ST-Ericsson’s Chinese subsidiary, T3G, has been picked by China Mobile as a key technology partner for the development of its high-end and low-cost mobile handsets, supported by TD-SCDMA 3G standard.

According to the terms of the deal, ST-Ericsson, a 50/50 JV between Ericsson and STMicroelectronics, will set up a new low-cost platform to support its customers to offer affordable TD-SCDMA devices to China Mobile consumers.

“Although ST-Ericsson is a recent joint venture, our subsidiary T3G has been actively developing platforms for the mobile standard for more than six years, achieving an impressive record of world firsts in bringing innovation to China,” said Alain Dutheil, President and CEO of ST-Ericsson.

In addition, ST-Ericsson will also support customers to develop high-end mobile phones, based on existing and new platforms such as the T7210, which will allow consumers to enjoy high-speed broadband and multimedia services.

“Our dedicated local R&D team, as well as our strong commitment to continuous innovation and close cooperation with customers, will enable China Mobile to offer a broad range of handsets for the mass market as well as for the high-end segment,” added Dutheil.

Meanwhile, ST-Ericsson will also help four of its clients to commercialize their mobile phones during next year.

ST-Ericsson’s T7210 mobile platform supports TD-SCDMA dual-band in 2010-2025MHz/1880-1920MHz frequencies.
