After starting the Cell Phone Blocker At Schools device, sometimes we will find a strange thing, since the mobile phone signal jammer is already working, theoretically the mobile phone cannot receive the signal within the range of the signal shielding, but why some mobile phones still Can you show the signal? The following editor will briefly explain to you why some mobile phones still display the problem of signal after starting cell phone jammer . First of all, according to the theoretical shielding effect, when the mobile phone signal jammer device is working, it is impossible to display a signal on the mobile phone. So in this case, there are two possibilities for the signal on the mobile phone. One is that the mobile phone can still get through within the signal coverage of the mobile phone signal jammer.
If the mobile phone can be connected, it means that the shielding area has not achieved effective shielding, and there are shielding leaks and blind spots, which in turn means that the Cell Phone Blocker At Schools product you are currently working on cannot meet your on-site shielding requirements; However, the mobile phone cannot be connected. If this is the case, it means that the mobile phone is currently in a critical state, which generally occurs on mobile phones with strong anti-interference and high sensitivity. We have been focusing on the research and development, production, sales and engineering installation of mobile phone jammers for more than 10 years. We are one of the few most professional signal jammer manufacturers in China.
