近年來，手機信號屏蔽器應用越來越廣泛，雖然應用該種設備實現了在特定場所禁打手機的目的，但同時也給移動通信系統帶來了嚴重的干擾。為了規范手機信號屏蔽器的使用，定量研究出手機信號屏蔽器的有效屏蔽范圍，以及屏蔽范圍之外對移動通信系統的影響，從手機信號屏蔽器的工作原理以及信號在傳播中的損耗研究出發，依據通信行業有關標準及無線傳播模型對手機信號屏蔽器進行了研究。最后通過對比分析計算數據與實際測量數據，驗證了該模型計算方法是正確可行的。

Abstract:

?In recent years, the mobile phone signal blockers are extensively used, although the using of these equipments in particular places can restrict cell phone，but meanwhile bring serious interference to mobile communication systems. In order to regulate the use of mobile phone signal blockers, quantitative research the device’s effective shielding range and the influence to mobile communication systems, this paper began from the working principle of mobile phone signal blockers and the propagation losses during the signal transmission, and then gave the study of mobile phone signal blockers according to the relevant standards of the communications industry and wireless propagation models. Finally though comparing and analyzing the calculation data and the measurement data, verified the model calculation method which is correct and feasible.
