3G基站传输组网研究

Research on 3G base station transmission networking

文章首先介绍了3G基站常规组网方式:星型组网、链型组网、树型组网、混合组网、级联RRU组网,然后探讨了3G/2G共传输通道组网方式:3G共用2G基站传输通道组网2、G共用3G基站传输通道组网,并分析了各自组网方式的基本原理、使用场合、拓扑结构和优缺点。

This paper firstly introduces the conventional networking methods： star-shaped networking;chain-shaped networking,tree-shaped networking,hybrid networking and cascade RRU networking.Then,it expounds the networking of 3G/2G sharing the transmission channel,3G sharing 2G base station transmission channel and 2G sharing 3G base station transmission channel.It also analyzes the basic principles,application environment,topology and the advantages and disadvantages.
