时分-同步码分多址(TD-SCDMA)具有频谱利用率高、系统容量大、系统设备成本竞争优势强、移动速度满足国际电信联盟(ITU)要求、网络建设费用低、适合移动互联网非对称数据业务应用和全球漫游等特点。因此,在第三代移动通信系统(3G)的市场竞争中,未来采用TD-SCDMA技术和设备的移动通信运营商具有明显优势。TD-SCDMA产业的发展始终得到中国政府的大力支持。在TD-SCDMA产业联盟的努力下,TD-SCDMA的开发进度正显著加快。
Time-division-synchronous code division multiple access (TD-SCDMA) has the advantages of high spectrum utilization, large system capacity, strong system equipment cost competitive advantage, mobile speed meeting the requirements of International Telecommunication Union (ITU), low network construction cost, suitable for mobile Internet asymmetry Data business applications and global roaming and so on. Therefore, in the market competition of the third generation mobile communication system (3G), future mobile communication operators adopting TD-SCDMA technology and equipment have obvious advantages. The development of TD-SCDMA industry has always been the strong support of the Chinese government. In the TD-SCDMA industry alliance efforts, TD-SCDMA development is significantly accelerated.
