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 ~3M
110 ~10M
Scalable architecture (up to 1Gbps and beyond)
Power Management
Battery preservation very important
PHY: mW 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. PCI (or PCIe) -based solution
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. Looks like a wireless hub
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

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

18. Requires that both host and device have a common secret
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
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 IP
WUSB
Cooperation policy
WiMedia UWB MAC
WiMedia UWB Phy

21. IP Over UWB

22. High Speed Peer Networking
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. Builds on Native 802.11 and Media Extensibility architecture
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 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. Training and tools are coming
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. Test wired USB devices on
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
