Mobile video drives mobile data traffic Month Year doc.: IEEE 802.11-yy/xxxxr0 May 2013 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** * https://support.netflix.com/en/node/8731 ** 4 out of 10 top selling TVs on Amazon.com April 22, 2013 Klaus Doppler, Nokia John Doe, Some Company

Dense apartment building May 2013 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 May 2013 Indoor environment Month Year doc.: IEEE 802.11-yy/xxxxr0 May 2013 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 channel @ 5GHz Klaus Doppler, Nokia John Doe, Some Company

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

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 Klaus Doppler, Nokia

May 2013 Input for the 5 criteria HEW shall achieve 2-3 times the average BSS throughput compared to 802.11ac 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 802.11ac in a multi-floor building with a dense deployment of Wi-Fi networks Klaus Doppler, Nokia
