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 TD-LTE industry. "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." LTE TD/FDD International Summit and Mobile World Congress Showcase The GTI will hold the 7 th LTE TD/FDD International Summit at Mobile World Congress on Tuesday, 26 February from 9:00 a.m. to 11:00 a.m. in Hall 8.0 Theater District, Theatre B. Members of the press are encouraged to attend the event. Chairmen and CEOs from major wireless companies, including China Mobile, Bharti Airtel, Clearwire, Samsung, Qualcomm, Ericsson and Nokia Siemens Network will discuss the convergence of LTE TD/FDD and the acceleration of TD-LTE deployments in global markets. They will also discuss the proliferation of commercial TD-LTE networks, the challenges operators face deploying affordable multi-mode and multi-band terminals, and the creation of a unified market by enabling global roaming.
