Shorter time to update network because for WCDMA and TD-SCDMA updating from GSM , it almost means reconstruction network which may takes 2 and 3 years respectively. But for CDMA2000 update only need several months that has an advantage of 1.5 years in advance.

Product feature:

1.Shorter time to update network because for WCDMA and TD-SCDMA updating from GSM , it almost means reconstruction network which may takes 2 and 3 years respectively. But for CDMA2000 update only need several months that has an advantage of 1.5 years in advance.

2.Low cost, CDMA upgrading cost is only 1/3 of the reconstruction cost.

3.Better for service optimization protect customers’ rights. Users hope their network updates gradually so they do not have to replace their phones all the time. CDMA will backward compatible to old mobile phones when updating networks. Every section in CDMA2000 can covers 120 calls at the same time which is three-times compared to current system.
