地铁隧道WCDMA网络覆盖研究

Research on WCDMA Network Coverage of Metro Tunnel

主要介绍地铁隧道的WCDMA网络覆盖,首先论述地铁线路覆盖与一般室外宏基站及室内覆盖的区别,然后从网络覆盖信号强度要求、小区划分及小区间切换带的预留、LAC区划分3个方面进行详细的分析和论述,从而为地铁隧道的WCDMA网络覆盖提供参考。

This article mainly introduced how to cover metro tunnel with WCDMA radio network. Firstly,the difference in the coverage planning between the metro tunnel and the outdoor macro sites is provided. Then, from three major aspects of the signal strength requirements about network coverage, cell division and cell overlapping for hand off is analyzed and discussed. Thus it＇s as a reference to covers metro tunnel with WCDMA radio network in a later.
