Slide 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
Slide 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 Emitted Signal Power GPS Bluetooth, 802.11b WLAN Cordless Phones Microwave Ovens PCS 802.11a WLAN Cordless Phones ISM band U-NII band -41 dBm/Mhz 1.6 1.9 2.4 3.1 “FCC Part 15 Limit” UWB Spectrum 5 10.6 Note: not to scale Frequency (Ghz)
Slide 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)
Slide 5: UWB in the Digital Home Local high throughput delivery Wired /Wireless Broadband Wired / Wireless Wired / Wireless Long range delivery wired & wireless (Backbone) Wired / Wireless Wired / Wireless UWB defines high spatial capacity and effortless interconnectivity
Slide 6: UWB Initiative Ecosystem Convergence layer for multiple protocols 180+ companies (PC, CE, Cellular Players) WiMedia Endorses MBOA PHY May 04 UWB PHY and MAC standardization WUSB Protocol Endorsed MBOA PHY, MAC Feb 04
Slide 7: UWB Protocol Relationships Other Applications Wireless USB Legend Wireless 1394 High customer interest Low customer interest Items with ‘*’ are being defined in WiMedia Various technology solutions running over the common platform Convergence Layer* Common Ultrawide Band Radio Platform MBOA UWB MAC* MBOA UWB PHY* IP (WiNet*)
Slide 8: Industry Group Structure IP Networking WiNet Peri pheral Inte rconnect (WUSB) Non-IP Peer-to-pee r (W1394) USB-IF Convergence Layer MBOA UWB MAC MBOA UWB Phy WiMedia
Slide 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
Slide 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
Slide 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
Slide 12: Wireless USB Over UWB
Slide 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 Power Management Battery preservation very important PHY: 130-160mW for Tx/Rx Security SECURE device association and authentication Low encryption overhead, minimal perf impact Bandwidth 480 Mbps @ ~3M 110 Mbps @ ~10M Scalable architecture (up to 1Gbps and beyond) Ease of Use Easy install and setup Backwards Compatibility with wired USB software Low “device end” cost model
Slide 14: Communication Topology Wireless USB Host Wireless USB Device Delta Change (from USB 2.0) Client SW Function Very Small Change (Isochronous Only ) Function Layer USB System SW WUSB Logical Device Device Layer Small Change (Security Framework ) WUSB Host Controller WUSB “BUS” Interface “BUS” Interface Layer Very Large Change Actual Communications Flow Logical Communications Flow Transmissions Encrypted Secure Relationship Logical Data Communications Topology
Slide 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
Slide 16: Device Wire Adapter Looks like a wireless hub Great for scenarios like wireless port replicators Single chip implementations can be integrated directly into devices USB2.0
Slide 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 data in-transit
Slide 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)
Slide 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
Slide 20: Industry Compliance Plans Applications own compliance WUSB WUSB Define requirements/assertions Run workshops Allow logo usage IP 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 Cooperation policy WiMedia UWB MAC WiMedia UWB Phy
Slide 21: IP Over UWB
Slide 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
Slide 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
Slide 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
Slide 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 on May 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)
