[I hadn¹t noticed this announcement until today. Seems to me that we are
seeing a repeat of the mistakes of the early LAN standard wars. Lots of new
standards that have overly ambitious yet niche demand being forked off while
it might be better to focus on doing the minimal increments to Ethernet (or
in today's case 802.11) to meet the broad demand.

Of course this might also be how technical evolution works. The pressure of
these competing standards refines and tempers Ethernet / 802.11 to evolve
faster and cheaper... - Rob]

IEEE P802.20 Will Set Data Rates Above 1 Mbps for Mobile Users at Vehicular
Speeds to 250 km/hr

PISCATAWAY, N.J., 3 Feb 2003 Mobile broadband wireless access (MBWA) for
computers, personal digital assistants and other battery-powered devices is
set to take a major step forward. The next two years will see a standard
developed at the Institute of Electrical and Electronics Engineers (IEEE) to
create an air-interface that delivers service levels to mobile users
traveling at speeds as great as 250 km/hr that are comparable to wired
broadband systems, such as cable and DSL connections.

The standard, IEEE P802.20 (TM), "Standard Air Interface for Mobile
Broadband Wireless Access Systems Supporting Vehicular Mobility - Physical
and Media Access Control Layer Specification," will seek to boost real-time
data transmission rates in wireless metropolitan area networks from the
dial-up rates of today's cellular phones to a broadband experience of 1 Mbps
or more. By providing ubiquitous mobile broadband networking based on cell
ranges of up to 15 km or more, the standard will remove barriers for mobile
interactive voice, video and data services.

IEEE P802.20 will address MBWA in licensed bands below 3.5 GHz. It will
optimize airwave use for mobility and allow for many more simultaneous users
than existing mobile systems now accommodate. IEEE plans to have the
standard in place by the end of 2004.

"Our goal is to bring a true broadband experience to wireless users," says
Mark Klerer, 802.20 Working Group Chair and Executive Director of Standards
at Flarion Technologies. "In so doing, we hope to make MBWA a viable option
for transferring large amounts of data in real time via the Internet,
intranets and enterprise systems to mobile users within metropolitan area
networks.

"The standard will target sustained spectral efficiencies of more than 1
bit/second/Hz/cell, which is more than double that of today's systems. It
will promote fully QoS-enabled airlinks having high spectral efficiency and
low latency, giving users a high-speed wireless data experience equivalent
in quality to wired links."

The standard will provide for an efficient packet-based air interface with
high-speed downlink and uplink capabilities. In providing for low latency,
it will enable telephony using Voice over Internet Protocol (VoIP) and
activities needing rapid network response times, such as online gaming and
financial transactions. The standard also will support other IP-centric
applications, so the many native IP applications can be used without
alteration.

Individuals with expertise in mobile wireless systems, air interfaces and
mobility are invited to join the IEEE 802.20 Working Group. The group will
hold its next meeting at the IEEE 802 Plenary Meeting in Dallas, Texas, on
March 10 to 13. For more information on IEEE 802.20, visit:

This project is sponsored by the Working Group on Mobile Broadband Wireless
Access of the LAN/MAN Standards Committee in the IEEE Computer Society.
