May 2013 Doc. No. IEEE 11 -13 -0538 -00 -0 hew-r 0 Dense apartment

May 2013 Doc. No. IEEE 11 -13 -0538 -00 -0 hew-r 0 Dense apartment building 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 Web browsing requirements for Social Networking are: ~20 Mbps, PER 1 e-3, delay<50 ms, 1. 0 E-3 PER 150 active video users and 100 active web browsing users in the building with an aggregate data rate requirement of 18. 8 Gbps in the building. The service requirements should be met for 98% of the users in the building. Environment Traffic Conditions Building with 100 apartments. One AP in each apartment of 10 mx 10 m randomly positioned. 5 STA per AP randomly positioned in the apartment. Strong interference from overlapping networks (neighboring apartments, and outdoor Wi-Fi network). Multiple video display are operational simultaneously. Applications Use Case Cloud based applications supporting video streaming with 8 k resolution. Video requirements are: ~112 Mbps per STA (16 x 1080 P), delay is < 200 ms, 1. 0 E-3 PER. The application is able to buffer up to 2 s of the content to avoid interruptions of the service, allowing relaxed delay requirements User starts cloud video service on a fixed or mobile device with 8 k display. Pre-Conditions Submission The cloud service streams the video in 8 k format. Slide 4 Klaus Doppler, Nokia
