摘 要:针对实际无线环境中的穿透损耗进行研究,对典型、普遍意义的楼宇室内外进行WCDMA和GSM信号强度(Ec)及信号质量(Ec/Io)进行测试,并得出了不同情况下综合穿透损耗和净穿透损耗的数值,可作为移动通信系统室内外覆盖系统设计的参考。一些结论同样可用于其他3G系统和4G系统。Penetration loss of wireless environment has been studied in this paper. The signal strength (Ec) and signal quality (Ec/Io) of WCDMA and GSM networks in indoor and outdoor scenes of buildings had been tested. The tested data with the comprehen-sive penetration loss and net penetration loss of differ-ent circumstances could be used as reference of mo-bile communication system indoor and outdoor signal coverage system construction. Some conclusions in this paper also could be applied on other 3G/4G system.
