Certified Wireless USB from the USB-IF Jeff Ravencraft USB-IF President & Chairman Wireless USB Promoter Group Chairman Intel Corporation Key Messages The WiMedia UWB Ecosystem is delivering on its promise Certified Wireless USB products using WiMedia radios will be commercially available in the next 12 months These products will be: Compliant to the specifications Interoperable Adopted broadly in all segments
WiMedia UWB Ecosystem Convergence layer for multiple protocols 180+ companies (PC, CE, Cellular Players) UWB PHY and MAC standardization WUSB Protocol 100+ Endorsed MBOA PHY, MAC Feb 04 Endorsed WiMEDIA Platform Sept 04 UWB in the Digital Home Local high throughput delivery Wired / Wireless Broadband Wired / Wireless Wired /Wireless Wired / Wireless Long range delivery wired & wireless Long range delivery wired & wireless Wired / Wireless Wired / Wireless UWB complements long range delivery to to Intelligent Centers with with high spatial capacity and and high speed interconnectivity
WiMedia Alliance UWB Platform &/or &/or &/or WiNET WiMedia UWB Radio Platform UWB MAC & Policies UWB PHY (MB-OFDM) 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 a whole 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 The Digital Home Experience
