Bay Area Compliance Laboratories Corp.(Taiwan) No.: RLK1810002-00C Setup for Client with injection at the Client 5.4 Test Procedure A spectrum analyzer is used as a monitor verifies that the EUT status including Channel Closing Transmission Time and Channel Move Time, and does not transmit on a Channel during the Non-Occupancy Period after the diction and Channel move. It is also used to monitor EUT transmissions during the Channel Availability Check Time. Note: This test report is prepared for the customer shown above and for the device described herein.

Bay Area Compliance Laboratories Corp.(Taiwan) No.: RLK1810002-00C 6 TEST RESULT 6.1 Description of EUT The EUT operates in 5250-5350 MHz and 5470-5725 MHz range. The rated output power of master device is >23 dBm (EIRP), therefore the required interference threshold level is -64 dBm, the required radiated threshold at antenna port is -64dBm. 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. The calibrated radiated DFS detection threshold level is set to -64+1+(Master antenna gain:) = Band 2 : -64+1.11+1= -61.89 dBm. Band 3 : -64+1.61+1= -61.39 dBm 6.2 Channel Loading System testing will be performed with channel-loading using means appropriate to the data types that are used by the unlicensed device. The following requirements apply: a) The data file must be of a type that is typical for the device (i.e., MPEG-2, MPEG-4, WAV, MP3, MP4, AVI, etc.) and must generally be transmitting in a streaming mode. b) Software to ping the client is permitted to simulate data transfer but must have random ping intervals. c) Timing plots are required with calculations demonstrating a minimum channel loading of approximately 17% or greater. For example, channel loading can be estimated by setting the spectrum analyzer for zero span and approximate the Time On/ (Time On + Off Time). This can be done with any appropriate channel BW and modulation type. d) Unicast or Multicast protocols are preferable but other protocols may be used. The appropriate protocol used must be described in the test procedures. The sample is use method (C) WLAN traffic is generated by streaming the video file TestFile.mpg, this file is used by IP and Frame based systems for loading the test channel during the In-service compliance testing of the U-NII device. The file is streamed from the Access Point to the Client in full motion video mode using the media player with the V2.61 Codec package.
