Ultra Wide Band UWB Architecture Preview Outline Microsofts

Ultra. Wide 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 FCC ruling permits UWB spectrum overlay UWB Throughput • 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 • High speed at short range • 480 Mb/s at ~3 m • Does not penetrate walls • Scaleable performance (Moore’s Law radio)

UWB in the Digital Home Local high throughput delivery Wired / Wireless 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. No new kernel/user APIs for UWB plan to be exposed

Association – HARD Scenarios Association Is One Of The Key Elements To UWB’s Success Hard Scenario #1 – HID Keyboard/Mouse/Human Input Device Hard Scenario #2 – Far apart Device and host are not physically close enough to use a cable Device and host are heavy and not convenient to move them Hard Scenario #3 – Headless hosts How to associate a device with a headless server (no monitor for showing the PIN/user entry, etc. ) Hard Scenario #4 – OEM Install Pre-associating devices at OEM (during OS setup/upgrade). Hard Scenario #5 – OS + BIOS / Multiple OS. Associating a device with a host in such a way that the device is also associated with the same PC/radio in BIOS mode. Solve the hard problems and the rest are no-brainers!!

Windows Connect Now And the solution is …… The Windows Networking and Device Connectivity Platform Effortless “It Just Works” experience for users Simple protocols, APIs and DLLs for partners and developers Secure and Reliable Built-in security to enable higher user confidence Make reliability a fundamental part of the solution State of the art Continue enabling compelling new user experiences

Wireless Host Side Architecture UWB radio supported on these buses: PCI (or PCIe) based solution Can go in addin card slot Cardbus or Express. Card possible Wired USB dongle Cabled ‘base station’ variety Small ‘key’ solutions Microsoft preferred PALs required on UWB host side radio WUSB IP

Role of Convergence / Management Layer Bandwidth management and arbitration Between PALs Inform other hosts to optimize bandwidth Changing channels if congestion Handling PCI resources Function or PAL enumeration Beaconing and Topology management

Device Wire Adapter Looks like a wireless hub Great for scenarios like wireless port replicators Single chip implementations can be integrated directly into devices USB 2. 0

Industry and Windows Compliance Programs Compliance programs Industry – Being defined in Wi. Media and USB-IF Microsoft – Windows Logo Program UWB Focus on certified silicon The PAL used by the radio should be compliant with Microsoft supported PALs. Association There's a lot of work/innovation going on in this space still Use Microsoft supported association models – Windows Connect Now Wireless USB is likely to affect wired USB devices We may require all wired USB devices be tested downstream of a DWA Isochronous devices (connected via WUSB) may need some software changes Timelines Initial Windows Logo Program requirements coming shortly Logo program validation tools to follow release of drivers

Windows Logo Program Requirements Host side radios Must be compliant with either WHCI or HWA specifications (and related specifications) Must support isoch transfers Device wire adapters DWA's with exposed ports need to provide 500 ma on all ports Must support isoch transfers Possible requirements around number of RPipes Devices WUSB devices must have a unique serial number Devices must be compatible with both HWA and WHCI hosts No plans to logo non-beaconing devices

Industry Compliance Plans Define requirements/assertions Run workshops Allow logo usage Wi. Media provides turn-key compliance solution for PHY, MAC, and radio cooperation Application compliance will incorporate Wi. Media tests for logo requirements Timelines Test documents and tests developed 2 H 05 First compliance workshops in 1 H 06 WUSB Applications own compliance testing IP Cooperation policy Wi. Media UWB MAC Wi. Media UWB Phy

Summary Industry specs are nearly done and prototype hardware is available to IHVs Microsoft committed to providing beta drivers to early IHVs for validation purposes Training and tools are coming Developer Conferences Peripheral Development Kits Interop Labs

Call to Action IHVs Share UWB plans with Microsoft and come up with a great Go. To-Market Strategy Send sample devices to Windows UWB team for testing/selfhosting Participation Attend Wireless USB Developers Conference on May 24 -25 in San Jose, to learn more on WUSB Participate with Microsoft on beta opportunities. Send us your feedback Test wired USB devices on DWA + WHCI/HWA Scenarios All platform architecture (x 86, x 64, Itanium)
