考场信号屏蔽器可以屏蔽哪些信号？

考场信号屏蔽器可以屏蔽哪些信号？

不管是国考还是英语四六级，都需要用到考场信号屏蔽器。但是，很多人不明白考场信号屏蔽器的工作原理。甚至不太清楚，考场信号屏蔽器可以屏蔽哪些信号。今天，小编就来给大家说说，关于考场信号屏蔽器的那些事。
现在市面上常见的考场信号屏蔽器基本上可以屏蔽市面上所有运营商的信号。其中还包括了比较生僻的 VIFI，已杜绝任何一个考生钻空子的机会。此外，根据信号的频段，考场信号屏蔽屏蔽的信号也有所不同。现在科技越来越发达，4G 信号的屏蔽基本上所有的考场信号屏蔽器都能够屏蔽了。不过，科技发展的速度太快了。现在慢慢的开启 5G 时代了。这些考场信号屏蔽器，也要跟着升级。不过，很多公司的科技水平还跟不上。
在行业内，目前支持屏蔽 5G 信号的公司不多，北京神州明达公司就有几款支持屏蔽 5G 信号的考场信号屏蔽器。随着科学的发展，考场信号屏蔽器的技术不更新就会被淘汰，这已经成了必然。像这样的考场信号屏蔽器一般都是用来屏蔽手机信号。在考场附近使用手机也会受到信号干扰。不过，现在的考场信号屏蔽器都有上行信号屏蔽，对普通手机信号的干扰已经比较少了。通常，它们主要是用来干扰发射特定信号的手机。目前市场发展的前景很好，像这样的考场信号屏蔽器也越做越好，所以，需要购买的学校也不需要担心。
