I think we'll have to put in a motion from the floor, at the AGM, to get you a hat.<g>

Re: WOFDM and mobile communications, saw this interesting presentation while cruising IEEE sites:
The IEEE North Jersey Chapter of the Vehicular Technology Society is presenting a talk by Nelson Sollenberger on "High-Speed Wireless Data Access based on Combining EDGE with Wideband OFDM" on Wednesday, 13 Oct 99.
About the Talk:
The rapid growth of wireless voice subscribers, the growth of the Internet, and the increasing use of portable computing devices suggest that wireless Internet access will grow to be a major area of telecommunications services. Data transmission rates are growing rapidly in fixed networks with the use of WDM in backbone fiber networks and the introduction of cable modems. In parallel with the expanding availability of high-speed transmission capabilities, increasingly demanding Internet applications and user expectations have emerged. Combining Enhanced Data-rates for GSM Evolution (EDGE) with Wideband Orthogonal Frequency Division Multiplexing (WOFDM) in an asymmetrical solution to address the challenges of high-speed data rates combined with wide-area coverage and good quality for wireless packet data services will be discussed in this talk. WOFDM can potentially support peak data rates on digital cellular downlinks up to several megabits/sec. EDGE is more attractive for uplinks to support several hundred kilobits/sec. Network based dynamic packet assignment can provide very high spectrum efficiency, and WOFDM supports good radio performance with inherent frequency diversity and support for interference suppression techniques.
About the Speaker:
Nelson Sollenberger is employed at AT&T Labs-Research where he is Division Manager in the Wireless Systems Research Department His department performs research on next generation wireless systems concepts and technologies including high speed transmission methods, smart antennas and adaptive signal processing, system architectures and radio link techniques to support wireless multimedia and advanced voice services.
Nelson received his Bachelor's degree from Messiah College (79) and his Master's degree from Cornell University (81), both in Electrical Engineering. From 1979 through 1986 he was a member of the cellular radio development organization at Bell Laboratories. At Bell Laboratories, he investigated spectrally efficient analog and digital technologies for second-generation cellular radio systems. In 1987, he joined the radio research department at Bellcore, and he was the head of that department from 1993 to 1995. At Bellcore, he investigated concepts for PACS, the Personal Access Communications System. In 1995, he joined AT&T. Nelson is an IEEE Fellow and an AT&T Fellow.

It seems to me that this reverts to Hatim's previous statements on the applicability of WOFDM to mobile applications.
