1.0 I N T R O D U C T I O N 1.1 Scope This report has been prepared to demonstrate compliance with the requirements for Dynamic Frequency Selection (DFS) as stated in KDB 905462 D02 V01R01. Testing was performed on the LG Portable Tablet FCC ID: ZNFUK495. As of July 20, 2007 all devices operating in the 5250 – 5350 MHz and/or the 5470 – 5725 MHz bands must comply with the DFS requirements. As the EUT does not have radar detection capability it was evaluated as a Client Only Device. All test results reported herein are applicable to the sample selected for testing. The unit used for testing was supplied by LG Electronics MobileComm U.S.A. 1.2 Evaluation Procedure Conducted test methodology was used for the DFS evaluation procedure of the LG Portable Tablet FCC ID: ZNFUK495. No deviations to the test procedure and test methods occurred during the evaluation of the EUT. 1.3 Summary of Test Results The LG Portable Tablet FCC ID: ZNFUK495 was found to be compliant with the requirements for DFS as required for a Client Device per Part 15.407(h) and KDB 905462 D02 V01R01.

3.0 D E S C R I P T I O N O F D Y N A M I C F R E Q U E N C Y S E L E C T I O N T E S T 3.1 Applicability The following table from KDB 905462 D02 V01R01 lists the applicable requirements for the DFS testing. The device evaluated in this report is considered a client device without radar detection capability. Requirement Operational Mode Client Without Client With Radar Master Radar Detection Detection Non-Occupancy Period Yes Not required Yes DFS Detection Threshold Yes Not required Yes Channel Availability Check Time Yes Not required Not required Uniform Spreading Yes Not required Not required U-NII Detection Bandwidth Yes Not required Yes Table 3-1. DFS Applicability Requirement Operational Mode Client Client Master Without Radar With Radar Detection Detection DFS Detection Threshold Yes Not required Yes Channel Closing Transmission Time Yes Yes Yes Channel Move Time Yes Yes Yes U-NII Detection Bandwidth Yes Not required Yes Client Beacon Test N/A Yes Yes Table 3-2. DFS Applicability During Normal Operation 3.2 Requirements Per KDB 905462 D02 V01R01 the following are the requirements for Client Devices: 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. FCC Pt. 15.407 DFS TEST REPORT Reviewed by: FCC ID: ZNFUK495 (CERTIFICATION) Quality Manager Test Report S/N: Test Dates: EUT Type: Page 6 of 15 0Y1503160586.ZNF 3/16 - 4/2/2015 Portable Tablet © 2015 PCTEST Engineering Laboratory, Inc. V 2.5 03/20/2015

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. Channel Move Time and Channel Closing Transmission Time requirements are listed in the following table. Parameter Value Non-occupancy period Minimum 30 minutes Channel Availability Check Time 60 seconds 10 seconds Channel Move Time See Note 1. Channel Closing Transmission Time 200 milliseconds + an aggregate of 60 milliseconds over remaining 10 second period. See Notes 1 and 2. Minimum 80% of the U- U-NII Detection Bandwidth NII 99% transmission power bandwidth. See Note 3. Note 1: The instant that the Channel Move Time and the Channel Closing Transmission Time begins is as follows: • For the Short Pulse Radar Test Signals this instant is the end of the Burst. • For the Frequency Hopping radar Test Signal, this instant is the end of the last radar Burst generated. • For the Long Pulse Radar Test Signal this instant is the end of the 12 second period defining the Radar Waveform. 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 1 is used and for each frequency step the minimum percentage of detection is 90 percent. Measurements are performed with no data traffic.

3.3 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. Table 3-4: Detection Thresholds for Master Devices and Client Devices with Radar Detection 3.4 Parameters of DFS Test Signals As the EUT is a Client Device with no Radar Detection only one type radar pulse is required for the testing. Radar Pulse type 1 was used in the evaluation of the Client device for the purpose of measuring the Channel Move Time and the Channel Closing Transmission Time. Table 3-5 lists the parameters for the Short Pulse Radar Waveforms. A plot of the Radar Pulse Type 1 used for testing is included in Section 5.0 of this report.

Parameters for Frequency Hopping Radar Waveforms 3.5 Procedure KDB 905462 D02 V01R01 describes a radiated test setup and a conducted test setup. The conducted test setup was used for this testing. Figure 3-1 shows the typical test setup. In Band 2A, one channel selected between 5260 and 5350 MHz is chosen for the testing. In Band 2C, one channel selected between 5500 and 5700 MHz was chosen for testing. Figure 3-1. Conducted Test Setup for DFS 1. The “Aeroflex PXI DFS Radar Simulator and Analyzer Test Suite” is setup to provide a simulated radar pulse at the frequency that the Master and Client are operating. A Type 1 radar pulse was used. 2. 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. 3. The MPEG file specified by the FCC (“6 ½ 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. 4. The “Aeroflex PXI DFS Radar Simulator and Analyzer Test Suite” is set to record and display 12 seconds of time, starting from where the simulated radar is generated. This time domain plot captures any transmissions occurring up to and after 10sec. Aggregate time is also computed per FCC 06-98 to ensure compliance. (Note: the channel may be different since the Master and Client have changed channels due to the detection of the initial radar pulse.) 5. After the initial radar burst the channel is monitored for 30 minutes to ensure no transmissions or beacons occur. A second monitoring setup is used to verify that the Master and Client have both moved to different channels.
