近年來(lái)，手機(jī)信號(hào)屏蔽器應(yīng)用越來(lái)越廣泛，雖然應(yīng)用該種設(shè)備實(shí)現(xiàn)了在特定場(chǎng)所禁打手機(jī)的目的，但同時(shí)也給移動(dòng)通信系統(tǒng)帶來(lái)了嚴(yán)重的干擾。為了規(guī)范手機(jī)信號(hào)屏蔽器的使用，定量研究出手機(jī)信號(hào)屏蔽器的有效屏蔽范圍，以及屏蔽范圍之外對(duì)移動(dòng)通信系統(tǒng)的影響，從手機(jī)信號(hào)屏蔽器的工作原理以及信號(hào)在傳播中的損耗研究出發(fā)，依據(jù)通信行業(yè)有關(guān)標(biāo)準(zhǔn)及無(wú)線傳播模型對(duì)手機(jī)信號(hào)屏蔽器進(jìn)行了研究。最后通過(guò)對(duì)比分析計(jì)算數(shù)據(jù)與實(shí)際測(cè)量數(shù)據(jù)，驗(yàn)證了該模型計(jì)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.
