1.2.   Standard Requirement
       FCC Part 15.407:
       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 30dBm. A TPC mechanism is not required for
       systems with an E.I.R.P. of less than 500mW.
       U-NII devices operating in the 5.25-5.35 GHz and 5.47-5.725 GHz bands shall employ a DFS
       radar detection mechanism to detect the presence of radar systems and to avoid co-channel
       operation with radar systems.

1.3.   UNII Device Description
       1.   The EUT operates in the following DFS band:
            (1) 5250-5350 MHz
            (2) 5470-5725 MHz


       2.   The U-NII device maximum power is 18.92dBm (E.I.R.P).
            Below are the available 50 ohm antenna assemblies and their corresponding gains. 0dBi
            gain was used to set the -63 dBm threshold level (-64dBm +1 dB) during calibration of the
            test setup.


       3.   WLAN traffic is generated by the test software “Iperf.exe” from the Master device to the
            Slave device in the transfer data rate >17%.


       4.   For the 5250-5350 MHz and 5470-5725 MHz bands, the Master device provides, on
            aggregate, uniform loading of the spectrum across all devices by selecting an operating
            channel among the available channels using a random algorithm.

1.6.    DFS Detection Thresholds
  (1) Interference Threshold value, Master or Client incorporating In-Service Monitoring
  Maximum Transmit Power                            Value (see note)
    200 milliwatt                                  -64dBm
  EIRP < 200 milliwatt and
                                                    -62dBm
  power spectral density < 10 dBm/MHz
  EIRP < 200 milliwatt that do not meet the
                                                       -64dBm
  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.

   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.

1.7.     Radar Test Waveforms
  This section provides the parameters for required test waveforms, minimum percentage of successful
detections, and the minimum number of trials that must be used for determining DFS conformance. 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.
  (1) Short Pulse Radar Test Waveforms




  A minimum of 30 unique waveforms are required for each of the Short Pulse Radar Types 2 through 4. 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 parameters for this waveform are randomly chosen. Thirty unique waveforms are required for the long
pulse radar test signal. If more than 30 waveforms are used for the long pulse radar test signal, then each
additional waveform must also be unique and not repeated from the previous waveforms.

Each waveform is defined as follows:
 1) The transmission period for the Long Pulse Radar test signal is 12 seconds.
  2) There are a total of 8 to 20 Bursts in the 12 second period, with the number of Bursts being randomly chosen.
    This number is Burst_Count.
  3) Each Burst consists of 1 to 3 pulses, with the number of pulses being randomly chosen. Each Burst within
    the 12 second sequence may have a different number of pulses.
  4) The pulse width is between 50 and 100 microseconds, with the pulse width being randomly chosen. Each
    pulse within a Burst will have the same pulse width. Pulses in different Bursts may have different pulse
    widths.
  5) Each pulse has a linear frequency modulated chirp between 5 and 20 MHz, with the chirp width being
    randomly chosen. Each pulse within a transmission period will have the same chirp width. The chirp is
    centered on the pulse. For example, with a radar frequency of 5300 MHz and a 20 MHz chirped signal, the
    chirp starts at 5290 MHz and ends at 5310 MHz.
  6) If more than one pulse is present in a Burst, the time between the pulses will be between 1000 and 2000
    microseconds, with the time being randomly chosen. If three pulses are present in a Burst, the time between
    the first and second pulses is chosen independently of the time between the second and third pulses.
  7) The 12 second transmission period is divided into even intervals. The number of intervals is equal to
    Burst_Count. Each interval is of length (12,000,000 / Burst_Count) microseconds. Each interval contains
    one Burst. The start time for the Burst, relative to the beginning of the interval, is between 1 and [(12,000,000
    / Burst_Count) – (Total Burst Length) + (One Random PRI Interval)] microseconds, with the start time being
    randomly chosen. The step interval for the start time is 1 microsecond. The start time for each Burst is
    chosen independently.
A representative example of a Long Pulse radar test waveform:
  1) The total test signal length is 12 seconds.
  2) 8 Bursts are randomly generated for the Burst_Count.
  3) Burst 1 has 2 randomly generated pulses.
  4) The pulse width (for both pulses) is randomly selected to be 75 microseconds.
  5) The PRI is randomly selected to be at 1213 microseconds.
  6) Bursts 2 through 8 are generated using steps 3 – 5.
  7) Each Burst is contained in even intervals of 1,500,000 microseconds. The starting location for Pulse 1, Burst
    1 is randomly generated (1 to 1,500,000 minus the total Burst 1 length + 1 random PRI interval) at the
    325,001 microsecond step. Bursts 2 through 8 randomly fall in successive 1,500,000 microsecond intervals
    (i.e. Burst 2 falls in the 1,500,001 – 3,000,000 microsecond range).

  For the Frequency Hopping Radar Type, the same Burst parameters are used for each waveform. The
hopping sequence is different for each waveform and a 100-length segment is selected1 from the hopping
sequence defined by the following algorithm:
  The first frequency in a hopping sequence is selected randomly from the group of 475 integer frequencies from
5250 – 5724 MHz. Next, the frequency that was just chosen is removed from the group and a frequency is
randomly selected from the remaining 474 frequencies in the group. This process continues until all 475
frequencies are chosen for the set. For selection of a random frequency, the frequencies remaining within the
group are always treated as equally likely.

1.8.    Radar Waveform Calibration
  The following equipment setup was used to calibrate the conducted radar waveform. A spectrum
analyzer was used to establish the test signal level for each radar type. During this process there were
replace 50ohm terminal from master and client device and 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 utilized. The spectrum analyzer resolution
bandwidth (RBW) and video bandwidth (VBW) were set to 1MHz and 1MHz.


  The signal generator amplitude was set so that the power level measured at the spectrum analyzer
was -63dBm due to the interference threshold level is not required.

2.     In-Service Monitoring for Channel Move Time and Channel Closing
       Transmission Time and Non-Occupancy Period
2.1.   Test Procedure
       The EUT was tested according to U-NII test procedure of KDB905462 D02 for compliance to
       FCC 47CFR 15.407 requirements.

       These tests define how the following DFS parameters are verified during In-Service
       Monitoring; Channel Closing Transmission Time, Channel Move Time, and Non-Occupancy
       Period.. The steps below define the procedure to determine the above mentioned parameters
       when a radar Burst with a level equal to the DFS Detection Threshold + 1dB (-63dBm) is
       generated on the Operating Channel of the U-NII device.

       A U-NII device operating as a Client Device will associate with the UUT (Master) at 5300MHz/
       5510MHz and 5630MHz.

       Stream the MPEG test file from the Master Device to the Client Device on the selected
       Channel for the entire period of the test.

       At time T0 the Radar Waveform generator sends a Burst of pulses for each of the radar types
       at -63dBm.

       Observe the transmissions of the UUT at the end of the radar Burst on the Operating Channel
       for duration greater than 10 seconds. Measure and record the transmissions from the UUT
       during the observation time (Channel Move Time). Compare the Channel Move Time and
       Channel Closing Transmission Time results to the limits defined in the DFS Response
       requirement values table.

       Measure the UUT for more than 30 minutes following the channel close/move time to verify
       that the UUT does not resume any transmissions on this Channel.


2.2.   Test Requirement
          Parameter                        Value
          Channel Move Time                10 Seconds
          Channel Closing                  200 milliseconds + approx. 60 milliseconds
