GSM/WCDMA网络共基站建设分析

3G网络牌照发放日益临近，从充分利用现有网络资源角度出发，GSM网络运营商宜采取GSM／WCDMA网络共基站建设。本文从3G网络规划的覆盖要求分析了3G／2G基站共站址的可行性。然后，对系统干扰进行了分析，得出隔离度要求并计算了隔离距离，给出了工程改造的隔离建议；最后，从机房和天面两个方面，对共基站配套改造建设进行了分析。

Analysis of GSM/WCDMA Networks Construction Based on Sharing Station Address

To fully use the resources of the existent networks, operators with GSM networks should construct 3G networks based on sharing station address. In this paper, we first analyze the availability of sharing station address according to the requirement of networks coverage. Then we analyze the interference between the GSM and WCDMA systems, and give the disturb distance for engineering requirement between the antennas of the two systems. Last we supply some suggestions on reconstruction the sharing equipments in the station address, such as machinery room and tower for antennas.
