 3.2. DFS Devices Requirements

 Per FCC KDB 905462 D02 UNII DFS Compliance Procedures New Rules v02 the following are
 the requirements for 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.
 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.

 Channel Move Time and Channel Closing Transmission Time requirements are listed in the
 following table.
 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
 Channel Closing Transmission Time                   milliseconds over remaining 10 second period.
                                                     See Notes 1 and 2.

                                                     Minimum 100% of the U-NII 99% transmission
 U-NII Detection Bandwidth
                                                     power bandwidth. See Note 3.
 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.

 3.3. DFS Detection Threshold Values
 The DFS detection thresholds are defined for Master devices and Client Devices with In-service
 monitoring. These detection thresholds are listed in the following table.
 Maximum Transmit Power                                                      Value
                                                                             (See Notes 1, 2, and 3)
 EIRP ≥ 200 milliwatt                                                        -64 dBm
 EIRP < 200 milliwatt and                                                    -62 dBm
 power spectral density < 10 dBm/MHz
 EIRP < 200 milliwatt that do not meet the power spectral density            -64 dBm
 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.
 Note 3: EIRP is based on the highest antenna gain. For MIMO devices refer to KDB Publication
 662911 D01.

                 Table 3-8: Parameters for Frequency Hopping Radar Waveforms

 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 selected 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 – 5724MHz. 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.

 5.2. Radar Waveform Calibration

 5.2.1.Calibration Setup
 The conducted test setup was used for this calibration testing. Figure 3-2 shows the typical test
 setup.




                                 Figure 3-2: Conducted Test Setup

 5.2.2.Calibration Procedure
 The Interference Radar Detection Threshold Level is (-64dBm) + (0) [dBi] + 1 dB= -63 dBm that had
 been taken into account the output power range and antenna gain. The above equipment setup was
 used to calibrate the conducted Radar Waveform. A vector signal generator was utilized to establish
 the test signal level for each radar type. During this process there were replace 50ohm terminal form
 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 used. The spectrum analyzer resolution bandwidth (RBW) and video
 bandwidth (VBW) were set to at least 3MHz. The vector signal generator amplitude was set so that
 the power level measured at the spectrum analyzer was (-64dBm) + (0) [dBi] + 1 dB= -63dBm.
 Capture the spectrum analyzer plots on short pulse radar types, long pulse radar type and hopping
 radar waveform.

 5.4. In-Service Monitoring for Channel Move Time, Channel Closing Transmission
      Time and Non-Occupancy Period Measurement

 5.4.1.Test Limit
 The EUT has In-Service Monitoring function to continuously monitor the radar signals. If the radar is
 detected, 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 260ms, consisting of data
 signals and the aggregate of control signals, by a U-NII device during the Channel Move Time. The
 Non-Occupancy Period time is 30 minute during which a Channel will not be utilized after a Radar
 Waveform is detected on that Channel.



 5.4.2.Test Procedure Used
 1. The test should be performed with Radar Type 0. The measurement timing begins at the end of
 the Radar Type 0.
 2. When the radar burst with a level equal to the DFS Detection Threshold + 1dB is generated on the
 Operating Channel of the U-NII device. A U-NII device operating as a Master Device will associate
 with the Client Device at Channel. 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 Detection Threshold + 1dB.
 2. 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).
 3. 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 (1.5ms) = S (12 sec) / B (8000); 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: 80MHz: C = N X Dwell; where C is the Closing Time, N is the number of spectrum
 analyzer sampling bins showing a U-NII transmission and Dwell is the dwell time per bin.
 4. 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.
