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

Wireless USB Over UWB

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

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)
