BARCELONA, Spain, Feb. 25, 2013 (GLOBE NEWSWIRE) -- The Global TD-LTE
Initiative (GTI) today provided an update on successful global roaming trials
between major wireless operators in the United States, China and South Korea
as key developments in the organization's mission to promote a unified
GTI was formed by leading global operators to create value for stakeholders
across the TD-LTE ecosystem for early adoption of the technology and
convergence of TD-LTE and LTE-FDD. GTI includes more than 50 operators around
the world, and dozens of leading technology partners. The operators involved
in the new TD-LTE/LTE-FDD roaming trials include: China Mobile (mainland China
and Hong Kong), Clearwire (U.S.), SoftBank (Japan), KT (Korea), Bharti Airtel
(India) as key operator members of the coalition.
China Mobile recently completed global roaming trials with Korea Telecom and
China Mobile Hong Kong, and with Clearwire in both Hong Kong and mainland
China. The trials represent a major step forward in establishing a global
roaming configuration that creates a unified TD-LTE and LTE-FDD marketplace
around the world. In 2013, the GTI expects to conduct further roaming trials
involving SoftBank, Bhartil Airtel and others as the technical development of
TD-LTE/LTE FDD global roaming approaches critical mass.
With the commercialization of a global TD-LTE network, the need for global
roaming among TD-LTE networks is the key element of globalization of TD-LTE.
The GTI Roaming task force provided great support to perform the TD-LTE
roaming testing among GTI members.
Based on the China Mobile International Limited (CMI) IPX trial network, the
international roaming test between China Mobile's TD-LTE network in China and
its partners has provided some initial results. The TD-LTE data roaming
testing between the China Mobile in Hong Kong (CMHK) and Clearwire in the
United States has been completed successfully. In addition, China Mobile is
conducting TD-LTE roaming testing with partners such as India's Bharti,
Japan's SoftBank and South Korea's KT.
In 2013, China Mobile will continue to conduct roaming tests of TD-LTE with
more international partners to accelerate the ecosystem development of the
"Successfully establishing a platform on which to base global LTE roaming has
been an important long-term goal for Clearwire and our GTI partners," said Dr.
John Saw, Chief Technology Officer of Clearwire. "Building this framework,
with the TD-LTE and Band 41 configuration, will accelerate a development cycle
that we believe will provide operators around the world significant benefits
as the move toward LTE continues. We're proud of our leading role in driving
the development of a unified global marketplace for LTE."
"The GTI's successful completion of roaming trials between TD-LTE and LTE-FDD
network technologies is a major step towards providing worldwide interoperable
LTE services," said Alex Sinclair, Chief Technology Officer at the GSMA. "The
mobile industry has a responsibility to ensure that 4G enables a seamless
experience for users, and the capability to roam on any LTE network is a
fundamental part of that responsibility."
