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 1 and 2 for the applicability of DFS requirements for each of the operational modes.

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 and 2) ≥ 200 milliwatt -64 dBm < 200 milliwatt -62 dBm 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. 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 Minimum 80% of the UNII 99% 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. Report No.: RF111011C17N-2 10 of 23 Report Format Version 5.0.0 Reference No.: 130724C01

PARAMETERS OF DFS TEST SIGNALS Step intervals of 0.1 microsecond for Pulse Width, 1 microsecond for PRI, 1 MHz for chirp width and 1 for the number of pulses will be utilized for the random determination of specific test waveforms.

5. TEST PROCEDURE 5.1 BV ADT DFS MEASUREMENT SYSTEM A complete BV ADT 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 6, 7 and 8. The traffic monitoring subsystem is specified to the type of unit under test (UUT). Radiated setup configuration of BV ADT DFS Measurement System The test transmission will always be from the Master Device to the Client Device. While the Client device is set up to associate with the Master device and play the MPEG file (6  Magic Hours) from Master device, the designated MPEG test file and instructions are located at: http://ntiacsd.ntia.doc.gov/dfs/.

5.2 CALIBRATION OF DFS DETECTION THRESHOLD LEVEL: The measured channel is 5500MHz and 5510MHz. The radar signal was the same as transmitted channels, and injected into the AP (master) or Client Device with Radar Detection, measured the channel closing transmission time and channel move time. The calibrated conducted detection threshold level is set to -64dBm. The tested level is lower than required level hence it provides margin to the limit.
