What’s Happening in 2005 Around UWBWhat’s Happening in 2005 Around UWB
CY05Q1Merger of WiMedia and MBOA
FCC Grants Waiver for UWB MBOA Standard
CY05Q2Industry specs move towards 1.0 (MBOA, WUSB)
Prototype silicon available from few providers
Association customer study: secure yet effortless coupling
CY05Q3Compliance program development starts
Prototype drivers from Microsoft planned for WUSB
CY05Q4First products (probably low-volume) available to end customers
What’s Happening in 2006+ Around UWBWhat’s Happening in 2006+ Around UWB
CY06H1Prototypes for IP and WUSB on same siliconCompliance/Interop testing labs kick into gear
CY06H2High-volume UWB products around holiday season 2006Windows 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
IHVs Demonstrating Solutions at WinHECIHVs 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
Wireless USB – Technical OverviewWireless USB – Technical Overview
Similarities to wired USBHost – device topology
Up to 127 devices per host
Class driver protocol maintained
Keep complexity in host to make devices cheap
Bandwidth480 Mbps @ ~3M
110 Mbps @ ~10M
Scalable architecture (up to 1Gbps and beyond)
Power ManagementBattery preservation very important
PHY: 130-160mW for Tx/Rx
SecuritySECURE device association and authentication
Low encryption overhead, minimal perf impact
Ease of UseEasy install and setup
Backwards Compatibility with wired USB software
Low “device end” cost model

Small ‘key’ solutions
Device Wire AdapterDevice Wire Adapter
Looks like a wireless hub
Great for scenarios like wireless port replicators
Single chip implementations can be integrated directly into devices
USB2.0USB2.0
Cable protects datain-transit
Cable Ends define user’s connection choice
Association’s jobConnect the owner’s devices the way the owner wants them connected
Security’s jobMatch the security afforded by the USB wire
Protect data in-transit
Association and SecurityAssociation and Security
Secure AssociationSecure Association
Requires that both host and device have a common secret
Challenge is getting the secret to the deviceAssume 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)
Industry and Windows Compliance ProgramsIndustry and Windows Compliance Programs
Compliance programsIndustry – Being defined in WiMedia and USB-IF
Microsoft – Windows Logo Program
UWBFocus on certified silicon
The PAL used by the radio should be compliant with Microsoft supported PALs
AssociationThere'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 devicesWe may require all wired USB devices be tested downstream of a DWA
Isochronous devices (connected via WUSB) may need some software changes
TimelinesInitial Windows Logo Program Requirements coming shortly
Logo program validation tools to follow release of drivers
Industry Compliance PlansIndustry Compliance Plans
Applications own complianceDefine 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
TimelinesTest documents and tests developed 2H05
First compliance workshops in 1H06

IP Over UWB – SoftwareIP 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 – familiarityUPNP and Web Services for devices
IPv6
SummarySummary
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 comingDeveloper Conferences
Peripheral Development Kits
Interop Labs
Call to ActionCall to Action
IHVsShare 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
ParticipationAttend 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)
