Sprint and Samsung Declare Mobile WiMAX Technology Is Now Ready for Commercial Service

Samsung's Mobile WiMAX infrastructure and devices pass Sprint's
rigorous commercial acceptance criteria with flying colors
HERNDON, Va.--(Business Wire)--
Sprint (NYSE: S) and Samsung Electronics Corporation Ltd.
announced today that a new broadband wireless network offering the
speed and mobility of WiMAX has met Sprint's rigorous commercial
acceptance criteria including overall performance, handoff performance
and handoff delay. This key technical milestone has been passed after
extensive evaluation both in the XOHM(TM) lab environment and with the
commercial service network being built in the Baltimore and Washington
D.C. area. Sprint plans on launching commercial WiMAX service in those
cities later this year.

Samsung has been working with Sprint in the United States to test
and build Sprint's XOHM mobile broadband Internet service compliant to
the mobile WiMAX standard. Since finalizing a supply agreement in
2007, the two companies have steadily made progress on the extensive
project with previous key milestones including first data session in
the lab (June 2007), first data session on the live network (October
2007) and successful interoperability testing with multiple other
device vendors (April 2008).

"This is a major step towards launch readiness and Sprint is
extremely pleased with the performance of the mobile WiMAX network and
access devices from Samsung," said Barry West, XOHM president. "The
collaboration with Samsung and our other partners has created a WiMAX
ecosystem that has now proven that it can deliver this new technology
to the marketplace well ahead of any feasible alternative."

Last month, Samsung announced the introduction of several
WiMAX-enabled devices. The Express Card (E100 PC Card) and WiMAX
embedded UMPC (Q1 Ultra Premium Mobile PC) underscore Samsung's
position as the leading provider of end-to-end mobile WiMAX network
systems. With the technology proven to be ready, the Samsung mobile
WiMAX systems being deployed for Sprint in Baltimore and Washington
D.C. support the commercial introduction of XOHM service anticipated
to begin later this year.

"The wireless subscribers in the United States are ready to step
up to the next level of a truly broadband wireless network that
surpasses the performance of existing wireless networks today," said
Dr. Hwan Chung, senior vice president of Samsung Telecommunications
America. "Sprint's acceptance of Samsung's WiMAX technology shows
Samsung's strong commitment to meet our customers' needs for the most
reliable, seamless, and fastest wireless network. Samsung's mobile
WiMAX expertise will help Sprint answer the mobile broadband needs of
U.S. wireless subscribers." he added.

Samsung is the global leader in delivering mobile WiMAX
technologies and offers an end-to-end solution including chipsets,
infrastructure, mobile devices and consumer electronics, including
devices capable of accessing both mobile WiMAX and other wireless
technologies.

The XOHM business unit within Sprint specifically focuses on
developing the WiMAX ecosystem and standards to bring the latest
broadband wireless technology to the U.S. marketplace. Sprint is
utilizing the significant spectrum holdings at 2.5 GHz that were
combined in the Sprint Nextel merger to deploy mobile WiMAX technology
from Samsung and other vendors.
