通信铁塔共享改造与系统干扰的分析

Analysis of Communications Tower Sharing Transformation and System Interference

在今年的网络建设中,移动、电信和联通在基站设施、铁塔和传输线路中广泛的开展了共建共享工作。共建共享工作的一个最大特点是几种不同制式的移动通信系统共同使用一套基础设施、铁塔以及传输线路。在共享方案的制定和实施过程中,要充分考虑不同制式通信系统之间的天线隔离度和干扰协调。解决不同系统的干扰,主要是对天线系统中的铁塔进行共享改造,以实现其支撑的天线保持有效的隔离度,避免不同频率之间的信号产生干扰。

In this year,a large scale of network construction,including infrastructure of BS,iron towers and transmission network,are co-headed by the three local telecom operators,namely China Mobile,China Telecom and China Unicom. One of the most important characteristics of this collaboration is that the infrastructure will be shared by several wireless systems with different standards. Thus,the consideration of both the distances of antennas and the coordination of interferences between different wireless systems ...
