POPULAR WIRELESS LOCAL AREA NETWORKS GAIN LARGE BOOST IN SPEED

New IEEE 802.11gT Standard Extends Data Rate of IEEE 802.11bT WLANs to 54
Mbps from 11 Mbps

PISCATAWAY, N.J., USA, 12 June 2003 IEEE 802.11bT, the most widely used
wireless local area network (WLAN) technology, has gotten a long-awaited
increase in speed through a new amendment to the IEEE 802.11 T standard
ratified by the Standards Board of the Institute of Electrical and
Electronics Engineers. The amendment, IEEE 802.11gT, raises the data rate of
IEEE 802.11b networks to 54 Mbps (megabits per second) from 11 Mbps.

The added transmission speed gives wireless networks based on IEEE 802.11b
(often called Wi-Fi) the ability to serve up to four to five times more
users than they now do. It also opens the possibility for using IEEE 802.11
networks in more demanding applications, such as wireless multimedia video
transmission and broadcast MPEG.

The new amendment allows IEEE 802.11g units to fall back to speeds of 11
Mbps, so IEEE 802.11b and IEEE 802.11g devices can coexist in the same
network. The two standards apply to the 2.4 GHz frequency band. IEEE 802.11g
creates data-rate parity at

2.4 GHz with the IEEE 802.11a standard, which has a 54 Mbps rate at 5 GHz.
(IEEE 802.11a has other differences compared to IEEE 802.11b or g, such as
offering more channels.)
"IEEE 802.11g gives WLAN suppliers and users added flexibility in choosing
systems that best fits their needs," said Stuart J. Kerry, IEEE 802.11
Working Group Chair. "Given the millions of 802.11b-based WLANs in place
worldwide, the market demand for the extension to 54 Mbps has been quite
strong.

"One reason for this is that the higher speed extends the use of this widely
deployed WLAN technology into a growing variety of home, consumer, business
and public networking applications. In addition to making IEEE 802.11b
networks more efficient, the new amendment ensures users that the equipment
in these networks will be interoperable."

In terms of the effort needed to create the new amendment, Kerry noted that
the IEEE 802.11 Working Group for Wireless LANs contains nearly 400
individuals with voting status who are affiliated with computer, networking
and software companies, as well as with consultant organizations and
academic institutions. "The members of the Working Group put forth a great
deal of effort to make this standard a reality," he said. "They are to be
congratulated for their achievement."

"The Wi-Fi Alliance applauds the IEEE for passing the IEEE 802.11g amendment
to the IEEE 802.11 standard," said Frank Hanzlik, Managing Director of the
Wi-Fi Alliance. "This very exciting achievement continues the evolution of
wireless LAN technology.

"In response to the amendment's approval, the Wi-Fi Alliance will be
announcing the first round of Wi-Fi CERTIFIEDT 802.11g products in the near
future. With over 700 Wi-Fi CERTIFIED products already available around the
world, we expect that the approval of this amendment will increase product
certifications and industry growth."

Geoff Thompson, Vice Chair of the IEEE 802 LAN/MAN Standards Committee and a
member of the IEEE Standards Board, says: "The current round of IEEE 802
standards passed by the Standards Board, which includes IEEE 802.11g and
IEEE 802.3af, "Data Terminal Equipment Power Via Media Dependent Interface,"
will help put networking equipment everywhere. These approvals are part of a
long-standing effort within the IEEE-SA to create advanced standards that
support cutting-edge applications so the industry continues to give end
users the capabilities they demand."

IEEE 802.11 standards form a family of specifications that define how WLAN
equipment should be produced so equipment from different manufacturers can
work together. IEEE 802.11g, "Higher Speed Physical Layer (PHY) Extension to
IEEE 802.11b," was developed by the IEEE 802.11 Working Group, which is
sponsored by the IEEE 802 ® LAN/MAN Standards Committee of the IEEE Computer
Society. For further information, visit: http://www.ieee802.org/.

About the IEEE Standards Association

The IEEE Standards Association (IEEE-SA), a global standards-setting body,
develops consensus standards through an open process that brings diverse
parts of an industry together. It has a portfolio of more than 870 completed
standards and more than 400 in development. IEEE-SA promotes the engineering
process by creating, developing, integrating, sharing and applying knowledge
about electro- and information technologies and sciences for the benefit of
humanity and the profession. For further information on IEEE-SA visit:

About the IEEE

The IEEE has more than 380,000 members in approximately 150 countries.
Through its members, the organization is a leading authority on areas
ranging from aerospace, computers and telecommunications to biomedicine,
electric power and consumer electronics. The IEEE produces nearly 30 percent
of the world's literature in the electrical and electronics engineering,
computing and control technology fields. This nonprofit organization also
sponsors or cosponsors more than 300 technical conferences each year.

About the Wi-Fi Alliance

The Wi-Fi Alliance (formerly WECA) is a nonprofit organization formed in
1999 to certify interoperability of IEEE 802.11 products and to promote them
as the global, wireless LAN standard across all market segments. The Wi-Fi
Alliance has instituted a test suite that defines how member products are
tested to certify that they are interoperable with other Wi-Fi CERTIFIEDT
products. These tests are conducted at an independent laboratory.

Membership in the Wi-Fi Alliance is open to all companies that support the
802.11 family of standards. The Wi-Fi Alliance now comprises over 180
members from the world's leading companies. These companies offer over 740
Wi-Fi CERTIFIEDT products. For more information, please visit
