200 mW -64 dBm < 200 mW and -62 dBm power spectral density < 10 dBm/MHz < 200 mW and -64 dBm that do not meet the power spectral density < 10 dBm/MHz 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. 9.2.2 DFS Response Requirement Values Parameter Value Non-occupancy period minimum 30 minutes Channel Availability Check Time 60 seconds 10 seconds Channel Move Time See Note 1. 200 milliseconds + an aggregate of 60 milliseconds Channel Closing Transmission Time over remaining 10 second period. See Notes 1 and 2. Minimum 100% of the U-NII 99% transmission U-NII Detection Bandwidth 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 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. Page 11 of 21

The hopping sequence is different for each waveform and a 100-length segment is selected from the hopping sequence defined. 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. Page 14 of 21

Test report no.: 1-2904/16-01-02-B 9.3 Test preparation 9.3.1 Channel loading Timing plots are required with calculations demonstrating a minimum channel loading of approximately 17% or greater. For example, channel loading can be estimated by setting the spectrum analyzer for zero span and approximate the Time On/ (Time On + Off Time). This can be done with any appropriate channel BW and modulation type.

Transmissions during this period shall consist of normal traffic for a maximum of 200 ms after detection of the radar signal.
