Summary

UWB Overview UWB Overview

• UWB is presently approved for use only in the US

• Regulatory activity underway in Europe, and Asia

• Consistency “rules of the game”

• Open standardization is critical for worldwide market adoption

UWB Project in WindowsUWB Project in Windows

DescriptionCreate infrastructure to build on Microsoft’s huge investment in USB and IP class drivers over a new medium/transport

Project GoalsReuse existing class drivers unchanged (except USB ISOCH)

Minimal changes to existing USB and IP core stack

Simple association model

High security (make it just as secure as cable scenarios)

Allow IHVs to write a single function driver on top of the appropriate PALs for wired and wireless scenarios

Class drivers should be developed on top of PALs. No new kernel/user APIs for UWB plan to be exposed

Association – HARD ScenariosAssociation – HARD Scenarios

Association Is One Of The Key Elements To UWB’s SuccessHard Scenario #1 – HID

Keyboard/Mouse/Human Input Device

Hard Scenario #2 – Far apartDevice and host are not physically close enough to use a cable

Device and host are heavy and not convenient to move them

Hard Scenario #3 – Headless hostsHow to associate a device with a headless server (no monitor for showing the PIN/user entry, etc.)

Hard Scenario #4 – OEM InstallPre-associating devices at OEM (during OS setup/upgrade).

Hard Scenario #5 – OS + BIOS / Multiple OS.Associating a device with a host in such a way that the device is also associated with the same PC/radio in BIOS mode.

Solve the hard problems and the rest are no-brainers!!

Windows Connect NowWindows Connect Now

And the solution is ……

The Windows Networking and Device Connectivity Platform

Effortless“It Just Works” experience for users

Simple protocols, APIs and DLLs for partners and developers

Secure and ReliableBuilt-in security to enable higher user confidence

Make reliability a fundamental part of the solution

State of the artContinue enabling compelling new user experiences

Wireless Host Side ArchitectureWireless Host Side Architecture

UWB radio supported on these buses:

Industry and Windows Compliance ProgramsIndustry and Windows Compliance Programs

Compliance programsIndustry – Being defined in WiMedia and USB-IFMicrosoft – Windows Logo Program

UWBFocus on certified siliconThe PAL used by the radio should be compliant with Microsoft supported PALs.

AssociationThere's a lot of work/innovation going on in this space stillUse Microsoft supported association models – Windows Connect Now

Wireless USB is likely to affect wired USB devicesWe may require all wired USB devices be tested downstream of a DWAIsochronous devices (connected via WUSB) may need some software changes

TimelinesInitial Windows Logo Program requirements coming shortlyLogo program validation tools to follow release of drivers

Windows Logo Program RequirementsWindows Logo Program Requirements

Host side radiosMust be compliant with either WHCI or HWA specifications (and related specifications)

Must support isoch transfers

Device wire adaptersDWA's with exposed ports need to provide 500ma on all ports

Must support isoch transfers

Possible requirements around number of RPipes

DevicesWUSB devices must have a unique serial number

Devices must be compatible with both HWA and WHCI hosts

No plans to logo non-beaconing devices

Industry Compliance PlansIndustry Compliance Plans

Applications own compliance testingDefine 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 forlogo requirements
