Global Roaming for TD-LTE

Posted by Sam Churchill on

Alcatel-Lucent and China Mobile are to unveil an innovative new member of the lightRadio’ family that will help accelerate deployment of 4G TD-LTE technology across China, the largest mobile market in the world.

LightRadio Metro Radio – co-developed by Alcatel-Lucent and China Mobile – will be launched on February 26 at the Global TD-LTE Initiative’s (GTI) “TDD Night” during Mobile World Congress 2013 in Barcelona.

Available now for large-scale commercial deployment in China Mobile’s first trial TD-LTE network, which spans 13 cities in China, lightRadio Metro Radio will bring legitimate 4G services to residents in densely populated areas of Shanghai, Nanjing and Qingdao.

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 and realize the convergence of TD-LTE and LTE FDD, for the global deployment of TD-LTE.

The 6th Global TD-LTE Initiative (GTI) workshop was held in Barcelona, Spain on Feb. 21-22, ahead of Mobile World Congress. More than one hundred representatives from China Mobile, Vodafone, Softbank, Clearwire etc. participated in this 2-day meeting, managing to promote the solutions for commercialization of TD-LTE and convergence of TD-LTE and LTE FDD.

Roaming between Clearwire, China Mobile, and KT’s TD-LTE network has been demonstrated, and between TD-LTE and FDD LTE, GTI will scale up for further growth of the global roaming of LTE TDD/FDD data services.

China Mobile and KT conducted roaming trials between China Mobile’s 2.3 GHz and 2.6 GHz TD-LTE bands, also known as Band 40/38, and KT’s 1.7/1.8 GHz FDD-LTE bands, also known as Band 3. NTT DoCoMo, China Mobile and KT have announced a new partnership on both Wi-Fi and NFC roaming plans across their respective countries of Japan, China and Korea. The new arrangement will allow international mobile and/or Wi-Fi operators to roam into Wi-Fi® hotspots in Japan, China and Korea through a single contract and a one-stop connection

China Mobile is also conducting TD-LTE roaming testing with partners such as India’s Bharti, Japan’s SoftBank and South Korea’s KT. India’s Bharti is expected to show roaming capabilities between its Band 40 TD-LTE service and China Mobile’s Band 40/38 TD-LTE service. The success rate of over 1400 tests on 5-mode 12-band MiFi available for the entire band of 2.6GHz reached 98%, with power consumption same as the level of FDD LTE.

The Global TD-LTE Initiative also hopes to unite with GSMA to promote and support international automobile enterprises with TD-LTE based Internet of Vehicles.
