在作为中国自有知识产权的3G技术标准、作为被ITU所确定的三大主流标准之一的TD-SCDMA,由于其具有性能好、频谱利用率高、网络规划简单、覆盖范围广、建设和维护成本低,及在能够满足宽带多媒体通信要求的同时还可适用于传输非对称业务等特点,其已成为建设中国3G网络系统的最佳方案。作为TD-SCDMA系统关键技术之一的智能天线,国际上已将之作为当代以后移动通信技术发展的主要方向之一。
As a 3G technology standard of China’s own intellectual property, TD-SCDMA, one of the three mainstream standards identified by the ITU, has the advantages of good performance, high spectrum efficiency, simple network planning, wide coverage, Low maintenance cost, as well as being able to meet the requirements of broadband multimedia communications while also being suitable for transmitting asymmetric services and the like, and has become the best solution for building a 3G network system in China. As one of the key technologies of TD-SCDMA system, the smart antenna has been regarded as one of the main directions for the development of mobile communication technology in the world today.
