The U-NII device is required to have the capability to operate at least 6 dB below the mean EIRP value of 30 dBm. A TPC mechanism is not required for systems with an EIRP of less than 500 mW. Maximum EIRP of this device is 20.845mW which less than 500mW, therefore it’s not require TPC function. 2.7 STATEMENT OF MAUNFACTURER This device (Client) is without radar detection, then the manufacturer statement confirming that information regarding the parameters of the detected Radar Waveforms is not available to the end user. And the device doesn’t have Ad Hoc mode on DFS frequency band. Bureau Veritas Shenzhen Co., Ltd.

Test Report No.: RF160524W004-7 3.2 TEST LIMITS AND RADAR SIGNAL PARAMETERS DETECTION THRESHOLD VALUES TABLE 8: DFS DETECTION THRESHOLDS FOR MASTER DEVICES AND CLIENT DEVICES WITH RADAR DETECTION MAXIMUM TRANSMIT POWER VALUE (SEE Note 1, 2 and 3) EIRP ≥ 200 milliwatt -64 dBm EIRP < 200 milliwatt and power spectral -62 dBm density < 10 dBm/MHz EIRP < 200 milliwatt that do not meet the -64 dBm power spectral 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 KDB Publication 662911 D01. Bureau Veritas Shenzhen Co., Ltd.

Test Report No.: RF160524W004-7 TABLE 9: 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 remaining 10 second period. See Notes 1 and 2. U-NII Detection Bandwidth 100% of the UNII transmission 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. Bureau Veritas Shenzhen Co., Ltd.
