DFS (Dynamic Frequency Selection) test description 3.1. Applicability The following table from KDB 905462 D02 v02 lists the applicable requirements for the DFS testing. The device evaluated in this report is considered a client device without radar detection capability. Requirement Operational Mode Client Without Radar Client With Radar Master Detection Detection Non-Occupancy Period Yes Not required Yes DFS Detection Threshold Yes Not required Yes Channel Availability Check Time Yes Not required Not required U-NII Detection Bandwidth Yes Not required Yes Table 2.1. DFS Applicability Requirement Operational Mode Master Device or Client Client Without with Radar Detection Radar Detection DFS Detection Threshold Yes Not required Channel Closing Transmission Time Yes Yes Channel Move Time Yes Yes U-NII Detection Bandwidth Yes Not required Non-Occupancy Period NA/Yes Yes Additional requirements for Master Device or Client with Client Without Radar Detection devices with multiple Radar Detection U-NII Detection Bandwidth and All BW modes must be tested Not required statistical Performance Check Channel Move Time and Channel Test using widest BW mode Test using the widest BW mode Closing Transmission Time available available for the link All other tests Any single BW mode Not required Note: Frequencies selected for statistical performance check (Section 7.8.4) should include several frequencies within the radar detection bandwidth and frequencies near the edge of the radar detection bandwidth. For 802.11 devices it is suggested to select frequencies in each of the bonded 20 MHz channels and the channel center frequency. Table 2.2.

Requirements KDB 905462 D02 v02 the following are the requirements for Client Devices: a) A Client Device will not transmit before having received appropriate control signals from a Master Device. b) A Client Device will stop all its transmissions whenever instructed by a Master Device to which it is associated and will meet the Channel Move Time and Channel Closing Transmission Time requirements. The Client Device will not resume any transmissions until it has again received control signals from a Master Device. c) If a Client Device is performing In-Service Monitoring and detects a Radar Waveform above the DFS Detection Threshold, it will inform the Master Device. This is equivalent to the Master Device detecting the Radar Waveform and d) through f) of section 5.1.1 apply. d) Irrespective of Client Device or Master Device detection the Channel Move Time and Channel Closing Transmission Time requirements remain the same. e) The client test frequency must be monitored to ensure no transmission of any type has occurred for 30 minutes. Note: If the client moves with the master, the device is considered compliant if nothing appears in the client non-occupancy period test. For devices that shutdown (rather than moving channels), no beacons should appear 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 Minimum 100% of the U-NII 99% transmission power bandwidth. See Note3. 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 (and 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 the used. For each frequency step the minimum percentage of detection is 90 percent. Measurements are performed with no data traffic. Table 2.3.

DFS Detection Thresholds The DFS detection thresholds are defined for Master devices and Client Devices with In-service monitoring. These detection Thresholds are listed in the following table. Value Maximum Transmit Power (See Notes 1, 2, and 3) EIRP ≥ 200 milliwatt -64 ㏈m EIRP< 200 milliwatt and -62 ㏈m Power spectral density < 10 ㏈m/㎒ EIRP < 200 milliwatt that do not meet the power spectral -64 ㏈m 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 respons. Note 3: EIRP is based on the highest antenna gain. For MIMO devices refer to KDB Publication 662911 D01 Table 2.4.

An upper bound of the aggregate duration of the channel closing transmission time is calculated by: C = N × Dwell; Where C is the closing time, N is the number of spectrum analyzer sampling bins showing a U-NII transmission and dwell is the dwell time per bin. Dwell = [S] / [B] = 10 / 32001 = 0.000312 Closing Transmission Time[C] = [N] × [Dwell] = 1 × 0.000312 = 0.000312 s = 0.312 ms This report shall not be reproduced except in full, without the written approval of KES Co., Ltd.
