Mobile video drives mobile data traffic
Video is dominant application
Netflix in HD currently uses 7Mbps*
Video is moving towards 4k (4x1080p) and 8k (16x1080p)
Increasing share of TVs with Wi-Fi support** *
** 4 out of 10 top selling TVs on Amazon.com April 22, 2013

4. Dense apartment building

Dense apartment building
Pre-Conditions
Each apartment has Wi-Fi network deployed to access internet and cloud services. In each apartment up to 3 users stream concurrently video content from the network and up to 50% of the networks are active.
At the same time each of the active Wi-Fi networks is used by 2 users for web browsing
Environment
Building with 100 apartments. One AP in each apartment of 10mx10m randomly positioned. 5 STA per AP randomly positioned in the apartment.
Applications
Cloud based applications supporting video streaming with 8k resolution.
Video requirements are: ~112Mbps per STA (16x1080P), delay is < 200ms, 1.0E-3 PER.
The application is able to buffer up to 2s of the content to avoid interruptions of the service, allowing relaxed delay requirements
Web browsing requirements for Social Networking are: ~20Mbps, PER 1e-3, delay<50ms, 1.0E-3 PER
150 active video users and 100 active web browsing users in the building with an aggregate data rate requirement of 18.8Gbps in the building.
The service requirements should be met for 98% of the users in the building.
Traffic Conditions
Strong interference from overlapping networks (neighboring apartments, and outdoor Wi-Fi network). Multiple video display are operational simultaneously.
Use Case
User starts cloud video service on a fixed or mobile device with 8k display.
The cloud service streams the video in 8k format.

Scenario
Indoor environment
Multi-floor building (100 apartments)
5 floors
2x10 rooms in each floor
Room size:10m x 10m x 3m
1-100 AP in the middle of the room
2 STA/AP
Randomly placed in the same room as AP
Constant Bit Rate traffic both DL and UL
10Mbps/10Mbps
AP TxP 23dBm, STA TxP 16dBm
One 20MHz 5GHz

6. Evaluation criteria Average user throughput
May 2013
Evaluation criteria
Average user throughput
Averaged over all STA in building
5 Percentile of User Throughput Cumulative Distribution Function
95% of STA in building have a higher throughput
Klaus Doppler, Nokia

7. Results 10Mpbs/10Mbps Average User Throughput (Mbps)
5 percentile of user throughput CDF
20Mbps
20Mbps
Throughput drops fast if #active BSS higher than 10
Lowest 5% of users get less than 1Mbps if #active BSS higher than 17

8. Proposed criteria for distinct identity
May 2013
Proposed criteria for distinct identity
HEW shall achieve 2-3 times the average BSS throughput compared to ac in a multi-floor building with dense deployment of Wi-Fi networks
HEW shall increase 4-10 times the 5 percentile of the user throughput Cumulative Distribution Function compared to ac in a multi-floor building with a dense deployment of Wi-Fi networks
