Report No.: 1580268R-RF-FCC-DFS 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. 1.3. UNII Device Description The UUT operates in the following band: 5470-5725 MHz The UUT is a Client Device that does not have radar detection capability and ad-hoc function. The highest gain antenna assembly utilized with the EUT has a maximum gain of 2.65dBi in 5GHz frequency band. The 50-ohm Tx/Rx antenna port is connected to the test system to perform conducted tests. TPC is not required since the maximum EIRP is less than 500mW (27dBm). The UUT utilizes 802.11a/n IP based architecture. Two nominal channel bandwidths, 20 MHz and 40MHz are implemented. WLAN traffic is generated by streaming the video file “TestFile.mp2” from the Master device to the Slave device in full motion video mode using the “Nero Show Time 3” with the V3.0.1.3 Codec package. The master device is a Cisco 802.11a/b/g/n Access Point. The Cisco Access Point FCC ID: LDK102061. The UUT is a client device without radar detection therefore the interference threshold level is not required. Statement: Information regarding the parameters of the detected Radar Waveforms is not available to the end user. Page: 6 of 24

Report No.: 1580268R-RF-FCC-DFS DFS Detection Thresholds for Master Devices and Client Devices With Radar Detection Maximum Transmit Power Value (see note) EIRP ≥ 200 milliwatt -64 dBm EIRP < 200 milliwatt and power spectral -62 dBm density < 10 dBm/MHz EIRP < 200 milliwatt that do not meet the -62 dBm 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. DFS Response requirement values Parameter Value Non-Occupancy Period Minimum 30 minutes Channel Availability Check Time 60 Seconds 10 Seconds Channel Move Time (See Note1) 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. Page: 10 of 24

Report No.: 1580268R-RF-FCC-DFS 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. For example if in Short Pulse Radar Type 1 Test B a PRI of 3066 usec is selected, the number of pulses would be = Roundup ⋅ ⋅ Page: 11 of 24

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 – 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 No.: 1580268R-RF-FCC-DFS 1.7. Client Device requreiment 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 and d) through f) of section 5.1.1 apply. 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. Page: 14 of 24

Report No.: 1580268R-RF-FCC-DFS 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 3MHz and 3 MHz. The signal generator amplitude was set so that the power level measured at the spectrum analyzer was -61dBm due to the interference threshold level is not required.

Report No.: 1580268R-RF-FCC-DFS 2. Channel Move Time and Channel Closing Transmission Time 2.1. Test Procedure These tests define how the following DFS parameters are verified during In-Service Monitoring; Channel Closing Transmission Time and Channel Move Time. The steps below define the procedure to determine the above mentioned parameters when a radar burst with a level -61dBm is generated on the operating channel of the U-NII device. A U-NII device operating as a Client device will associate with the Master device at 5500MHz. During the in-service monitoring detection probability and channel moving tests the system was configured with a streaming video file from the master device (sourced by the PC connected to the master device via an Ethernet interface) to the client device. The streamed file was the “FCC” test file and the client device was using Media Player Classic as required by FCC Part 15 Subpart E. 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 spectrum analyzer 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. 2.2. Test Requirement Parameter Value Channel Move Time 10 Seconds Channel Closing Transmission Time 200 milliseconds + approx. 60 milliseconds over remaining 10 seconds period 2.3. Uncertainty ± 1ms.
