Wireless Communications and Networking Conference WCNC 2003 Technology

Wireless Communications and Networking Conference (WCNC’ 2003) Technology Panel: Ultra-wideband (UWB), An overview of the IEEE 802. 15 Call For Proposals Wednesday, March 19 2003, 11: 10 am 12: 30 pm 19 Mar 03 Ian Gifford <igifford@xtremespectrum. com> 1

What’s a UWB? • UWB devices operate by employing very narrow or short duration pulses that result in very large or wideband transmission bandwidths. • Three types of UWB devices: – Communications and Measurement Systems – Imaging Systems – Vehicular Radar Systems 19 Mar 03 Ian Gifford <igifford@xtremespectrum. com> 2

UWB Panel Summary • This technology panel will focus on ultra-wideband (UWB) and the current status from the preceding weeks IEEE 802 Plenary Meeting and the initial round of Physical Layer proposals received on the IEEE 802. 15 Call For Proposals; most of which are based on UWB. • The attendees will be provided a short overview and summary of the IEEE 802. 15 Task Group 3/3 a and their UWB studies to date. • The Panel will then discuss the UWB proposals, address various UWB schemes, their addressability to the call and/or the emerging regulatory framework, next steps, Project 802. 15. 3 a timeline, etc. • Additionally, we will briefly overview the latest worldwide standards and regulatory activities. 19 Mar 03 Ian Gifford <igifford@xtremespectrum. com> 3

UWB Panel Agenda • The Technical Panel Chair introduces the panel organizer and moderator (bio). • Then the moderator takes over and introduces the panelists (e. g. bios). • Panelists make their presentations, 5 -10 min: – Julius Knapp – USA regulatory process and current status – Bob Huang – European regulatory process and current status – Ryuji Kohno – Japanese regulatory process and current status, Academia, and CRL 802. 15. 3 a Alt PHY Proposal – Jeffrey Foerester – Intel 802. 15. 3 a Alt PHY Proposal – John Mc.

Scope • This project will define an alternative PHY clause for a higher data rate amendment to standard 802. 15. 3. 19 Mar 03 Ian Gifford <igifford@xtremespectrum. com> 32

Purpose • The intent of this project is to provide a standard for a low complexity, low cost, low power consumption alternate PHY for 802. 15. 3 (comparable to the goals for 802. 15. 3). The data rate will be high enough, 110 Mb/s or more (see 18 a), to satisfy an evolutionary set of consumer multi-media industry needs for WPAN communications. The project will address the requirements to support multimedia data types in multiple compliant colocated systems and also coexistence (18 b). 19 Mar 03 Ian Gifford <igifford@xtremespectrum. com> 33
