      802.11 devices it is suggested to select frequencies in each of the bonded 20 MHz channels and the channel
      center frequency.

                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 662911D01.

     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 is used and for each
             frequency step the minimum percentage of detection is 90 percent. Measurements are
             performed with no data traffic.

The parameters for this waveform are randomly chosen. Thirty unique waveforms are required for the Long Pulse Radar
Type waveforms. If more than 30 waveforms are used for the Long Pulse Radar Type waveforms, then each additional
waveform must also be unique and not repeated from the previous waveforms.

4.6   Test Procedure

A spectrum analyzer is used as a monitor that verifies the EUT’s status, which includes the Channel Closing
Transmission Time and the Channel Move Time. The Spectrum analyzer is used to monitor the equipment
under test (EUT) does not transmit on the same channel during the Non-Occupied Period after the radar
detection.

5     Test Results

5.1    Description of EUT

The EUT operates in 5230-5350 MHz and 5470-5725 MHz range in client Mode.

The rated output power of master device is <23 dBm (EIRP), and the PSD is <10 dBm/MHz, the required
radiated threshold at antenna port is -64 dBm.

WLAN traffic is generated by streaming the data with iperf software.

6     Channel Move Time and Channel Closing Transmission Time

6.1    Test Procedure

Perform one of the type 0 short pulse radar waveform

The aggregate channel closing transmission time is calculated as follows:

Aggregate Transmission Time = N * Dwell Time

N is the number of spectrum analyzer bins showing a device transmission
Dwell Time is the dwell time per bin (i.e. Dwell Time = S/B, S is the sweep time and B is the number of bin, i.e.
8192)
