The GTI has succeeded
The Global TD-LTE Initiative (GTI) was formed in 2011 to promote the interoperability between LTE FDD and LTE TDD. A secondary goal was to ensure that LTE TDD wouldn’t be a Chinese-specific technology. Undoubtedly, China Mobile’s ongoing network rollout (which is expected to exceed 200,000 base stations and cover more than 300 million people by the end of 2013) is important to LTE TDDâ€™s success. However, China Mobile now has many allies in this effort and the GTI can claim that it has succeeded in achieving its goal.
This year’s GTI conference, held at MWC 2013, was a whoâ€™s who of mobile ecosystem players. Samsung, Qualcomm, Ericsson, Nokia, and Nokia Siemens Networks all spoke of their support for the technology. There was even mention of Verizon Wireless wanting multi-mode LTE smartphones to enable roaming with China Mobile and other LTE TDD operators. LTE TDD operators can now be found throughout the world, including in Poland, Sweden, Saudi Arabia, Japan, and, before the end of 2013, in the US.
So if the goal of the GTI was to ensure multi-mode LTE support and a global ecosystem, there is no doubt that it has succeeded.
