WCdMA,HSPA+3G到4Gfdd-lte需要重新布网建站吗？ h
设备商的大神，来解析下。

不一定， 可以共享一些module的。。
选爱立信的就行啦 硬件基本上不用动啦 真正做到多模！
看情况而定
基本都在搞多模 平滑过渡的了
Ericsson Evo Controller beats Huawei and ZTE controller products
Evo Controller 8200 has recently reached General Availability (GA) and it is clearly unbeatable on the controller market. In our recent analysis comparing EvoC 8200, Huawei’s BSC6900 and ZTE’s ZXUR 9000 (though questioned multimode capability) it can be concluded that Evo Controller 8200 has significant competitive advantages in terms of capacity, flexibility and cost of ownership.
First of all, Alcatel-Lucent and NSN do not have a multimode controller yet, despite the vendors’ claims. The only competing multimode controllers currently available are from Huawei and ZTE, and even ZTE’s multimode existence is being questioned by customers and external analysts 。
所以是不需要的，HW ZTE都有这样的多模设备的

基站控制器 真正意义上的多模 也就是8200吧
基站方面爱立信的多模基带都商用了 别家好像还没有呢

G到W要重新建设，W到LTE要重新建设。只有机房塔桅传输可以共用
严格来说，DUS41只是multistandard single mode，也就是要么跑GSM，要么跑LTE(FDD或TDD都行)，还不能同时跑多标准，也不支持WCDMA。mixed mode digital要等DUS42…
最好别在建站了
从WCDMA升级到HSPA+不用重新建站，只要更换相应板卡就可以。不过4G的LTE需要重新建网换设备，从WCDMA 到 LTE不能平滑过渡。但中国电信的CDMA2000到LTE是可以平滑过渡的。原因不懂，但以前听培训课上的老师说的，就记住结论了~
