(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 8 of 32 UL VERIFICATION SERVICES INC.

REPORT NO: 15I20405 – E7 DATE: APRIL 21, 2015 MODEL NUMER: LG-US991, US991, LGUS991 FCC ID: ZNFUS991 SYSTEM OVERVIEW The short pulse and long pulse signal generating system utilizes the NTIA software. The Vector Signal Generator has been validated by the NTIA. The hopping signal generating system utilizes the CCS simulated hopping method and system, which has been validated by the DoD, FCC and NTIA. The software selects waveform parameters from within the bounds of the signal type on a random basis using uniform distribution. The short pulse types 1, 2, 3 and 4, and the long pulse type 5 parameters are randomized at run-time. The hopping type 6 pulse parameters are fixed while the hopping sequence is based on the August 2005 NTIA Hopping Frequency List. The initial starting point randomized at run-time and each subsequent starting point is incremented by 475. Each frequency in the 100-length segment is compared to the boundaries of the EUT Detection Bandwidth and the software creates a hopping burst pattern in accordance with Section 7.4.1.3 Method #2 Simulated Frequency Hopping Radar Waveform Generating Subsystem of KDB 905462 D02. The frequency of the signal generator is incremented in 1 MHz steps from FL to FH for each successive trial. This incremental sequence is repeated as required to generate a minimum of 30 total trials and to maintain a uniform frequency distribution over the entire Detection Bandwidth. The signal monitoring equipment consists of a spectrum analyzer. The aggregate ON time is calculated by multiplying the number of bins above a threshold during a particular observation period by the dwell time per bin, with the analyzer set to peak detection and max hold. SYSTEM CALIBRATION A 50-ohm load is connected in place of the spectrum analyzer, and the spectrum analyzer is connected to a horn antenna via a coaxial cable, with the reference level offset set to (horn antenna gain – coaxial cable loss). The signal generator is set to CW mode. The amplitude of the signal generator is adjusted to yield a level of –64 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/Divider. The Reference Level Offset of the spectrum analyzer is adjusted so that the displayed amplitude of the signal is –64 dBm. The spectrum analyzer displays the level of the signal generator as received at the antenna ports of the Master Device. The interference detection threshold may be varied from the calibrated value of –64 dBm and the spectrum analyzer will still indicate the level as received by the Master Device.

REPORT NO: 15I20405 – E7 DATE: APRIL 21, 2015 MODEL NUMER: LG-US991, US991, LGUS991 FCC ID: ZNFUS991 ADJUSTMENT OF DISPLAYED TRAFFIC LEVEL A link is established between the Master and Slave and the distance between the units is adjusted as needed to provide a suitable received level at the Master and Slave devices. The video test file is streamed to generate WLAN traffic. The monitoring antenna is adjusted so that the WLAN traffic level, as displayed on the spectrum analyzer, is at lower amplitude than the radar detection threshold.

REPORT NO: 15I20405 – E7 DATE: APRIL 21, 2015 MODEL NUMER: LG-US991, US991, LGUS991 FCC ID: ZNFUS991 5.1.4. DESCRIPTION OF EUT For FCC the EUT operates over the 5250-5350 MHz and 5470-5725 MHz ranges. For IC the EUT operates over the 5250-5350 MHz and 5470-5725 MHz ranges, excluding the 5600-5650 MHz range. The EUT is a Slave Device without Radar Detection. The highest power level within these bands is 12.9 dBm EIRP in the 5250-5350 MHz band and 13.09 dBm EIRP in the 5470-5725 MHz band. The only antenna assembly utilized with the EUT has a gain of 2.35 dBi. The rated output power of the Master unit is > 23dBm (EIRP). Therefore the required interference threshold level is –64 dBm. After correction for procedural adjustments, 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 a margin to the limit. The EUT uses one transmitter/receiver chain connected to an antenna to perform radiated tests. WLAN traffic that meets or exceeds the minimum required loading was generated by transferring a data stream from the controller/server PC to the EUT using iPerf version 2.0.5 software package. TPC is not required since the maximum EIRP is less than 500 mW (27 dBm). The EUT utilizes the 802.11ac architecture. Three nominal channel bandwidths are implemented: 20 MHz, 40 MHz and 80 MHz. Therefore, pursuant to FCC KDB Publication 905462 D3, “Client devices with 80 MHz BW mode can be tested with an approved master operating in 40 MHz BW mode”. Therefore, 80MHz BW DFS testing was not performed and has been excluded from this report. The software installed in the access point is AP3G2-K9W7-M Version 15.2(4)JB4. The software installed in the EUT is Android revision 5.0.2; kernelversion 3.10.49. Page 14 of 32 UL VERIFICATION SERVICES INC.

OVERVIEW OF MASTER DEVICE WITH RESPECT TO §15.407 (h) REQUIREMENTS The Master Device is a Cisco Access Point, FCC ID: LDK102087. The minimum antenna gain for the Master Device is 6 dBi. The rated output power of the Master unit is > 23dBm (EIRP). Therefore the required interference threshold level is –64 dBm. After correction for procedural adjustments, 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 a margin to the limit. Page 15 of 32 UL VERIFICATION SERVICES INC.

MOVE AND CLOSING TIME REPORTING NOTES The reference marker is set at the end of last radar pulse. The delta marker is set at the end of the last WLAN transmission following the radar pulse. This delta is the channel move time. The aggregate channel closing transmission time is calculated as follows: Aggregate Transmission Time = (Number of analyzer bins showing transmission) * (dwell time per bin) The observation period over which the aggregate time is calculated begins at (Reference Marker + 200 msec) and ends no earlier than (Reference Marker + 10 sec).

MOVE AND CLOSING TIME REPORTING NOTES The reference marker is set at the end of last radar pulse. The delta marker is set at the end of the last WLAN transmission following the radar pulse. This delta is the channel move time. The aggregate channel closing transmission time is calculated as follows: Aggregate Transmission Time = (Number of analyzer bins showing transmission) * (dwell time per bin) The observation period over which the aggregate time is calculated begins at (Reference Marker + 200 msec) and ends no earlier than (Reference Marker + 10 sec). RESULTS Channel Move Time Limit (sec) (sec) 9.230 10 Aggregate Channel Closing Transmission Time Limit (msec) (msec) 6.0 60 Page 26 of 32 UL VERIFICATION SERVICES INC.
