| 摘 要： | 从IS-95演进到1xRTT是CDMA网络向3G迈出的第一步,1xRTT的优点包括数据速度大幅提高、话音容量显著增加、永远在线、手机电池寿命大大延长、后向兼容性以及话音/数据共享载波等。率先部署CDMA2000 1xRTT的北美CDMA运营商贝尔移动公司从自身角度对CDMA网络的演进进行了评述,认为部署CD-MA2000 1xRTT的时机已经来临。

| Abstract: | The evolution from IS -95to1xRTT is the first step from CDMA to3G.The ad vantages of1xRTT include great improve ment of data speed,obvious increase of voice capacity,permanent on-line,prolong ing of mobile battery,reverse compatibility and voice /data sharing carrier.The CDMA operator in North America,Bell Mobile,who took the lead in imple-menting CD MA20001xRTT,commented on the evolu tion of CDMA network from its point of view.It is thought that it is time to im plement CDMA20001xRTT. |
