2 1 i)\ c a 1 T able 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 millwatt —64 dBm EIRP < 200 millrwatt and —62 dBm power spectral density = 10 dBm/MHz EIRP < 200 millhrwatt that do not meet the power spectral —64 dBm density requirement Note 1: This is the level at the imput 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 transmussion waveforms to account for vanations 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 DQl. Table 4: 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 remaming 10 second period. See NMotes 1 and 2. LU—NII Detection Bandwidth Minmum 100% of the U— N 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 to facilitate a Channel move (an aggregate of 60 milliseconds) during the remaimmder of the 10 second period. The aggregate duration of control signals will not count quiet periods in between transmissions. Note 3: During the UL—NZ 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.

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG160608001-DFS TEST RESULTS Description of EUT The EUT operates in 5250-5350 MHz and 5470-5725 MHz range. The rated output power of master device is >23 dBm (EIRP), Therefore the required interference threshold level is -64 dBm, the required radiated threshold at antenna port is -64dBm. The calibrated radiated DFS detection threshold level is set to -64 dBm. WLAN traffic is generated by streaming the video file TestFile.mpg, this file is used by IP and Frame based systems for loading the test channel during the In-service compliance testing of the U-NII device. The file is streamed from the Access Point to the Client in full motion video mode using the media player with the V2.61 Codec package.

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG160608001-DFS CHANNEL MOVE TIME AND CHANNEL CLOSING TRANSMISSION TIME Test Procedure 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. repeat using a long pulse radar type5 waveform. 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. The aggregate channel closing transmission time is calculated as follows: Aggregate Transmission Time = N*Dwell Time N is the number of spectrum analyzer bins showing a device transmission Dwell Time is the dwell time per bin (i.e. Dwell Time = S/B, S is the sweep time and B is the number of bin, i.e. 8192) Test Results Frequency Bandwidth Radar Type Results (MHz) (MHz) 5290 80 Type 0 Compliant 5530 80 Type 0 Compliant Please refer to the following tables and plots.
