In some occasions that need to restrict the use of mobile phones, installing and using signal jammers is a relatively routine and feasible implementation method, so some customers have questions: signal jammers have a shielding effect on mobile phone signals, so for mobile phones Do the various APPs of the company also have a shielding effect?
In fact, in the actual application scenario, when the mobile phone is within the effective coverage of the signal jammer, the most intuitive feeling for mobile phone users is that the mobile phone will be offline, that is, there is no signal displayed on the mobile phone. At that time, there is no connection and communication between the mobile phone and the base station. If you make a call at this time, you will find that the mobile phone cannot be dialed out at all, and of course there will be no external calls. Dial to this mobile phone. At the same time, it will also be found that the state of many APP software on the mobile phone will be somewhat different compared with the past. For example, chat and communication software will prompt that it is offline. When viewing audio, video and other playback software, the content of audio and video programs on demand will not be played. When browsing news websites, you will find that news items cannot be refreshed to update content and so on.
As for the question mentioned at the beginning: Will the signal jammer block the APP application software? This depends on how to understand the application of the software. Because the signal jammer actually shields the signal of the mobile phone, making the mobile phone lose the ability to communicate with the outside world. The shielding function mentioned here refers to signal shielding. The various APP software on the mobile phone can actually be opened and run normally, but due to the loss of real-time networking communication capabilities, although the software can run normally, it cannot update data or communicate with the outside world. Some audio and video software can still play local files stored on the mobile phone even when the signal is lost.
