3G的三大标准形成了三大技术阵营,在过去的两年里,它们之间展开了一轮白热化的竞争。没有完美无缺的技术,无论是WCDMA、CDMA2000,还是TD-SCDMA都需要进一步改进和发展。但不可否认的是,经过一轮搏杀之后,WCDMA由落后到领先,走到了3G商用化的前端。 WCDMA商用化推迟原因 两年前,3G在欧洲风起云涌。由于欧洲移动网以GSM为主,因此,欧洲运营商几乎都向着WCDMA方向发展。但在随后的一年多时间里,欧洲的运营商虽然在不断部署WCDMA网络,却迟迟推不出商用化服务。原因是多方面的,其中最主要的是电信网络泡沫的破灭。欧洲运营商支付了超过1200亿欧元竞拍3G牌照,导致背负巨额债务,没钱投入3G的网络建设,从而直接影响3G服务的如期推出。 经过两年的调整,欧洲运营商的债务压力已得到缓解,整个3G产业正在稳步复苏。在北美、亚洲和欧洲,一些WCDMA网络正在或即将进入商业使用。
The three major 3G standards form three major technology camps, and in the past two years there has been a heated competition between them. There is no perfect technology, whether it is WCDMA, CDMA2000, or TD-SCDMA need to be further improved and developed. But it is undeniable that, after a round of fighting, WCDMA from behind to the leading 3G commercialized front. WCDMA commercialization postponed two years ago, 3G surged in Europe. As the European mobile network to GSM-based, therefore, almost all European operators toward the WCDMA direction. However, in the ensuing more than a year, European operators have been pushing commercialization services despite continuous deployment of WCDMA networks. The reasons are many, the most important of which is the burst of telecom network bubble. European operators paid more than 120 billion euros auction 3G licenses, resulting in huge debt, no money into the 3G network construction, which directly affect the launch of 3G services on schedule. After two years of adjustment, the debt pressure of European operators has been eased and the entire 3G industry is recovering steadily. In North America, Asia and Europe, some WCDMA networks are or are about to enter commercial use.
