5. doc.: IEEE 802.11-09/0583r0 Submission March 09, 2008 WilocitySlide 5 Usage Model 7: Cordless Computing Traffic Conditions: Multiple simultaneous high performance links, some with low latency requirements, others with simply best-effort rates. Use Case: 1. Notebook wirelessly connected to a docking station, or wirelessly connected to multiple wireless peripherals directly 2. Can be used in a dense office environment with multiple notebooks communicating to peripherals simultaneously. 3.Some data flows have significant latency requirements 4. Some data flows have significant QoS requirements (VoIP, Video streams, etc.) 5. Should enable multiple bus types to be transported over the wireless link Pre-Conditions: Cordless computing enables a wireless desktop experience, enabling a host notebook to connect to an array of peripherals, hard drives, printers, DVDs, ethernet, etc., wirelessly in a single home scenario as well as in a dense office environment Application: Cordless computing requires a solution that will eventually allow the wired IO connectors to disappear completely. These wired IO solutions are already or targeting multi-gigabit bit rates: USBIF is developing USB3 supporting 5Gbps, SATA supports over 2Gbps, and Gigabit Ethernet is also a > 1 gigabit per second IO. Devices in a cordless dock could include but are not limited to, storage (DAS/NAS), printers, scanners, DVD’s, Ethernet connection. A typical cordless dock may connect between 2 and 5 devices simultaneously in a remote or dense environment. Environment: Office scenario with density of approximately one unit per 9m 2 on average, and standalone home office usage. Range between notebook and dock will typically be < 3m NLOS. Shared devices can be up to 10m away from dock NLOS. Must be able to connect to various peripherals, monitor, file transfer and WLAN simultaneously. All devices will typically be fixed or stationary during usage.
