BARCELONA, Spain -- 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 TD/FDD-LTE market.
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.
