Siemens leading the way for China’s 3G wireless standard

Promising position in the world’s largest wireless communications market.

Munich, Feb 10, 2006, Siemens Communications sees clear confirmation of its business strategy for China after the Chinese government officially declared TD-SCDMA as the national 3G standard. The company has developed TD-SCDMA for the local market, working with Chinese partners from the start. The solution has proven itself in various tests, and the network and various end-user devices interact smoothly. Through TD-Tech, a joint venture with its partner Huawei, Siemens will be able to ship TD-SCDMA equipment beginning in mid-2006. In addition, Siemens is one of the leading vendors for W-CDMA. This 3G standard is also expected to become established in China. The 3G licences are still to be issued.

Since 1998, Siemens Communications has invested more than 170 million euros in developing the TD-SCDMA standard, which is recognized by the ITU, and has already successfully tested many products for use in TD-SCDMA networks together with the Ministry of Information and Industry (MII). These products include base stations and their control hardware, and operation and maintenance centers in telecommunications networks. Since mid-2005, vendors of end-user devices have been able to test their products and the products’ interoperability with new applications in an open laboratory. The most recent tests have demonstrated the smooth interaction between TD-SCDMA technology and mobile phones and laptops. The best results were achieved by the joint venture partners Siemens and Huawei and their technology.

The distinguishing features of the Chinese 3G standard are that it uses the 155 MHz frequency spectrum specified for China with outstanding flexibility, transmits large volumes of data without problems and offers a large radio range. That makes TD-SCDMA very suitable for use both in large cities and in rural areas as a technology to provide widespread coverage.

Siemens is very well positioned in the Chinese market:
“We are pursuing a dual strategy in China. First, we have outstanding W-CDMA know-how and the sales successes to match. Second, we assumed a pioneering role for TD-SCDMA in China at the right time. We can deliver the infrastructure as soon as the Chinese government has awarded the licences to carriers. As a result of our systematic strategy, we are very well prepared for the next milestone, the award of the licences,” says Christoph Caselitz, head of Mobile Networks at Siemens Communications.

Together with its partner NEC, Siemens sets the tone in the global market for W-CDMA technology. A report by the independent MM Research Institute in Tokyo from the year 2005 ranked NEC/Siemens – with its world market share of 30 percent – as No. 1 in the 3G/W-CDMA market for commercially installed base stations. More than 90 percent of all W-CDMA subscribers worldwide communicate using network technology from Siemens/NEC.
