  1. UWB:A High-Speed Wireless PAN Technology Brad Hosler Wireless USB Architect brad.w.hosler @ intel.com Intel Corporation Fred Bhesania Program Managerfredbh @ microsoft.com Microsoft Corporation

  2. Session Outline • Industry activities around UWB • Microsoft’s participation and vision • Overview of supported protocols on UWB • Wireless USB over UWB • IP over UWB • Summary • Call to action for partners

  3. UWB Overview FCC ruling permits UWB spectrum overlay • UWB is presently legal only in the US • Regulatory activity underway in Europe, Japan, and China • Consistency “rules of the game” • Open standardization is critical for worldwide market adoption

  4. UWB Overview (con’t) UWB Throughput • High speed at short range • 480 Mb/s at ~3m • Does not penetrate walls • Scaleable performance (Moore’s Law radio)

  5. UWB in the Digital Home Local high throughput delivery Wired /Wireless Wired / Wireless Broadband Wired / Wireless Long range delivery wired & wireless (Backbone) Wired / Wireless Wired / Wireless UWB defines high spatial capacity and effortless interconnectivity

  6. UWB Initiative Ecosystem 180+ companies (PC, CE, Cellular Players) Convergence layer for multiple protocols WiMedia Endorses MBOA PHY May 04 UWB PHY and MAC standardization Endorsed MBOA PHY, MAC Feb 04 WUSB Protocol

  7. UWB Protocol Relationships Legend High customer interest Low customer interest Other Applications Wireless 1394 Items with ‘*’ are being defined in WiMedia Convergence Layer* Wireless USB IP (WiNet*) MBOA UWB MAC* MBOA UWB PHY* Various technology solutionsrunning over the common platform Common Ultrawide Band Radio Platform

  8. Industry Group Structure Non-IP Peer-to-peer (W1394) Peripheral Interconnect (WUSB) WiNet USB-IF IP Networking Convergence Layer MBOA UWB MAC WiMedia MBOA UWBPhy

  9. What’s Happening in 2005 Around UWB • CY05Q1 • Merger of WiMedia and MBOA • FCC Grants Waiver for UWB MBOA Standard • CY05Q2 • Industry specs move towards 1.0 (MBOA, WUSB) • Prototype silicon available from few providers • Association customer study: secure yet effortless coupling • CY05Q3 • Compliance program development starts • Prototype drivers from Microsoft planned for WUSB • CY05Q4 • First products (probably low-volume) available to end customers

  10. What’s Happening in 2006+ Around UWB • CY06H1 • Prototypes for IP and WUSB on same silicon • Compliance/Interop testing labs kick into gear • CY06H2 • High-volume UWB products around holiday season 2006 • Windows codenamed “Longhorn” planned for customers • Throughout this period, plenty of opportunity to: • Attend industry training events (e.g. Wireless USB Developers Conference in US and Asia) • Participate in prototype testing before (un)plugfests commence

  11. IHVs Demonstrating Solutions at WinHEC • Some of the companies developing Wireless USB silicon and participating at WinHEC… • Showing off initial prototypes and design-wins • Participating in industry specification development To get more details, please visit these companies it the Wireless USB Community an the exhibition

  12. Wireless USB Over UWB

  13. Wireless USB – Technical Overview Similarities to wired USB Host – device topology Up to 127 devices per host Class driver protocol maintained Keep complexity in host to make devices cheap Bandwidth 480 Mbps @ ~3M 110 Mbps @ ~10M Scalable architecture (up to 1Gbps and beyond) Power Management Battery preservation very important PHY: 130-160mW for Tx/Rx Security SECURE device association and authentication Low encryption overhead, minimal perf impact Ease of Use Easy install and setup Backwards Compatibility with wired USB software Low “device end” cost model

  14. Communication Topology Logical Data Communications Topology

  15. Host Radio Solutions • PCI (or PCIe) -based solution • Can go in add-in card slot • Cardbus or ExpressCard solutions • Wired USB dongle • Cabled ‘base station’ variety • Small ‘key’ solutions

  16. Device Wire Adapter USB2.0 • Looks like a wireless hub • Great for scenarios like wireless port replicators • Single chip implementations can be integrated directly into devices

  17. Association and Security • Association’s job • Connect the owner’s devices the way the owner wants them connected • Security’s job • Match the security afforded by the USB wire • Protect data in-transit Cable Ends define user’s connection choice Cable protects datain-transit

  18. Secure Association • Requires that both host and device have a common secret • Challenge is getting the secret to the device • Assume that host generates the secret • Three mechanisms are being considered: • Use a cable • Use UWB radios with PK technology and user authorization • Use Near Field Communication (NFC)

  19. Industry and Windows Compliance Programs • Compliance programs • Industry – Being defined in WiMedia 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 impact 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

  20. Industry Compliance Plans • Applications own compliance • Define requirements/assertions • Run workshops • Allow logo usage • WiMedia provides turn-key compliance solution for PHY, MAC, and radio cooperation • Application compliance will incorporate WiMedia tests for logo requirements • Timelines • Test documents and tests developed 2H05 • First compliance workshops in 1H06 WUSB IP Cooperation policy WiMedia UWB MAC WiMedia UWBPhy

  21. IP Over UWB

  22. IP Over UWB – Vision • High Speed Peer Networking • Ad-hoc (Proximity Meeting Scenarios) • File Sharing • IP Connected Devices • Synchronization • A / V Streaming • Printing • Ethernet cable replacement (office hub) • Primary focus • Focus on ease of use • High security

  23. IP Over UWB – Software • Early availability of IP over UWB provides familiar communication plane • Avoids proliferation of profiles & protocols (as with Bluetooth) • Enabler for Mesh Networking • Builds on Native 802.11 and Media Extensibility architecture • Same user experience for different wireless technologies • Uses same higher level protocols – familiarity • UPNP and Web Services for devices • IPv6

  24. Summary • Industry specs are nearly complete and prototype hardware will be available soon • Microsoft committed to providing beta drivers to early IHVs for validation purposes • Training and tools are coming • Developer Conferences • Peripheral Development Kits • Interop Labs

  25. 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/self-hosting • Participation • Attend Wireless USB Developers Conference onMay 24-25 in San Jose, to learn more on WUSB • Participate with Microsoft on beta opportunities. • Test wired USB devices on • DWA + WHCI/HWA Scenarios • All platform architecture (x86, x64, Itanium)
