        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.



2.2 Interference Threshold values, Master or Client incorporating
    In-Service Monitoring
                      Maximum Transmit Power                              Value (see notes 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.
       The radar Detection Threshold, lowest antenna gain is the parameter of Interference radar DFS
       detection threshold, The Interference Detection Threshold is the ( -62dBm) + (0) [dBi]+ 1 dB= -61 dBm.

        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 99% 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 transmission.
        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 Channel changes (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 is used and for each
        frequency step the minimum percentage of detection is 90%. Measurements are performed with no
        data traffic.

2.4 Short Pulse Radar Test Waveforms
       As the EUT is a Client Device with no Radar Detection, only one type radar pulse is required for the
       testing. Radar Pulse type 0 was used in the evaluation of the Client device for the purpose of
       measuring the Channel Move Time and the Channel Closing Transmission Time.

       increment of 1 μsec, excluding PRI values selected in Test A


       A minimum of 30 unique waveforms are required for each of the short pulse radar types 2 through 4.
       For short pulse radar type 1, the same waveform is used a minimum of 30 times. If more than 30
       waveforms are used for short pulse radar types 2 through 4, then each additional waveform must also
       be unique and not repeated from the previous waveforms.


       If more than 30 waveforms are used for Short Pulse Radar Type 1, then each additional waveform is
       generated with Test B and must also be unique and not repeated from the previous waveforms in Tests
       A or B.


       The aggregate is the average of the percentage of successful detections of short pulse radar types 1-4.

3 Calibration Setup and DFS Test Results
3.1 Calibration of Radar Waveform
3.1.1 Radar Waveform Calibration Procedure
         The Interference Radar Detection Threshold Level is (-62dBm) + (0) [dBi]+ 1 dB= -61dBm that had
         been taken into account the output power range and antenna gain. The following equipment setup
         was used to calibrate the radiated Radar Waveform. A vector signal generator was utilized to
         establish the test signal level for radar type 0. During this process there were no transmissions by
         either the Master or Client Device. The spectrum analyzer was switched to the zero span (Time
         Domain) at the frequency of the Radar Waveform generator. Peak detection was used. The spectrum
         analyzer resolution bandwidth (RBW) and video bandwidth (VBW) were set to 3 MHz to measure the
         type 0 radar waveform. The spectrum analyzer had offset to compensate and RF cable loss. The
         vector signal generator amplitude was set so that the power level measured at the spectrum analyzer
         was (-62dBm) + (0) [dBi]+ 1 dB= -61 dBm. Capture the spectrum analyzer plots on short pulse radar
         waveform.

            FCC DFS Test Report                                                         Report No. : FZ952704


3.2 In-Service Monitoring: Channel Move Time, Channel Closing
    Transmission Time and Non-Occupancy Period
3.2.1 Limit of In-Service Monitoring
                The EUT has In-Service Monitoring function to continuously monitor the radar signals, If radar is
         detected, it must leave the channel (Shutdown). The Channel Move Time to cease all transmissions
         on the current Channel upon detection of a Radar Waveform above the DFS Detection Threshold
         within 10 sec. The total duration of 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 Channel changes (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.
                Non-Occupancy Period time is 30 minute during which a Channel will not be utilized after a
         Radar Waveform is detected on that Channel. The non-associated Client Beacon Test is during the 30
         minutes observation time. The EUT should not make any transmissions in the DFS band after EUT
         power up.

3.2.2 Test Procedures
         1.    The radar pulse generator is setup to provide a pulse at frequency that the Master and Client are
               operating. A type 0 radar pulse with a 1us pulse width and a 1428 us PRI is used for the testing.
         2.    The vector signal generator is adjusted to provide the radar burst (18 pulses) at a level of
               approximately -62dBm at the antenna of the Master device.
         3.    A trigger is provided from the pulse generator to the DFS monitoring system in order to capture
               the traffic and the occurrence of the radar pulse.
         4.    A U-NII device operating as a Client Device will associate with the Master at Channel. The
               MPEG file “TestFile.mpg” specified by the FCC is streamed from the “file computer” through the
               Master to the Client Device and played in full motion video using Media Player Classic Ver.
               6.4.8.6 in order to properly load the network for the entire period of the test.
         5.    When a radar Burst with a level equal to the DFS Detection Threshold + 1dB is generated on the
               Operating Channel of the U-NII device. At time T0 the Radar Waveform generator sends a Burst
               of pulse of the radar waveform at Detection Threshold + 1dB.
         6.    Observe the transmissions of the EUT at the end of the radar Burst on the Operating Channel.
               Measure and record the transmissions from the EUT during the observation time (Channel Move
               Time). One 12 seconds plot is reported for the Short Pulse Radar Types 0. The plot for the Short
               Pulse Radar Types start at the end of the radar burst. The Channel Move Time will be calculated
               based on the zoom in 600ms plot of the Short Pulse Radar Type.
         7.    Measurement of the aggregate duration of the Channel Closing Transmission Time method.
               With the spectrum analyzer set to zero span tuned to the center frequency of the EUT operating
               channel at the radar simulated frequency, peak detection, and max hold, the dwell time per bin is
               given by: Dwell (0.4ms)= S (12000ms) / B (30000); where Dwell is the dwell time per spectrum
               analyzer sampling bin, S is the sweep time and B is the number of spectrum analyzer sampling
               bins. An upper bound of the aggregate duration of the intermittent control signals of Channel
               Closing Transmission Time is calculated by: C (ms)= N X Dwell (0.4 ms); where C is the Closing
               Time, N is the number of spectrum analyzer sampling bins (intermittent control signals) showing
               a U-NII transmission and Dwell is the dwell time per bin.
         8.    Measure the EUT for more than 30 minutes following the channel move time to verify that no
               transmissions or beacons occur on this Channel.
