  2. July 2009 • doc.:IEEE 802.11-09/0838r0 Scenario 3 in TGac Evaluation Methodology • In-home entertainment application with multiple flows with varied QoS requirements including lightly-compressed video. • This scenario is derived from scenario #1 defined in 802.11n usage model document and modified in order to consider usage model 2a and 2b (PVR’s in residential) defined in ‘11-09-0161-02-00ac-802.11ac-usage-model-document’. Submission Slide 2 Minho Cheong, ETRI and Peter Loc, Ralink

  5. July 2009 • doc.:IEEE 802.11-09/0838r0 Service Description in Scenario 3 • STA1: Lightly-compressed video from AP • STA2: Display with HD MPEG2 quality, VoD control channel • STA3: Display with Blu-ray quality, VoD control channel • STA4: Display with Blu-ray quality, VoD control channel, Internet/local File transfer • STA5: Video Phone • STA6: Video Phone • STA7: PVR with HD MPEG2 quality • STA8: PVR with Blu-ray quality • STA9: PVR with Blu-ray quality • STA10: Internet streaming video, MP3 Audio, Video gaming, console to internet, local file transfer • STA11: Video gaming, controller to console • STA12: VoIP phone • STA13: VoIP phone • STA14: VoIP phone Submission Slide 5 Minho Cheong, ETRI and Peter Loc, Ralink

  6. July 2009 • doc.:IEEE 802.11-09/0838r0 About Devices with 1-2 Antennas • There is a proliferation of video/data traffic from small-form factor devices with 1-2 antennas. e.g., netbooks, smart-phones, camcorders, video-cams. • There is need to ensure that 11ac standards proposals scales network throughputs in the presence of such devices. • So, need to incorporate 1-2 antenna devices in simulation scenarios, to evaluate technology proposals. • In scenario 3, STA7, STA8 and STA9 may be PVR devices (such as handheld camcorders with 1-2 antennas). • In scenario 4, some devices involved in local file transfers may be netbooks or smartphones with 1-2 antennas. (e.g. STA11, STA12, STA 21, STA22) Submission Slide 6 Minho Cheong, ETRI and Peter Loc, Ralink

  7. Appendix - Usage Model 2a: Lightly Compressed Video Streaming throughout the home July 2009 • doc.:IEEE 802.11-09/0838r0 Pre-Conditions: User has operational WLAN network which includes a TV with wireless capabilities, a PVR with wireless capabilities, and an AP associated with the WLAN that is not in the same room as the game machine and TV. Application: User can display the output of the PVR wirelessly on the TV using a video codec like Motion 2000 JPEG that lightly compresses video. Environment: Two story, three bedroom house with an AP in one corner in the den. Other homes in the area are also operating WLANs. Transmissions are mostly Non-LOS. Distance between far corners of the home are ~100 feet with as many as 8 walls (and one floor) between the video end points. Traffic Conditions: • Occasional interference from other homes because WLAN is on other channels. Data transfers consuming up to 20% of the total bandwidth, 2 additional video streams, and wireless display/controllers from a video game machine may be occurring during this use case. Microwave may be running for up to 5 minutes. Use Case: • User looks up a program on electronic program guide. • User selects a video. • Lightly Compressed Video is delivered/uploaded over the wireless network for a period of two hours. • User may pause video during 2 hour period then resume watching. • Task is complete when user stops watching the video.

  8. Appendix - Usage Model 2b: Compressed video streaming in a room or throughout a home July 2009 • doc.:IEEE 802.11-09/0838r0 Pre-Conditions: User has operational WLAN network which includes a TV with wireless capabilities, a PVR with wireless capabilities, and an AP associated with the WLAN that is not in the same room as the game machine and TV. Application: User can display the output of the PVR wirelessly on the TV using high definition compressed video with a codec like BluRay . Expect three or four simultaneous HD streams. Environment: Two story, three bedroom house with an AP in one corner in the den. Other homes in the area are also operating WLANs. Transmissions are mostly Non-LOS. Distance between far corners of the home are ~100 feet with as many as 8 walls (and one floor) between the video end points. Traffic Conditions: • Severe interference from multiple streams in the house and other homes because WLAN is on other channels. High speed data transfers consuming up to 20% of the total bandwidth, many additional video streams, and wireless display/controllers from a video game machine may be occurring during this use case. Microwave may be running for up to 5 minutes. Use Case: • User looks up a program on electronic program guide. • User selects a video. • Compressed Video is delivered/uploaded over the wireless network for a period of two hours. • User may pause video during 2 hour period then resume watching. • Task is complete when user stops watching the video.
