    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.


  The EUT was tested according to the following specification:
   905462 D02 UNII DFS Compliance Procedure New Rules v02
   905462 D03 UNII Client Without Radar Detection New Rules v01r02

2.3. Requirements of 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 shut down (rather than moving channels), no beacons should appear.

 2.4. 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 milliseconds over
     Channel closing transmission time
                                                               remaining 10 second period. See Notes 1 and 2.
     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.



2.5. DFS detection thresholds
   Below provides the DFS Detection Thresholds for Master Devices as well as Client Devices incorporating
   In-Service Monitoring.

     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.

 Note 1: As the EUT is a Client Device without Radar Detection, only one type of radar pulse is required for testing.
         The Radar Pulse type 0 was used to evaluate the Client device to measure the Channel Move Time
         and the Channel Closing Transmission Time.
 Note 2: This report was applied Short Pulse Radar Type 0.

 3.1. Setup for Client with injection at the Master
  The setup method is shown below diagram. The method according to the 905462 D02 UNII DFS Compliance
  Procedure New Rules v02 - section 7.2




 3.2. Spectrum analyzer setting parameter
  The setting parameter is shown below and it according to the 905462 D02 UNII DFS Compliance Procedure New
  Rules v02 - section 7.5
     1)   RBW /VBW ≥ 3MHz
     2)   Detector = Peak
     3)   Span = zero span
     4)   Sweep time ≥ 12s


 3.3. Conducted test procedure
   1) One frequency will be chosen from the Operating Channels of the UUT within the 5250-5350 MHz or 5470-5725
       MHz bands.
   2) The Client Device (EUT) is set up the above diagram and communications between the Master device and the
       Client is established.
   3) Stream the channel loading test file from the Master Device to the Client Device on the test Channel for the entire
       period of the test. (The MPEG file specified by the FCC (“6 ½ Magic Hours”))
   4) An additional 1 dB is added to the radar test signal to ensure it is at or above the DFS Detection Threshold,
       accounting for equipment variations/errors.
   5) Observe the transmissions of the UUT at the end of the Burst on the Operating Channel for duration greater than
       12 seconds for Radar Type 0 to ensure detection occurs.
   6) After the initial radar burst the channel is monitored for 30 minutes to ensure no transmissions or beacons occur.
       A second monitoring setup is used to verify that the Master and Client have both moved to different channels.

       Note 2: 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 3: 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.
