FCC DFS Test Report Report No. : FZ273144-14 3 Dynamic Frequency Selection (DFS) Test Result 3.1 General DFS Information 3.1.1 DFS Parameters Table D.1: DFS requirement values Parameter Value Non-occupancy period Minimum 30 minutes Channel Availability Check Time 60 seconds Channel Move Time 10 seconds (Note 1). Channel Closing Transmission Time 200 milliseconds + an aggregate of 60 milliseconds over remaining 10 second periods. (Notes 1 and 2). U-NII Detection Bandwidth Minimum 100% of the 99% power bandwidth (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 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. Table D.2: Interference threshold values Maximum Transmit Power Value (see note) EIRP ≥ 200 mW -64 dBm EIRP < 200 mW and PSD < 10dBm/MHz -62 dBm EIRP < 200 mW and PSD >= 10dBm/MHz -64 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. Note3: EIRP is based on the highest antenna gain.

A minimum of 30 unique waveforms are required for each of the short pulse radar types 1 through 4. If more than 30 waveforms are used for short pulse radar types 1 through 4, then each additional waveform must also be unique and not repeated from the previous waveforms. The aggregate is the average of the percentage of successful detections of short pulse radar types 1-4. 3.2.2 Long Pulse Radar Test Waveform Minimum Pulse Chirp Number of Radar Number of Percentage of Minimum Width Width PRI (µsec) Pulses Type Bursts Successful Trials (µsec) (MHz) per Burst Detection 5 50-100 5-20 1000-2000 1-3 8-20 80% 30 Each waveform is defined as follows:  The transmission period for the Long Pulse Radar test signal is 12 seconds.  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.  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.  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.  Each pulse has a linear FM 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.  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 SPORTON INTERNATIONAL INC.

FCC DFS Test Report Report No. : FZ273144-14 between the first and second pulses is chosen independently of the time between the second and third pulses.  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. 3.2.3 Frequency Hopping Radar Test Waveform Minimum Pulse Hopping Radar PRI Pulses Hopping Percentage of Minimum Width Sequence Type (µsec) per Hop Rate (kHz) Successful Trials (µsec) Length (ms) Detection 6 1 333 9 0.333 300 70% 30 The FCC Type 6 waveform uses a static waveform with 100 bursts in the instruments ARB. In addition, the RF list mode is operated with a list containing 100 frequencies from a randomly generated list and it had be ensured that at least one of the random frequencies falls into the UNII Detection Bandwidth of the DUT. Each burst from the waveform file initiates a trigger pulse at the beginning that switches the RF list from one item to the next one. 3.2.4 DFS Threshold Level DFS Threshold Level DFS Threshold level: -63 dBm at the antenna connector in front of the antenna The Interference Radar Detection Threshold Level is is -64 dBm + 0 [dBi] + 1 dB = -63 dBm. That had been taken into account the output power range and antenna gain. 3.2.5 Calibration Setup Client Radiated Calibration Setup SPORTON INTERNATIONAL INC.

And zoom-in a 60 ms plot verified channel closing time for the aggregate transmission time starting from 200ms after the end of the radar signal to the completion of the channel move. Verified during In-Service Monitoring; Non-Occupancy Period. Client Device will associate with the EUT. Observe the transmissions of the EUT at the end of the radar Burst on the Operating Channel for duration greater than 10 seconds. Measure and record the transmissions from the EUT during the observation time (Non-Occupancy Period). Compare the Non-Occupancy Period limits. SPORTON INTERNATIONAL INC.
