All-IP Hardware Platform

According to network developing trend

By means of all-IP platform, iBSC can offer better PS services,

can easily realize IP Abis and IP Gb interface

Separation of User Plane and Control Plane

All-IP hardware is universal for ZXG CN, ZXWN RNC

(WCDMA) and ZXTR RNC (TD-SCDMA)
