Regulatory Timelines
US - Done
Europe - ECC TG3 is highly likely to propose a similar mask that proposed by MIC (-41.3 dBm/MHz with DAA below 5 GHz). Differences are (1) lower band edge (3.1 (EC) v.s. 3.4 (Japan) GHz), (2) no need of DAA for 4.2 to 4.8 GHz until 2010 in EC. Regulation is finalized by March 2006.
Asia - Korea would follow Japan without delay. China is speeding up their regulatory study. They watch the ITU-R meeting in October.
Japan - A draft spectrum mask has been proposed by MIC, and supported by the industry for further study. Current plan is to propose it at ITU-R and finalize the study by April 2006. DAA is necessary to maximize the UWB throughput. Simpler solution would be to drop awhole band (500 MHz), but the system performance would suffer.
Japan Regulatory Update
• Detection And Avoidance (DAA) is necessary to transmit at -41.3dB/MHz (average output power)
• Two techniques are required
• Detection
• Mitigation
• MB-OFDM has key basic features to realize DAA

Certified Wireless USB Promoters and Contributors
Benefits of Certified Wireless USB From the USB-IF
• Protocol designed from the ground up and optimized for a wireless medium
• Power management• Security and association• OS Support/Class driver protocol maintained• Data throughput • Bandwidth allocation/isochronous support
• USB-IF Certification and Logo program • Compliance and Certification testing
• Multiple suppliers of WiMeida MAC and Phy’s• One stop compliance testing for WiMedia UWB Radios and Certified
Wireless USB
• Logo from the USB-IF communicates the brand promise to the consumer
Certified 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 Mbps @ ~3M
• 110 Mbps @ ~10M
• Scalable architecture (up to 1Gbps and beyond)
• Power Management• Battery preservation very
important • PHY: 130-160mW for Tx/Rx
• Security• Highly SECURE device
association and authentication• Low encryption overhead,
minimal performance impact
• Ease of Use• Easy install and setup• Backwards Compatibility with
wired USB software• Low “device end” cost model
Host Wire Adaptor: HWACould be a simple dongle
Device Wire Adapter: DWA
USB 2.0 USB 2.0
Bringing Certified Wireless USB to Existing USB Products
State of the Art Adapters
Wisair 501 / 531 Chipset• 480 Mb• 8 Bands
• Association’s job:• Connect the owner’s devices the way the owner wants
them connected (IAA)• Security’s job:
• Match the security afforded by the USB wire• Protect data in-transit
Cable protects datain-transit
Cable Ends define user’s connection choice
Making it as easy and protected as the wire
Certified Wireless USB is a Wire Replacement
• Certified Wireless USB needs security
• Maintain Asymmetric Host-centric model
• Maintain USB model of cheap/simple devices
• Keep complexity confined to host
• Minimal microcontroller or ASIC state machine
• Symmetric Association
• Devices validates the host
• Host validates the device
• Certified Wireless USB encryption will use AES-128
Certified Wireless USB Security
Association Model Specification
• First time connection is the challenge• Association must be secure and easy• Two models are:
• Numeric compare• USB cable model
• Investigate Near Field Communication (NFC) for future implementations
• Association Model Specification • Definitive source for all technical and Implementation details• Everything you need to build Certified Wireless USB devices
• Enforced through USB-IF compliance testing & logo certification
Certification & Compliance
• WiMedia UWB radio supported by Certified Wireless USB
