手机屏蔽器屏蔽范围及对通信系统影响的计算

近年来，手机信号屏蔽器应用越来越广泛，虽然应用该种设备实现了在特定场所禁打手机的目的，但同时也给移动通信系统带来了严重的干扰。为了规范手机信号屏蔽器的使用，定量研究出手机信号屏蔽器的有效屏蔽范围，以及屏蔽范围之外对移动通信系统的影响，从手机信号屏蔽器的工作原理以及信号在传播中的损耗研究出发，依据通信行业有关标准及无线传播模型对手机信号屏蔽器进行了研究。最后通过对比分析计算数据与实际测量数据，验证了该模型计算方法是正确可行的。

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.
