3. U-NII DFS Rule Requirements 3.1 Working Modes and Required Test Items The manufacturer shall state whether the UUT is capable of operating as a Master and/or a Client. If the UUT is capable of operating in more than one operating mode then each operating mode shall be tested separately. See tables 6 and 7 for the applicability of DFS requirements for each of the operational modes. Table 6: Applicability of DFS Requirements Prior To Use a Channel Operational Mode Requirement Client without radar Client with radar Master detection detection Non-Occupancy Period   note  DFS Detection Threshold  Not required  Channel Availability Check Time  Not required Not required U-NII Detection Bandwidth  Not required  Note: Regarding KDB 905462 D03 Client Without Radar Detection New Rules v01r02 section(b)(5/6), 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 shut down (rather than moving channels), no beacons should appear. An analyzer plot that contains a single 30-minute sweep on the original channel.

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 Value Maximum Transmit Power (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 -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. Note3: EIRP is based on the highest antenna gain. For MIMO devices refer to KDB Publication 662911 D01. Table 9: 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 Channel Closing Transmission Time milliseconds 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.
