近日,由北京信威通信技术有限公司、重庆市电信管理局、重庆高新技术产业开发区合资组建的重庆信威通信技术有限公司挂牌成立,以此标志SCDMA无线接入系统在重庆落户。重庆信威通信技术有限公司目前主要生产SCD-MA无线接入系统。该系统是一批海外留学生的科研成果在国内研究和开发的具有国际超前同类技术的新产品,也是近年来在无线接入技术上出现的一种全新技术。该系统主要采用了同步CDMA、智能天线和软件无线电三种关键技术,具有目前国际上最高的无线频谱利用率。使用SCDMA无线接入系统能享受与使用有线系统同样的服务,其覆盖半径可以达到10km左右。在原邮电部、邮电科学研究院的积极支持
Recently, by the Beijing Xinwei Communication Technology Co., Ltd., Chongqing Municipality Telecommunications Authority, Chongqing Hi-Tech Industrial Development Zone, a joint venture of Chongqing Xinwei Communication Technology Co., Ltd. was established to mark SCDMA wireless access system settled in Chongqing. Chongqing Xinwei Communication Technology Co., Ltd. currently produces SCD-MA wireless access system. The system is a group of overseas students’ research achievements in the domestic research and development of new products with the international advanced similar technology, but also in recent years in wireless access technology appears a new technology. The system mainly uses synchronous CDMA, smart antenna and software radio three key technologies, with the highest international wireless spectrum utilization. Using SCDMA wireless access system can enjoy the same service with the use of cable systems, the coverage radius can reach about 10km.
