Updated at 6.59pm, Thursday The US company Qualcomm CDMA Technologies scared Chinese competitors with a Monday announcement that it can now sell newly-designed mobile phone amplifiers, the Beijing-based Financial Daily reported on Wednesday. Chinese handset manufacturers worried of falling further behind in mobile telecommunications technology and wondered about increased licensing and royalty fees, said the newspaper. But, the report said, mainland manufacturers are happy to see new technology that can help them produce more advanced, smaller and more efficient phones, the newspaper said. Qualcomm worked with RF Micro Devices to develop the modules, which are designed to keep phones working well despite temperature extremes and low batteries. A power detector inside the new module eliminates the need for an external power detector, making smaller phones possible, according to Qualcomm statement. ''Even if we could develop CDMA technologies on our own, we would still have to pay Qualcomm royalties, because Qualcomm holds patent rights worldwide,'' said Geng Jiaguang, a media official from ZTX Telecom in Shenzhen. ZTX has signed a licensing agreement with Qualcomm to use its CDMA patents, and must pay a royalty for each handset it makes, Mr Geng said. CDMA, the common term for Code Division Multiple Access, is evolving technology due to make mobile conversations faster, clearer and safer for the human brain. Chinese mobile telecommunications equipment manufacturers are concerned because Qualcomm controls most CDMA technologies, according to Financial Daily. Most of the Chinese telecommunications equipment providers will adapt Qualcomm's CDMA technologies, said the paper.
