2.6 Transmit Power Control (TPC) U-NII devices operating in the 5.25-5.35 GHz band and the 5.47-5.725 GHz band shall employ a TPC mechanism. 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 e.i.r.p. of less than 500 mW. Maximum EIRP of this device is 185.353 mW which less than 500mW, therefore it’s not require TPC function TPC E.I.R.P FCC 15.407(h)(1) > 500mW The TPC mechanism is required for system with an E.I.R.P. of above 500mW  < 500mW The TPC mechanism is not required for system with an E.I.R.P. of less 500mW 2.7 Statement of Maunfacturer 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. Report No.: RF180828C26-2 Page No. 8 / 26 Report Format Version: 6.1.2

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 DFS 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. Table 7: Applicability of DFS Requirements during Normal Operation. Operational Mode Requirement Master or Client with radar Client without radar detection detection DFS Detection Threshold  Not required Channel Closing Transmission Time   Channel Move Time   U-NII Detection Bandwidth  Not required Additional requirements for devices with Master or Client with radar Client without radar detection multiple bandwidth modes detection U-NII Detection Bandwidth and Statistical All BW modes must be tested Not required Performance Check Channel Move Time and Channel Closing Test using widest BW mode Test using the widest BW mode 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.

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 power U-NII Detection Bandwidth 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. Report No.: RF180828C26-2 Page No. 10 / 26 Report Format Version: 6.1.2

5. Test Procedure 5.1 DFS Measurement System A complete DFS Measurement System consists of two subsystems: (1) the Radar Signal Generating Subsystem and (2) the Traffic Monitoring Subsystem. The control PC is necessary for generating the Radar waveforms in Table 10, 11 and 12. The traffic monitoring subsystem is specified to the type of unit under test (UUT). Conducted setup configuration of DFS Measurement System System testing will be performed with channel-loading using means appropriate to the data types that are used by the unlicensed device. The following requirements apply: a) The data file must be of a type that is typical for the device (i.e., MPEG-2, MPEG-4, WAV, MP3, MP4, AVI, etc.) and must generally be transmitting in a streaming mode. b) Software to ping the client is permitted to simulate data transfer but must have random ping intervals. c) Timing plots are required with calculations demonstrating a minimum channel loading of approximately V 17% or greater. d) Unicast or Multicast protocols are preferable but other protocols may be used. The appropriate protocol used must be described in the test procedures. Report No.: RF180828C26-2 Page No. 14 / 26 Report Format Version: 6.1.2

Wireless Traffic Loading Traffic Signal Noise Floor 5.2 Calibration of DFS Detection Threshold Level The measured channel is 5500MHz, 5510MHz and 5530MHz. The radar signal was the same as transmitted channels, and injected into the antenna of AP (master) or Client Device with Radar Detection, measured the channel closing transmission time and channel move time. The calibrated detection threshold level is set to -64dBm. The tested level is lower than required level hence it provides margin to the limit.
