摘要
从技术角度对地铁内综合无线分布系统进行多信号频率研究及干扰分析,通过对系统核心器件综合合路平台、高功率线性功放的研究,实现系统最佳覆盖效果,并通过地铁1、2号线GSM、CDMA覆盖工程实例得以验证。
Mobile communication service and urban rail transit developed very fast in recent years, and it is a trend to adopt mobile communication into metro. This paper makes a study of integrated radio distribution system （ IRDS）, the multi - signal frequency and interference analysis from technical aspects, discusses the core components of IRDS, such as POI, HPA and antenna distribution system. Finally, the paper introduces the test of IRDS by GSM and CDMA in Shanghai Metro Linel and Line 2.
