Have you ever heard people around you complain about similar reports again and again in life? The first thing they think of is that the network that telecom operators have worked hard to build is still not good enough or faster. In general, in this case, as long as our mobile phones can have data signals connected to the base station smoothly, the Internet speed will definitely not be bad.
Mobile phones with good data signal performance can change between Wi-Fi and 5G networks at will, and will automatically restore to 5G when the data signal is relatively poor; on the contrary, when the mobile phone cannot achieve efficient arbitrary switching between Wi-Fi or 5G, "slow speed" in the Wi-Fi environment may appear.
If you find that the mobile signal in this area is good, it may be that the network operator specifically covers the indoor signal; on the contrary, if the data signal is poor, it means that the wireless signal comes from the outdoor base station and the indoor coverage effect is not ideal. It is also possible that the Internet speed will naturally slow down when there are too many people using the network, which also explains why crowded working roads are usually slower, and the network environment immediately becomes better during the quiet night. In addition, there are places where cell phone signal jammers are installed. When entering this area, the mobile signal will disappear. This place is very likely to be installed with mobile phone signal jammers. But it also shows that such places are likely to be very important areas, and it is necessary to prevent the network from leaking secrets.
Why install a mobile phone signal blocker? Some mobile phone applications have hidden functions, such as the spy function. After the application is activated, it will automatically expose the location. It seems that an application has been closed through its own "exit" function, but in fact it still stays in the background of the mobile phone and becomes a "nail household". So in order to prevent such things from happening, many important areas will install mobile phone signal blockers.
In the process, the mobile phone will have full data signals. This is because the data signal is really good, but our mobile phone network speed will be very unstable. Most of these situations occur around schools. Generally, the mobile signal disappears or there is a data signal but no signal. In this case, the school has turned on the mobile phone signal blocker. When the school installed the mobile phone signal blocker, it was to prevent students from secretly playing with their mobile phones and cheating in exams. Since the mobile phone signal blocker was installed, the students' learning habits have been greatly improved. In addition, if the school installs a signal blocking device that affects you, I hope you can understand in the future. After all, everything is for the future of the children and the country. You can report to the school and ask the school to adjust the power of the signal blocking device to clear the surrounding signal.
