China has developed the first WCDMA mobile phone chip

Jointly developed by Southeast University and East communications company Noah3000 mobile phone chip, successfully passed the system testing including call and data transmission service, the results showed that the performances of the chip meets the requirements of the international standard WCDMA. This indicates that China already has the ability to develop all the core technologies of the world's three largest mobile communications capabilities.

Noah3000 mobile phone chip testing system successfully, is an important development in Southeast University and East communications company, the joint national "863" special projects for development of integrated circuit, is a significant achievement since 2003 the school has successfully developed the first domestic mobile phone chip Noah2000 according to CDMA2000 international standards and formed a series of products made after the.

The reporter learned from the Southeast University, Noah3000 mobile phone chip set of 16 domestic and foreign patents as a whole, multipath energy window technology it uses, can make the mobile phone can achieve excellent performance in poor communication conditions, but also to provide mobile phone very high speed data service stable, improves the transmission rate than CDMA2000 chip 2-3 times. It uses a variety of low-power design technology, can significantly improve the phone's standby time. As a result, equipped with a Noah3000 chip phone will have a faster connection speed and information exchange rate, better communication effect, longer standby time and more additional features, etc..

WCDMA international standard is the upgrade standard of the existing GSM system, which has a broad market prospect in the world. Southeast University East communications company took the lead in the domestic development of the WCDMA and CDMA2000 mobile phone chip, mobile phone chip and other domestic companies developed in line with the international standard TD-SCDMA put forward by our country independently, marking the ability of all our core technology is fully equipped with the development of mobile communications standard of three.

It is understood that the National Mobile Communications Research Laboratory of Southeast University is a National Key Laboratory of mobile communications research and development specializing in domestic only, in the mobile communications research and development has been at the forefront of the country. The last century since the mid 90s, the national laboratories undertook a series of major research projects, played a central role in the domestic research and development of the first GSM, CDMA and the third generation of mobile communication testing system, in order to promote domestic mobile communication technology to catch up with the world advanced level and made important contributions.
