1.概述3G网络的基础传输网络,是目前运营商网络准备的重点。对于3G业务网络,由于其底层协议与2G的区别,传输接口与2G的区别,以及网络组网与2G的区别,对基础传输网络的要求也不一样。本文主要从WCDMA传输接口、传送网技术选择和网络演进三个方面探讨烽火通信3G传输网络解决方案。WCDMA网络主要由两个部分组
1. Overview The basic transmission network of 3G network is the key point of the current network preparation for operators. For the 3G service network, the requirements for the basic transmission network are different because of the difference between the underlying protocol and 2G, the difference between the transmission interface and 2G, and the difference between the network connection and 2G. This article mainly discusses the solution of 3G transmission network of beacon communication from three aspects of WCDMA transmission interface, transmission network technology selection and network evolution. WCDMA network mainly consists of two parts group
