　　At present, the main global mobile phone baseband manufacturers include Texas Instruments or TI, Ericsson Mobile Platform, Qualcomm, MTK, NXP, Freescale, Infineon, Broadcom and Spreadtrum. Depending on the cooperation with Nokia in 2G Era, TI created a win-win situation for the two. However, TI seems to have underestimated the coming of 3G era and is lack of 3G baseband products, besides large quantity of application processors put on the market. So far, TI has launched only one 3G baseband product, OMAPV2230, which is not that popular in the market. In the whole year of 2007, TI did not roll out any 3G baseband product and in fact, only launched 1-2 new 2G products. No wonder TI is seeking cooperation with Ericsson Mobile Platform or EMP, to jointly develop 3G baseband, but it seems a bit late.

1. Overview

The core algorithm of Smart antenna is adaptive beamforming antenna technology which has been developed at 1960s, used in radar antenna array, in order to enhance the performance of radar and electronic warfare capabilities. In the mid-1990s, smart antenna technology began to be considered in wireless communication systems. Firstly United States corp. Arraycom implemented the smart antenna in the Time Division Multiple Access PHS system;

In 1997, Beijing Xinwei Telecom Technology Co., Ltd. Which companies from China Ministry of Information Industry Academy of Telecommunications Technology has successfully development SCDMA wireless subscriber loop System based on smart antenna technology, In addition, a large number of universities and research institutions of china and other country have begun to carry out a wide range of smart antenna beamforming algorithm.

In year 1998, China submitted TD-SCDMA RTT proposal to the ITU's, which is the CDMA communication system first time based on smart antenna technology.

SHANGHAI, China, /Xinhua-PRNewswire-FirstCall/ -- Spreadtrum Communications, Inc. (Nasdaq: SPRD - News), one of China's leading wireless baseband chipset providers, today reports that China Mobile (CMCC) has announced commercial deployment of TD-SCDMA technology beginning in April. TD-SCDMA is a 3G wireless network standard developed by the China Academy of Telecommunications Technology (CATT) in collaboration with Datang and Siemens and endorsed by the Chinese government.

Dr. Ping Wu, Chairman & Chief Executive Officer, said, "We are very excited with this key development in the commercialization and deployment of TD-SCDMA technology in China. Our friends, customers, and partners are also extremely pleased to see TD-SCDMA technology reach this milestone. Today's announcement demonstrates China Mobile's strong commitment to commercialize the TD-SCDMA technology and includes a host of measures to facilitate market acceptance of this technology including attractively priced calling plans, availability of six subsidized handset models, availability of USIM cards for consumers who purchase TD-SCDMA handsets through other channels, demo centers in eight cities, financial incentives for resellers, publicity campaigns, and after-sale customer support.
