China Telecom, a major telecome service provider, announced it has co-launched a CDMA industrial alliance Friday with more than 100 other companies from cell phone design and making to software and content providers.

Most of the member companies engaged in the non-profit alliance, initiated by China Telecom, were cell phone-related heavyweights such as Microsoft, Huawei and Samsung, said Yang Xiaowei, chairperson of the alliance, also vice president of the China Telecom Corporation.

Yang said as 3G and mobile internet technologies were introduced into everyday life, more individualistic and diverse demands for terminals have appeared.

"To meet these diverse demands, we need a highly concentrated and complementary industry between telecom service providers, chip makers, software platforms, terminal makers, and content providers," said Yang.

The alliance aims to streamline and coordinate industrial resources, helping member companies better cooperate in design and production of CDMA cell phones, and push forward product innovation, said Yang.

CDMA, or Code Division Multiple Access, is a method for transmitting multiple digital signals simultaneously over the same carrier frequency, and is most widely applied for cell phones.

Sales of CDMA terminals topped 32 million units last year, four times the amount in 2008, said Yang.
