考场信号屏蔽器有哪些使用误区

2019-04-12 2281 神州明达-小明

考场信号屏蔽器有哪些使用误区？
考场保驾护航缺不了神器考场信号屏蔽器。听上去就很厉害的样子，不过，这个神器并不是想象总的万能。那么，考场信号屏蔽器有哪些使用误区？首先我们应该了解，考场信号屏蔽器的使用范围，通常以直线距离来计算的话，大部分的考场信号屏蔽器能够屏蔽的范围是五十米左右。如果是以教室大小计算，那么，一般是一间教室的范围。很多人之所以会误解，以为考场有了信号屏蔽器就万能，那也是对这种仪器的原理不了解。

它们主要是通过电磁来干扰来干扰手机的信号，以达到手机和手机之间不能沟通的目的。但是，不同的信号屏蔽器能够作用的范围不同。所以认为安装了信号屏蔽器就可以杜绝所有的舞弊现象这也是不正确的。安装信号屏蔽器，还需要根据周围的环境选择。比如，如果附近有信号基站，或者有扩大器。那么，这个时候往往在一件一百平左右的教室里安装一台考场信号屏蔽器是不够的。因为不管是基站还是扩大器都会干扰到信号屏蔽器的正常工作。按照正确的方式，安装信号屏蔽器的时候应该尽可能的离基站或者扩大器远点。当然，这也不是必然。比如北京神州明达现在就生产了一种能够对付扩大器的产品。用这样的产品的话，效果就比普通的考场信号屏蔽器的效果更好，也不需要担心不是专业人士，不知道应该怎么安装了。
