The Siemens Information and Communication Mobile Group and Huawei Technologies set-up a joint venture to develop, manufacture and market TD-SCDMA technology. The new company, with an investment exceeding USD 100 million, will be based in Beijing. Siemens will hold 51% stake in the venture. The Chinese Ministry of Information Industry allocated 155 MHz spectrum to TD-SCDMA in October 2002, paving the way for the commercial use of the standard in China. Siemens has been working on TD-SCDMA since 1998 and will contribute its technology to the joint venture.
