Global TD-LTE Initiative (GTI) is a virtual open platform jointly founded by China Mobile, Softbank ( Japan), Bharti ( India), Clearwire (America), and Vodafone (UK), in an effort to advocate cooperation among global operators and industry partners to promote TD-LTE. Its aim is to solve key issues in the development of TD-LTE for increasing maturity and realize the convergence of TD-LTE and LTE FDD, eventually accomplishing the global deployment of TD-LTE. Since its foundation, GTI has made a series of effective moves, including motivating operators to expand network scale, accelerating the convergence of FDD/TDD for global roaming terminals, establishing new LTE roaming services, and promoting LTE-based service and application innovation. All these have enabled a great leap forward for TD-LTE, especially in terms of its globalization and industry development over the past two years. As of December 2012, GTI had 51 operator members from Asia, Europe, America, and Oceania as well as 44 industry partner members, growing into an influential global platform in mobile broadband technology.
