LTE TDD is a major part of the ecosystem

The Global TD-LTE Initiative (GTI) was launched at MWC 2011. Founding members were China Mobile, Bharti Airtel, Softbank Mobile, Vodafone, Clearwire, Aero2 and E-Plus. According to the press release “GTI will focus on creating value for stakeholders across the TD-LTE ecosystem to promote the fast development of the technology, promoting the convergence of LTE TDD and FDD modes to maximize the economies of scale, and sharing ecosystem with other TDD technology, e.g. eXtended Global Platform (XGP) to establish a growth focused business environment.”

The initiative aims to bring together leading industry partners to steer the TD-LTE ecosystem as a major standard in mobile broadband technology & drive the development of next generation mobile broadband networks.
