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. DFS Response requirement values Parameter Value Non-occupancy period Minimum 30 minutes Channel Availability Check Time 60 seconds Channel Move Time 10 seconds See Note 1. Channel Closing Transmission 200 milliseconds + an aggregate of 60 milliseconds over remaining 10 Time second period. See Notes 1 and 2. Minimum 100% of the UNII 99% transmission power bandwidth See U-NII Detection 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 facilitating 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.

Report Number: WAP-19052921-LC-FCC-IC-DFS-G4 Page 13 of 27 Product: Vehicle Infotainment System Model Number: SYNC-G4 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 FM chirp between 5 and 20 MHz, with the chirp width being randomly chosen. Each pulse within a Burst will have the same chirp width. Pulses in different Bursts may have different chirp widths. 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 s9tart 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).

The hopping sequence is different for each waveform and a 100-length segment is selected 1 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.

Report Number: WAP-19052921-LC-FCC-IC-DFS-G4 Page 15 of 27 Product: Vehicle Infotainment System Model Number: SYNC-G4 7.2 Dynamic Frequency Selection (DFS) Applicability 7.2.1 Requirement A U-NII network will employ a DFS function to detect signals from radar systems and to avoid co-channel operation with these systems. This applies to the 5250-5350 MHz and/or 5470-5725 MHz bands.1 Within the context of the operation of the DFS function, a U-NII device will operate in either Master Mode or Client Mode. U-NII devices operating in Client Mode can only operate in a network controlled by a UNII device operating in Master Mode. Following tables shown below summarize the DFS testing applicability. Applicability of DFS Requirements Prior to Use of a Channel Applicability of DFS requirements during normal operation 7.2.2 Conclusion EUT is client device without radar detection function. Only the Channel Closing Transmission Time and Channel Move time testing are required. The testing shall be done using the widest BW mode.

The aggregate duration of control signals will not count quiet periods in between transmissions. The channel closing transmission time shall be less than (200 milliseconds + an aggregate of 60 milliseconds) over remaining 10 second period Channel Move Time After a radar's presence is detected, all transmissions shall cease on the operating channel within 10 seconds. Transmissions during this period shall consist of normal traffic for a maximum of 200 ms after detection of the radar signal. In addition, intermittent management and control signals can be sent during the remaining time to facilitate vacating the operating channel. 7.3.2 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 no transmissions by either the Master or Client Device. The spectrum analyzer was switched to the zero span (Time Domain) mode at the frequency of the Radar Waveform generator. Peak detection was utilized.

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 is generated on the Operating Channel of the U-NII device. UUT operating as a Client Device will associate with the (Master) at Mid Channel. DFS testing while the System testing was performed with the designated MPEG test file that streams full motion video at 30 frames per second from the Master to the Client IP based system At time T0 the Radar Waveform generator sends a Burst of pulses for each of the radar types. 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. Channel Closing Transmission Time- Measurement A type 1 waveform was introduced to the EUT and the Spectrum Analyzer sweep time was set to 1s for monitoring and capturing the plot. A LabVIEW program was created to collect trace data and capturing the plot. The program will calculate the channel closing time base on the spectrum analyzer result. The result will be calculated based on FCC procedure. C= N*Dwell 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. Dwell= S/B Where Dwell is the dwell time per spectrum analyzer sampling bin, S is the sweep time and B is the number 0f spectrum analyzer sampling bins.

Report Number: WAP-19052921-LC-FCC-IC-DFS-G4 Page 20 of 27 Product: Vehicle Infotainment System Model Number: SYNC-G4 7.3.4 DFS Test Setup Test Setup Block Diagram The radio was set at the center channel frequency of tested Channel. A FCC approved Master device – (FCC ID: Q87-EA8300) AP was used to link with DUT device. 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. The rated output power of the Master unit is > 23 dBm (EIRP). Therefore, the required interference threshold is – 64 dBm. After correction for procedural adjustment, the required radiated threshold at the antenna port is -64 + 1 = -63 dBm. The calibrated radiated DFS detection threshold level is set to -64 dBm. The tested level is lower than the required level hence it provides margining to the limit. 7.3.5 DFS Test Results BW / Channel Test Item Test Result Limit Verdict 11n-5320MHz Channel Move Time ＜ 10s ＜ 10s Pass 11n-5600MHz Channel Move Time ＜ 10s ＜ 10s Pass 11ac-5290MHz Channel Move Time ＜ 10s ＜ 10s Pass 11ac-5530MHz Channel Move Time ＜ 10s ＜ 10s Pass 11n-5320MHz Channel Closing Transmission Time 8ms ＜ 260ms Pass 11n-5600MHz Channel Closing Transmission Time 9ms ＜ 260ms Pass 11ac-5290MHz Channel Closing Transmission Time 6.005ms ＜ 260ms Pass 11ac-5530MHz Channel Closing Transmission Time 6ms ＜ 260ms Pass 11n-5320MHz Non-Occupancy Period ≥ 30min ≥ 30 min Pass 11n-5600MHz Non-Occupancy Period ≥ 30min ≥ 30 min Pass 11ac-5290MHz Non-Occupancy Period ≥ 30min ≥ 30 min Pass 11ac-5530MHz Non-Occupancy Period ≥ 30min ≥ 30 min Pass Electromagnetic Compatibility 1261 Puerta Del Sol Radio Frequency San Clemente, CA, 92673 Product Certification +1 (949) 393-1123 International Approval www.vista-compliance.com
