目前,中国电信已经开始在江苏、上海、云南、四川、福建等省市陆续启动CDMA放号。中国电信在各地C网割接运行顺利,老用户平稳过渡,每日新入网用户也出现连续增长。与TD-SCDMA、WCDMA相比,CDMA技术最突出的优势表现在平滑演进方面:cdma1x到EV-DO Rev.0以及EV-DO Rev.0到EV-DO Rev.A的平滑演进特性,可实现CDMA网络的快速升级,使运营商在短时间内完成全网覆盖成为可能,从而有利于运营商降低运营成本。中国电信业重组后,运营商对最终用户的争夺战必将愈发激烈,因此有分析指出,中国电信除应该尽早筹划1X网络向EV-DO Rev.A网络的平滑演进以外,在EV-DO 3G网络发展成熟后,还可以考虑在适当的时机将网络升级到EV-DO Rev.B。
At present, China Telecom has started to launch CDMA radios successively in Jiangsu, Shanghai, Yunnan, Sichuan, Fujian and other provinces and cities. China Telecom C cut off around the smooth operation of the smooth transition of the old user, the daily new network users also showed a continuous growth. The most prominent advantages of CDMA technology over TD-SCDMA and WCDMA are the smooth evolution of cdma1x to EV-DO Rev.0 and EV-DO Rev.0 to EV-DO Rev. A, The rapid upgrade of CDMA network makes it possible for operators to complete network coverage in a short period of time, which helps operators reduce operating costs. After the reorganization of China’s telecom industry, operators will be fierce battles for end-users, so some analysts pointed out that China Telecom should plan as soon as possible 1X network to EV-DO Rev.A network smooth evolution, EV-DO After the 3G network is mature, you may also consider upgrading the network to EV-DO Rev.B. at the appropriate time.
