An Overview of Wireless Data Standards for Portable Applications and the Potential of Ultra-Wide Band as a High Speed Wireless Radio Technology

Dr. Robert F. Heile
Chair of IEEE 802.15 Working Group on WPANs, Chairman of the ZigBee Alliance, CTO, Appairent Technologies Abstract

司 会  小川 博世 (通信総合研究所)
Wireless applications have become an increasingly important part of daily life. We are very familiar with our cordless phones, our remote controls and our mobile phones and cannot imagine what our lives were like without them. Wireless data is becoming increasingly important as well. With the advent of 802.11b and Wi-Fi almost four years ago, we are becoming addicted to untethered access to the Internet and other digital services both at home and in public places. Current standards like 802.11, have focused on PC centric applications. Just emerging are applications focusing on home entertainment leading to a whole new set of requirements for wireless data networks. Today's wireless solutions need speed, support for high quality AV streaming, with a focus on low power consumption, plug and play, interoperability, location based services, and self organizing networks.

This talk will provide a brief overview of 802.11 networks and potential future directions these networks might take. The principal focus will be on the emerging 802.15 standards and related industry Alliances such as WiMedia and ZigBee and will address the unique requirements of multimedia applications and wireless home networks which are intended to do more than just deliver Internet access. Home entertainment is the most demanding application of all. Guaranteed quality of service is essential for the delivery of video and audio. As the need to distribute multiple HDTV streams materializes in the future, so will be the need for very high speeds. Such speeds are not a problem for the wired world but present real challenges for the wireless world operating in unlicensed spectrum.

The current 802.15.3 solution, which uses the 2.4GHz band can deliver 50Mbps reliably, maybe double that if a second channel is used. While it is fine for today, we need to plan for a faster tomorrow and that is the job of the recently formed Task Group 3a in 802.15, which is chartered to look for faster alternative radios for use with the 802.15.3 MAC layer. One of these alternative radio technologies is Ultra-Wide Band.

UWB, when used in conjunction with the 802.15.3 MAC layer, holds a lot of promise for achieving the very high speeds needed for future AV applications at reasonable cost and complexity.

ユビキタスコンピューティング環境の実現にむけて
Toward the Realization of the Ubiquitous Computing Environment

ユビキタスコンピューティング環境では、身のまわりのあらゆるモノにコンピュータが入り、それらがネットワークで相互接続され、協調しながら我々の生活をかげから支えてくれる。ポストインターネット、ポストPCの時代の新しいIT のパラダイムとして、私が早くから提唱してきたこのようなユビキタスコンピューティング (どこでもコンピュータ) が注目されている。本講演では、ユビキタスコンピューティングを実現するための技術とその応用、更には社会的影響や将来の可能性などについて述べる。

In the ubiquitous computing environment, computers will be incorporated into all sorts of things around us, and they will be mutually connected together via networks and support our lives from the shadows while cooperating with each other. As the new IT paradigm of the post-Internet, post-PC age, this kind of ubiquitous computing, which I have advocated from early on as "computing everywhere," has been drawing attention.
In this lecture, I will describe the technologies for realizing ubiquitous computing and their applications, and, furthermore, social influences and possibilities for the future.
