Brief Review of 802.11ac Usage Models
• Category 2: Distribution of HDTV and other content
a. Lightly compressed video streaming around the entire home (100s of Mbps)
b. Compressed video streaming in a room or throughout a home
c. Intra-Large-Vehicle (e.g. airplane) Applications • Video streaming of 30-40 movies, 100s of TV channels to up to 300
people with individual play/rewind control over each stream
• Streams are ~5Mbps each. 300*5Mbps=1.5Gbps
d. Wireless Networking for Office
e. Remote Medical Assistance via Wireless Networks

Brief Review of 802.11ac Usage Models
• Category 3: Rapid Upload and Download of large files to/from servera. Rapid Sync-n-Go file transfer – camera to PC (10s of MB per pic), video kiosk
b. Picture-by-picture viewing - displaying digital pictures (jpegs, raw files) from a remote storage device to laptop or TV
c. Airplane docking – as airplane pulls up to the boarding gate:• plane down loads sensor (mechanic info, flight performance, maintenance) & flight information (e.g. crew, passenger info,
flight plan)
• plane uploads next flight information and new videos
d. Movie Content Download to Car as it pulls into garage
e. Police / Surveillance Car Upload• Upload several 10s of GB of data (Video Surveillance footage) from surveillance car to content server police station

• Category 6: Manufacturing Floor Automation– Factory floor within large metallic buildings. Applications have a
large variance in data transfer size, time sensitivity, and reliability.

Considerations for HEW Usage Model
• First, it is desirable to consider a simple evolution of already-defined 802.11ac 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

Considerations for HEW Usage Model
• Second, 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

Considerations for HEW Usage Model
• Third, it is desirable to consider new applications based on the specific Wi-Fi environments which HEW mainly tries to handle with– As time goes on, Wi-Fi AP’s and STA’s must be quite more
crowded with smaller distance each other, which may be most of cases obstacles to high data rate but for some cases, may be a chance for a new emerging market
– There will be potential applications which try to utilize quite denser deployment of AP’s and STA’s compared to 802.11ac days
– For example, geo-location service with the use of Wi-Fi for a Big mall (underground or on the ground) can quite better accuracy with the use of multiple neighboring AP’s which are closer each other

Crowded Residential Entertainment in an Apartment Building

Crowded Residential Entertainment in an Apartment Building
Pre-ConditionsApartment building has Wi-Fi network deployed to access internet and cloud services. AP is deployed in each house by single operator, but there are also some number of private AP’s.
Environment Apartment is a 20-story building. There are 10 houses per each floor. The size of each house in the apartment is 10m x 10m. AP is located at a random position of the each house. Per each house, there are 10 STAs connected to the AP, which includes set-top box of TV.
ApplicationsHome entertainment supporting video streaming for watching TV with HD resolution.
Video requirements are: ~20Mbps per STA, delay is < 200ms, 1.0E-3 PER.
Web browsing requirements for Social Networking are: ~10Mbps, delay<50ms.
200 active video users and 400 active web browsing users in the building (number of AP is 200).
Traffic ConditionsStrong interference from overlapping networks from 3 dimensional way (neighboring apartments, and outdoor Wi-Fi network). Multiple video display are operational simultaneously.
Use CaseUser starts cloud video service on a fixed or mobile device.

Super-dense STAs in City Square/Hot Spot
May 2013
Slide 13 Minho Cheong (ETRI)
• At an outdoor/indoor open area, huge number of pedestrians are attending a big event with smart phones at their hand for downloading streaming video on-line and uploading their own-taken/created video/picture at the very spot to YouTube (without any delay) to share with others.

Slide 14
Super-dense STAs in City Square/Hot SpotPre-ConditionsSuper density users access internet through multiple operators’ WLAN network.
Street or hot spot in the city possibly manages or controls multiple operators’ WLAN networks, but there are also many private AP’s there.
Environment The environment is very complex and may suffer severe interference.
There are 100,000 users in a 1km2 area. 400 AP’s are deployed in an non-uniform way which belong to multiple operator’s WLAN networks. The inter-AP distance is in the range of 25~75m. Single/multiple operators and some private AP’s.
ApplicationsFor each AP, video based applications: TV, VOD, HD compressed 50 users x 20 Mbps = 1 Gbps
Internet access: email, twitter, web surf, IM. 200 users x 10 Mbps, best effort = 2 Gbps
Traffic ConditionsPotential interference from overlapping networks (e.g. neighbors, other WLANs, private AP’s). Data transfers and video display should be operating concurrently.
Use CaseHuge number of pedestrians are using the network to surf websites, watch movies, play games and access cloud services and upload their own created contents to YouTube to share with others without any delay.

Intra-Small-Vehicle for Commuting Time
May 2013
Slide 15 Minho Cheong (ETRI)
• Different than air-plane or train which is defined before as “Intra-Large-Vehicle”, Subway cabin or Bus cabin is likely to experience quite severer interferences due to huge number of STAs in a very limited area. In addition, most of users may be slowly moving.

Intra-Small-Vehicle for Commuting TimePre-Conditions: High density users have operational WLAN network for Internet access during very crowded time such as commuting time. User can access the onboard entertainment system (internal) and Internet (external).
Environment: Indoor open area with many obstacles most of which are human body blockings. Each cabin has separate WLAN connectivity for subway cabin. For bus, there is a single cabin. People can be slowly moving in the cabin.
Application: Onboard entertainment: Broadcast and local VoD services, Internet Access, Gaming, public safety: Local VoD services, monitoring: 50 x 20 Mbps = 1.0 G
25 users listening to HD audio
25 users doing interactive gaming ; 25 x 20 Mbps = 0.5 Gbps, <100 ms jitter and <100 ms latency
Traffic ConditionsPotential interference from overlapping networks (e.g. neighbors, other WLANs). Data transfers and video display should be operating concurrently.
Use Case100 passengers in one cabin (10 m x 3m).
Passengers access via WLAN the onboard the entertainment system for video display, audio, and interactive gaming activities.
Passengers also access the Internet via the WLAN.

Smart Phone’s Wi-Fi LBS
• Dense deployment of AP’s in a limited indoor area is beneficial to the indoor LBS (Location-based service) on the contrary, because the closer AP’s deployed each other, the more accurate resolution it can support.
