doc. : IEEE 11 -13/0836 r 0 May 2013 Values of HEW Usage Models [1] • 1 st value: it is desirable to consider a simple evolution of already-defined 802. 11 ac usage models – Possibly, by supporting higher data rate for the existing models – By supporting more number of AP’s and STA’s for the deployment of existing models • Category 1: Wireless Display – transfer content between devices – Many houses in an apartment use in-room gaming or video-streaming • Category 2: Distribution of HDTV and other content – Wireless Office, Remote Surgery, Intra-large vehicle application • Category 3: Rapid Upload and Download of large files to/from server – Sync. & go among lots of devices in a limited area • Category 4: Backhaul – mesh type or point-to-point backhaul supporting ultra high data rate • Category 5: Outdoor Campus / Auditorium deployments – Campus lecture halls supporting tele-presence of ultra high data rate • Category 6: Manufacturing Floor Automation Submission Slide 3 Minho Cheong (ETRI)

doc. : IEEE 11 -13/0836 r 0 May 2013 Values of HEW Usage Models [1] • 2 nd value: it is desirable to define new usage models reflecting new cultural landscapes emerged during last several years – Nowadays, people are more likely to volunteer to participate an event to have a common experience in the open area – People are more likely to enhance their experience a lot by downloading streaming video even at the very spot and share their experience with others by uploading video/picture without any delay at the spot as well. – Cloud computing with the use of Wi-Fi is very popularized now • 3 rd value: it is better to also consider new additional applications which rather aggressively try to utilize the current Wi-Fi problems which HEW mainly tries to handle with – Such as Wi-Fi geo-location services for dense AP deployments Submission Slide 4 Minho Cheong (ETRI)

Mesh Portal AP 1 st Hop 2 nd Hop AP AP 3 rd Hop AP AP Applications are evolving towards more high-quality video intensive use cases for monitoring as well as reporting and interaction. The mesh backhaul, will carry very high traffic loads. HEW Link Non-HEW link Submission Slide 9 Minho Cheong (ETRI)

doc. : IEEE 11 -13/0836 r 0 July 2013 Usage Model 1 f: Multi-Media Mesh Backhaul Pre-Conditions: Mesh topology with one Mesh Portal AP with wired link to a network such as the Internet. An example topology could be up to 3 hops from Mesh Portal AP and 1~10 clients per AP. APs provide mesh routing with simultaneous access for clients. Mesh Portal AP also provide connectivity for clients. Application: Traffic is both outbound and inbound for data, high-quality video and voice. Data may include scheduled hard-drive backups of many PCs. Video is high definition compressed video using, for example, a VHD high compressed video (100 Mbps) or HD video (20 Mbps). High definition voice may be using a codec like GIPS i. PMC-wb or G 729. 1. Environment: Mesh backhaul for hot spot, enterprise, small office/home office, campus, and municipal deployments. Line of Sight as well as NLOS. There is some unmanageable interference in the area. Hops with a 50 to 200 m separation from each other. Submission Traffic Conditions: Mesh Portal AP VHT interface reaches capacity limits with an equal amount of inbound and outbound traffic. Packets may be aggregated. Use Case: 1. User on client devices looks up a program on electronic program guide. 2. User selects a video. 3. High Quality Compressed Video is delivered/uploaded over the wireless network for a period of two hours. 4. User may pause video during 2 hour period then resume watching. 5. Upload/downloading a file while watching the movie is a background task that is not likely to be interrupted. 6. Task is complete when user stops watching the video. 7. The video from multiple clients is aggregated up through the mesh network through the Mesh Portal AP. Slide 10 Minho Cheong (ETRI)

July 2013 doc. : IEEE 11 -13/0836 r 0 Usage Model 2 d: Manufacturing Floor Automation Pre-Conditions: Multiple WLAN networks are operational in manufacturing space that has hundreds to thousands of individual tasks happening each minute. Many of these tasks require communications. Application: All types of information required to run large manufacturing floor. Large variances in data transfer size, time sensitivity, and reliability exist. Here are some examples: • Streaming of live or CAD video requires high throughput, time sensitive, and reliable transfers: VHD compressed video (100 Mbps, <20 ms jitter/delay, <1. 0 E-7 PER) or HD compressed video (20 Mbps, <50 ms jitter/delay, <1. 0 E-5 PER) or SD compressed video (5 Mbps, <200 ms jitter/delay, <1. 0 E-4 PER) • Voice requires lower bandwidth and time sensitive transfers; reliability is less of a concern: standard quality voice streams (<50 Kbps, <10 ms jitter/delay, <1. 0 E-2 PER). 30 calls yields aggregate bandwidth requirement of 1. 5 Mbps. • Machine-machine communications, robotic material handling requires high reliability but is less time sensitive. • Data loading machines is high bandwidth but low in time sensitivity. Application layer protocols would ensure reliability. Environment: Communications are within a large metallic building with 100 m x 100 m for 1000 devices. 4 WLAN AP’s are separated each other by equal distance of 50 in the building. High reverberation, long propagation distances (10’s~100’s meters), long delay spreads. Constantly moving equipment changing RF propagation channel model. Submission Slide 11 Traffic Conditions: 1000 independent links and data streams with varying Qo. S, reliability, and throughput, requirements. Aggregate data flows range into multiple Gbps requirements for each BSS. Use Case: 1. Multiple systems in factory; starting, stopping, and flowing network traffic in a largely asynchronous environment with the use of multiple WLAN BSS’s. 2. Some data flows have significant integrity requirements (large material-handling machines; cranes, crawlers, etc. ) 3. Some data flows have significant Qo. S requirements (Vo. IP, Video streams, etc. ) 4. Factory is VERY electrically noisy; spark-gap noise (electric motors, etc. ), microwave ovens, other technologies (RFID, RTLS, etc. ), and competing 802. x wireless systems such as 802. 15. 4 g Zig.

doc. : IEEE 11 -13/0836 r 0 July 2013 Usage Model 5 d: Point-to-Point Backhaul HEW Link Submission Slide 12 Minho Cheong (ETRI)

doc. : IEEE 11 -13/0836 r 0 July 2013 Usage Model 5 d: Point-to-Point Backhaul Pre-Conditions: Networks (wired or wireless) are be connected via a point-to-point link. The individual networks can support hundreds of users with a wide array of traffic requirements that will only be limited by the HEW link capabilities. Environment: Point-to-point link distance is 50 meters to 200 meters. Typically locations are Line of Sight. There is some unmanageable interference around the area. Application: Traffic is bidirectional and is comprised of data, voice, high-quality video and data. Data may include scheduled hard-drive backups of many PCs. High Definition Video is compressed using something like a VHD high compressed video (100 Mbps) or HD video (20 Mbps). High definition voice may be using a codec like GIPS i. PMC-wb or G 729. 1. Each building may hundreds of end users. Consider the case of up to 50 users requiring multi-media connectivity through the point-to-point link at any given moment in time. (50% for VHD, 50% for HD) Aggregate of 50 users = (20 M*25 users + 100 M*25 users) = 3. 0 Gbps throughput. Traffic Conditions: Point-to-point link can carry traffic with multiple Qo. S categories. End of each link is heavily loaded with equal amount of traffic in both directions. Use Case: 1. Two builds are on opposite sides of a rail road track. The building owner has no rights to lay a wire in the ground between buildings. 2. Owner sets up a wireless HEW link between the buildings. 3. Users can now take advantage multi-media applications spanning both buildings. Submission Slide 13 Minho Cheong (ETRI)
