China develops world's first TD-SCDMA 3G mobile phone set ( 2003-11-03 09:48) (Xinhua) China has developed its first 3-G mobile phone set, and it is also the first TD-SCDMA phone of its kind in the world, its developers say. Professor Zhen Jianhong, in charge of the development project sponsored by the Chongqing Institute of Posts and Telecommunications, said the phone was developed independently with all the intellectual property rights. Compared with GSM, TDMA digital mobile phones, or 2-G mobile phones, and their predecessor analog mobile phones, the 3-G phones are a more powerful telecommunication tool. The 3-G mobile phone is widely considered as the future of mobile telecommunications, capable of providing such services as Internet webpage browsing, teleconferencing, and electronic commerce. Chinese telecommunications giant Datang has set up an experimental network for TD-SCDMA mobile phones in Jiangbei District in Chongqing, southwest China. The developers are seeking cooperation with domestic mobile phone producers and operators to commercialize the product. The first group of the phones are expected to be available in 2005. The phone was made according to TD-SCDMA, the technological standard formulated by China and approved by the International Telecommunications Union of the United Nations as one of the three standards for 3-G mobile phones. The other standards refer to WCDMA proposed by European companies and CDMA 2000 by the United States. CDMA refers to code division multiple access.
