中国的3G 标准本来就有点乱,TD-SCDMA、WCDMA 和 CDMA2000三种标准就让众多服务提供商无所适从。但如今,业界人士又不得不次面对 CDMA2000也有点乱的局面,对于采用 CDMA2000 1X、CDMA20001XEV-DO 以及 CDMA2000 1XEV-DV 三种技术目前是众说纷纭。CDMA2000 1X EV-DO 和 CDMA2000 1X EV-DV 同属 CDMA2000 1X EV 技术。该技术的空中接口标准是对现有 CDMA2000 1x 的一个扩展,以支持至少2Mb/s 的高
China’s 3G standard has always been a bit chaotic, TD-SCDMA, WCDMA and CDMA2000 standards allow many service providers know what to do. But nowadays, the industry people have to deal with CDMA2000 again and again have a bit chaotic situation, for the use of CDMA2000 1X, CDMA20001XEV-DO and CDMA2000 1XEV-DV three technologies are currently controversial. CDMA2000 1X EV-DO and CDMA2000 1X EV-DV are both CDMA2000 1X EV technologies. The air interface standard for this technology is an extension to the existing CDMA2000 1x to support high at least 2Mb / s
