8 doc.: IEEE 802.11-13/0795r0 Submission Usage Model: Dense use of wireless docking in large office enterprise Pre-Conditions: User has operational WLAN network for Internet access and general data networking. The wireless network used for storage and display may or may not be part of the other operational WLAN network. Application: User can wirelessly display the output of the computer to monitor. User can wirelessly store data from a computer to a harddrive. Environment: Devices are operating in close proximity to other similar clusters in a multi-cube office. Transmissions are mostly LOS. Traffic Conditions: Potential interference from overlapping networks (e.g. neighbors, other WLANs). Data transfers and video display should be operational simultaneously. Use Case: 1.User sits down to their desk, turns on their computer. 2.Computer wirelessly forms an association to an external hard drive and the display with minimal user configuration. 3. User works for extended hours without a visible sign that the display is using wireless technology. 4. User stops working, then turns off computer. July 2013 Eldad Perahia (Intel)Slide 8
