Wi-Fi Alliance Welcomes T-Mobile as New Sponsor Member

Leader in wireless communications services becomes Sponsor Member of global
certification and standards group







AUSTIN, Texas, Nov. 3 /PRNewswire/ -- T-Mobile has become a Sponsor Member of
the Wi-Fi Alliance and has appointed a Director to the organization's board. 
T-Mobile is one of more than 330 member companies that comprise the Wi-Fi
Alliance and joins Apple, Atheros, Broadcom, Cisco, Dell, Intel, Microsoft,
Motorola, Nokia, Sony Corporation and Texas Instruments as sponsor members of
the organization. Omar Hassan, who leads T-Mobile's Wi-Fi device technology
development, has been appointed to serve on the Wi-Fi Alliance Board of
Directors.

The Wi-Fi Alliance is an international non-profit organization whose
leadership in marketing, technology and advocacy programs helps ensure the
best user experience with Wi-Fi.  It was founded in 1999.  Its Wi-Fi
CERTIFIED(TM) program has been a driving force in the growth of the Wi-Fi
industry originating with computer networking and now evident in consumer
electronics and handsets.  ABI Research predicts that handsets will comprise
more than 25 percent of total Wi-Fi devices shipped this year, growing to
one-third of total shipments in 2012.

"T-Mobile has been an innovator and leader in advancing the popularity and
utility of Wi-Fi in handsets. As a Sponsor Member of the Wi-Fi Alliance,
T-Mobile exemplifies the importance of the mobile segment and operator
communities to the growth of the Wi-Fi industry," said Edgar Figueroa,
executive director of the Wi-Fi Alliance. "T-Mobile will make a valuable
addition to the leadership of Wi-Fi Alliance as a Sponsor Member of our
organization."

Among carriers, T-Mobile has long been a leader in the integration of Wi-Fi
technology. In 2007, the company was the first U.S. carrier to launch a
converged Wi-Fi/mobile calling service to consumers.  Earlier this month,
T-Mobile launched a converged Wi-Fi/mobile calling service offering for
enterprise customers.  About 40 percent of T-Mobile's device line-up offers
broadband data speeds over Wi-Fi.

"As a leader in the development of Wi-Fi voice technologies, we're pleased to
join the Wi-Fi Alliance as a Sponsor Member and to appoint Omar Hassan to the
board of directors," said Ray Froelich, director of product definition for
T-Mobile USA. "We strongly believe there's a big opportunity to align device
makers, chipset vendors, carriers and their infrastructure providers to create
new and innovative products and services that spark the broad adoption of
Wi-Fi in the mobile space."
