If the mobile signal is not good, a cell phone jammer device may be installed. The purpose is to let everyone install broadband. Is this true? There are many people who are suspicious of this problem, and friends who live in the old city can observe a lot.
I don’t know if you have noticed that some rooms in the area where you live often have poor or no cell phone signals, but outdoor cell phone signals are very good.
Especially if the signal was very good before and can be used normally, but the mobile phone signal is not good or there is no signal recently, then it is possible that a mobile phone shielding device has been installed.
Why would anyone install a mobile phone shielding device? In some old towns, the broadband that can be installed is basically one or two, and other broadband cannot be accessed. For the sake of profit and sales performance, some crooked ideas may be made. Nowadays, 4G and 5G network speeds are fast. Data traffic alone can meet the needs of most people. No one wants to install broadband wifi. Even some people have unlimited mobile phone traffic, which is even more unnecessary. Install broadband.
Of course, in addition to the mobile phone shielding device that will affect the mobile signal, it is also very likely that the data signal amplifier is installed, which causes the data signal to be disordered and the mobile signal is not good.
In the old city, there are dense houses and insufficient data signal coverage. Some buildings have poor or no signal from mobile phones. In order to retain tenants, homeowners will install signal boosters. If there are too many signal boosters, data signals will be disordered , The mobile phone signal is poor.
For these areas where there is no signal booster, the data signal becomes worse, and even the signal cannot be connected to the Internet, or the network is very stuck. In this case, the network is robbed.
The above is the introduction of why the mobile phone shielding device is installed.
