China Mobile and Clearwire Announce Agreement on TD-LTE Device Tests
China Mobile, the world's largest mobile network and customer base in the world, and Clearwire Corporation, a leading provider of 4G wireless broadband services in the United States, today announced, in conjunction with the Global TD-LTE Initiative (GTI), an agreement on common test specifications and joint interoperability testing (IOT) for TD-LTE devices in the global band configurations, including 2.3GHz to 2.7GHz. This important step forward will enable the companies to further accelerate development of the TD-LTE device ecosystem, especially in multi-mode, multi-band LTE devices.
Beginning this month, China Mobile, Clearwire and other GTI operators will establish 4G mobile broadband labs featuring a joint test platform and IOT environment for TD-LTE devices. The expected availability of the Quad-Band LTE 2.3-2.7 GHz spectrum range, in addition to certain other bands like 1.9GHz, as well as FDD and TD-LTE mobility interactions, makes it an ideal global configuration for mass 4G marketing worldwide. The labs will allow for the evaluation and qualification of commercial TD-LTE devices simultaneously in the U.S., China, and other promising markets, using common testing methodology, equipment, and infrastructure.
"The unmatched spectrum portfolio underlying Clearwire's planned LTE network has the potential to deliver faster speeds and with greater capacity than any current or proposed 4G network in the United States," said Dr. John Saw, chief technology officer of Clearwire. "Close collaboration with global wireless leader China Mobile accelerates the development of multi-mode multi-band TD-LTE and LTE FDD devices and provides the common test specifications OEMs, ODMs, chipset vendors and other critical component manufacturers need to rapidly develop and commercialize products to serve this massive global marketplace."
"Converged with LTE FDD, TD-LTE has become the major global 4G technology for unpaired spectrum," said Mr. Li Zhengmao, Vice President of China Mobile. "Our goal is to build efficient, low cost common infrastructure and terminal for different global markets with different spectrum to support mobile internet. By closely working with global operators such as Clearwire, we could leverage the experience, expertise, and scale to achieve this goal. This is also the reason why we create GTI and promote it jointly."
Clearwire plans to conduct its TD-LTE common IOT in Phoenix, AZ and Herndon, VA. China Mobile's testing will be carried out in Beijing and other TD-LTE trial cities. The joint test platforms will be open for device IOT by key participants in early 2012.
