Report No.: HCT-R-1603-F021 Page of 23 Model: LG-H850 Channel Move Time and Channel Closing Transmission Time requirements are listed 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 milliseconds over Channel Closing Transmission Time Remaining 10 second period. See Notes 1 and 2. Minimum 100 % of the U-NII U-NII Detection Bandwidth 99 % transmission 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 Channell 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. Note3: 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 No.: HCT-R-1603-F021 Page of 23 Model: LG-H850 7.3 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. Value Maximum Transmit Power (See Notes 1 and 2) ≥ 200 milliwatt -64 dBm < 200 milliwatt -62 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.

Report No.: HCT-R-1603-F021 Page of 23 Model: LG-H850 7.5 TEST AND MEASUREMENT SYSTEM General Test Setup Procedure: 1. The EUT was operating 802.11n_HT40 mode (MCS0) during the test. 2. Connect FCC approved Master AP to a network, via wired Ethernet, that allows connection to an FTP server. 3. Associate the EUT with the Master AP. 4. Launch the FTP application on the EUT. 5. Connect to the FTP server application to the FTP server hosting the file 6. Initiate an FTP download of the file from the host. 7. Monitor the channel loading during transfer. 8. Reduce the maximum allowed data rate for the Master AP, using the AP’s GUI interface. 9. Repeat steps 5-7 until the channel loading is as close to 20 % as possible. 10. Record the data rate setting on the Master AP and the channel loading. 11. While the system is performing an FTP transfer using the settings form item 9 above, perform the Channel Closing Transmission Time and Channel Move Time Measurements as required by KDB905462 D02(10/16/2015) using a conducted test. PROCEDURE The KDB905462 D02(10/16/2015) describes a radiated test setup and a conducted test setup. A radiated test setup was used for this testing. Figure 3-1 shows the typical test setup. Each one channel selected between 5260 and 5320 MHz, 5500 and 5720 is chosen for the testing. Figure 3-1. Conducted Test Setup for DFS F-TP22-03 (Rev.00) HCT CO.,LTD. / 23 FCC ID: ZNFH850

Report No.: HCT-R-1603-F021 Page of 23 Model: LG-H850 1. The radar pulse generator is setup to provide a pulse at the frequency that the Master and Client are operating. A Type 0 radar pulse with a 1 μs pulse width and a 1428 μs PRI is used for the testing. 2. The vector signal generator is adjusted to provide the radar burst (18 pulses) at a level of approximately -62 dBm at the antenna of the Master device. 3. The Client Device (EUT) is set up per the diagram in Figure 3-1 and communications between the Master device and the Client is established. 4. The MPEG file specified by the FCC (”6½ Magic Hours”) is streamed from the “file computer” through the Master to the Slave Device and played in full motion video using Media Player Classic Ver.6.4.8.6 in order to properly load the network. 5. The spectrum analyzer is set to record about 15 sec window to any transmissions occurring up to and after 10 sec. 6. The system is again setup and the monitoring time is shortened in order to capture the Channel Closing Transmission Time. This time is measured to insure that the Client ceases transmission within 200 ms and the aggregate of emissions occurring after 200 ms up to 10 sec do not exceed 60 ms. (Note: the channel may be different since the Master and Client have changed channels due to the detection of the initial radar pulse.) 7. After the initial radar burst the channel is monitored for 30 minutes to insure no transmissions or beacons occur. A second monitoring setup is used to verify that the Master and Client have both moved to different channels. SYSTEM CALIBRATION A-50-ohm load is connected in place of the spectrum analyzer, and the spectrum analyzer is connected to a coaxial cable. The signal generator is set to CW mode. The amplitude of the signal generator is adjusted to yield a level of - 62 dBm as measured on the spectrum analyzer. Without changing any of the instrument settings, the spectrum analyzer is reconnected to the common port of the spectrum analyzer combiner or divider. The spectrum analyzer displays the level of the signal generator higher than the client TX level. Because we can not search the signal generator in the spectrum analyzer when the signal generator level is - 62 dBm. The spectrum analyzer will still indicate the level higher than the client TX level. F-TP22-03 (Rev.00) HCT CO.,LTD. / 23 FCC ID: ZNFH850

Report No.: HCT-R-1603-F021 Page of 23 Model: LG-H850 7.6 DESCRIPTION OF EUT The EUT operates over the 5260 MHz - 5320 MHz and 5500 MHz - 5720 MHz ranges. The EUT is a slave device without radar detection. The EUT antenna has a gain of -6.22dBi in 5260 MHz - 5320 MHz band and -7.39dBi in 5500 MHz- 5720 MHz band. The highest power level within these bands in 7.25 dBm EIRP in the 5260 MHz - 5320 MHz band and 6.11 dBm EIRP in the 5500 MHz – 5720 MHz band. The EUT one transmitter/receiver chain connected to a coaxial cable to perform conducted tests. TPC is not required since the maximum EIRP is less than 500 mW. The EUT utilizes the 802.11a/n/ac architecture. The nominal channel bandwidth is implemented: 20 MHz, 40 MHz,80 MHz F-TP22-03 (Rev.00) HCT CO.,LTD. / 23 FCC ID: ZNFH850
