摘要
目前,国际上承认的3G标准有三个,分别是WCDMA、CDMA2000和TD-SCDMA.其中,WCDMA标准支持的国家最多,所有的欧洲国家全部支持,它也是全球获得3G牌照最多的标准,诺基亚、爱立信等公司是主要技术商;CDMA2000为美国、日本、韩国等国家主要支持的标准,韩国的LG等公司已经获得相关牌照,美国高通公司是主要技术支持者;TD-SCDMA是中国大唐电信拥有自主知识产权的标准,目前仍在研发过程之中,还没有任何一家运营商明确表示要采用该标准.可以看出,TD-SCDMA是这三个3G标准中资历最浅、资源最少的一个,处于明显的不利地位.在这种状况下,人们不禁疑惑,敢问TD-SCDMA路在何方?
As we mention the development of 3 G,We always pay special attention to the three major standards: WCDMA, CDMA2000 and TD-SCDMA. Now the standard of WCDMA Is accepted by more countries all over the world. Especially in Europe all countries will adopt it in the deployment of 3C What's more, now most owners of 3G's license show interest in WCDMA. Its main technical Supporters include Nokia and Erisson. As for the standard of CDMA2000, it is mainly accepted in US, Japan and Korea. Som teleeom enterprises, such a.s LG of Korea, adopt CDMA2000 in developing 3G. And Qualcomm Is its main technical supporter. TD-SCDMA is also one of the three major standards of 3G authorized by ITU. Datang Telecom Technology Co. Ltd. of China owns the independent intellectual property right of TD-SCDMA. Comparing with WCDMA arid CDMA2000, TD-SCDMA now is still in the research process. And no telecom carriers have said to adopt it. The lack of resources and teleeom carriers' supporting pushes TD-SCDMA into a disadvantageous position, Therefore, we may have doubts about the future of TD-SCDMA,How will it develop? The following article will give us a clear answer,
