2 UWB Initiative Industry Updates UWB PHY and MAC standardization Convergence layer for multiple protocols WUSB Protocol 180+ companies (PC, CE, Cellular Players) Endorsed MBOA PHY May 04 Endorsed MBOA PHY, MAC Feb Protocol Endorsed WiMEDIA Platform Sept 04 2

3 Overview Wireless USB Platform Various technology solutions running over the common UWB radio platform IP Networking (UPnP) Non Non IP Peer Peer to to peer (W1394) Other Applications Peripheral Interconnect (WUSB) (WUSB) Wireless USB Promoters Lowest cost PC peripherals Common UWB Radio Platform Convergence Layer UWB MAC UWB Phy WiMedia Common Ultra Wideband Radio Platform MBOA 3

4 Wireless USB Promoter Group Formed in February First High Speed personal wireless interconnect Based on MB OFDM UWB Radio from MBOA Promoter Companies Agere,, HP, Intel, Microsoft, NEC, Philips and Samsung 4

5 WUSB Promoter Group Legal Structure Promoter Companies Overview Contributor Level 90+ Contributors joined expected to grow Adopter Level Broad industry adoption after final specification is completed USB IF is trade association for WUSB 5

6 Overview Right Place to Start USB is the de facto standard for personal connectivity of PC s, migrating into CE and mobile devices Good early reaction from key industry players to WUSB concept Wireless USB builds on the momentum established in wired USB Number of Wired USB Products Shipped per Year (Millions) Over 1 Billion units in 800 the installed base 700 today, growing to 3.5 Billion by Source: Cahners In Stat Group, 2002 Camcorders PCs Peripherals Consumer Electronics Wired USB Attach Rates for Key Device Types 96% USB enabled by 06 External Storage USB enabled by 06 Digital Cameras 95% USB enabled by 06 Source: In Stat/MDR Group, % USB is the most successful interface in the history of the PC Source: Brian O Rourke/Instat MDR 6

7 The Vision Wireless USB Usage Models Replacing Interconnect Cables CE Segment PC Segment Mobile Segment or Eliminate cable hassles for portable device and content upload/display Ease install/configure of next generation digital displays and home theater Support many multimedia streams (HDTV, audio, etc.) Eliminate USB cables Low cost implementation for portable devices Unwire high data rate devices Applicable to the digital home and the digital office 7 Enable high data rate applications Wireless notebook docking station Hand held and notebook wireless linkage w/ resource sharing Wireless USB is the first high speed personal wireless interconnect Wireless AV display from Communications notebook and Technology handhelds Lab

8 Architecture Overview Technology Requirements Summary Bandwidth 3 meters Scalable architecture & protocol (up to1gbps and beyond) Power management (battery preservation) Sleep/Listen/Wake, Conserve under operation Tx/Rx power management Security (secure connection) Device secure association & authentication Low overhead, minimize performance impact Encryption through application Ease of Use (similar to wired USB) Easy installation & setup Backward compatible to wired USB Low cost implementation Communications Technology 8 Lab

9 WUSB Technology Technology Requirements Topology Up to 127 devices Hub and and spoke connection relationship Connection model is a wire replacement Point to to point connections Between WUSB host & peripheral WUSB Cluster WUSB Host with one or more peripherals (up to 127) WUSB Clusters may co exist within an overlapping spatial environment 9 Host scheduled data communications Dual Role Device connectivity

10 Architecture Overview Technology Requirements Wire Adapter Bringing Wireless USB to existing USB devices & hosts. USB2.0 USB2.0 Host Wire Adaptor: HWA 10 Device Wire Adaptor: DWA

11 Overview Accomplishments Broad Industry Support is underway WUSB prototypes are in development WUSB SIG is legally formed Contributors joined in high volume (90+) WUSB Spec is at rev 0.91a Wireless USB Logo defined and TM filed WW Public Web site is live Two Industry WUSB specification reviews F2F held 11

12 Timeline and Next Steps Market Trends Specs and Products Phy standard completed in Q MAC standard completed in Q WUSB spec completed in Q UWB and WUSB Silicon in 2005 End user products at end of 2005 PC and CE will lead the adoption Mobile market will follow Market adoption Add on modules for host USB2.0, PCI, PCIe, ExpressCard DWA for device Internal modules PCI, PCIe (peripherals and CE) WLAN and UWB on the same module UWB is making fast progress 12
