HSINCHU, TAIWAN — January 15, 2010 —In order to fully commit to the Chinese home-grown 3G communications standard TD-SCDMA and to specifically align with China Mobile on jointly expanding the TDD market, MediaTek, Inc., a leading fabless semiconductor company for wireless communications and digital multimedia solutions, today announced a strategic cooperation with AST Wireless (AST), a recognized developer of TD-SCDMA modem chips. With the synergy of both companies, this business cooperation aims at taking MediaTek’s 3G and B3G solutions to new high.

Continuous technological innovation in the TD-SCDMA industry is one of the major factors driving MediaTek to the overall leading position. MediaTek has previously unveiled the world’s first commercial TD-SCDMA HSPA chipset, Laguna-U, at the 2009 PT/WIRELESS NETWORKS COMM CHINA conference. The Laguna-U chipset is the successor of the industry’s first HSDPA chipset (Laguna) which was commercially used at the Beijing Olympic Games and can support HSDPA downlink up to 2.8Mbps. The Laguna-U is now in mass production to support the large-scale commercialization of HSPA in 2010. In addition, MediaTek’s TD-SCDMA chipsets have been taking a leading position in all previous terminals bids and deeply-customized mobile phones offered by China Mobile.

Moreover, the long-standing, fruitful cooperation with LeadCore is another important factor in the success of MediaTek in the TD-SCDMA market. JiChang Hsu, Executive VP of MediaTek stated, "Working with LeadCore to compete for several terminal procurements and stimulus programs offered by China Mobile has achieved excellent results. Over the past five years, the win-win cooperation between MediaTek and LeadCore has greatly contributed to the rapid growth of the TD-SCDMA market. The successful relationship with LeadCore and all cooperation projects will remain unchanged. MediaTek will maintain a close partnership with LeadCore to continue drive TD-SCDMA technologies toward extended international competitiveness."

With the rapid commercialization of the TD-SCDMA standard, the demand for various kinds of end-user terminal products increases. Through the strategic alliance with AST, MediaTek will deliver richer and more diversified products. Combined with its well-established wireless and multimedia technologies, MediaTek will make the TD-SCDMA industry stronger.
