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)
Chair Hiroyo Ogawa (CRL) |
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. |

Toward the Realization of the Ubiquitous Computing
Environment
Ken Sakamura (The Univ. of Tokyo)
Chair Hiroyo Ogawa (CRL) |
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. |
