UltraWide Band (UWB) Architecture Preview Outline Microsoft’s Participation and Vision Supported Protocols currently planned for UWB Wireless USB IP Synergy between IHVs/ISVs and UWB Team Call to action for partners Summary UWB Overview UWB is presently approved for use only in the US Regulatory activity underway in Europe, and Asia Consistency “rules of the game” Open standardization is critical for worldwide market adoption FCC ruling permits UWB spectrum overlay UWB Throughput High speed at short range 480 Mb/s at ~3m Does not rate walls Scaleable performance (Moore’s Law radio) UWB in the Digital Home Wired / Wireless Wired / Wireless Wired /Wireless Wired / Wireless Local high throughput delivery Long range delivery wired & wireless (backbone) Wired / Wireless UWB delivers high speed interconnectivity at low power/proximity UWB Project in Windows Description Create infrastructure to build on Microsoft’s huge investment in USB and IP class drivers over a new medium/transport Project Goals Reuse existing class drivers unchanged (except USB ISOCH) Minimal changes to existing USB and IP core stack Simple association model High security (make it just as secure as cable scenarios) Allow IHVs to write a single function driver on top of the appropriate PALs for wired and wireless scenarios Class drivers should be developed on top of PALs.
