As the number of mobile users increases, mobile phones need to be disabled in certain places, and their ringtones will be disruptive. These include places of worship, lecture rooms, hospitals, concert halls, meeting rooms, prisons, etc. cell phone jammer are very effective in classified conference rooms where important information can be leaked from one room to the outside without knowing anyone else. Signal blockers can be very effective in breaking communication between prisoners in prisons. Wardens no longer have to worry about cell phone inmates.
Over the past two decades, we’ve seen a surge in the number of mobile phone users. This has increased the need for more efficient and reliable signal shields in civilized societies. Mobile jamming devices are becoming civilian products rather than electronic warfare devices.
A mobile phone communicates with its service network through a base station. As the phone user drives down the street, the signal switches from one base station to another.
Different communication systems use different frequencies so that everyone is at peace.
The basic principle of cell phone jamming devices is to emit the same radio frequency signals as cell phones. Because of the same frequency, the phone can’t tell which signal is the regular base station signal, thus achieving “interference”. As long as there is a machine with the same frequency as the phone, it makes a lot of “noise” when the base station tries to connect to the phone. You will find that the signal from the phone is unrecognized, so you will refuse to communicate with the phone.
Whether it’s a theater, an educational institution, a coffee shop, a restaurant, an office, or anywhere else, almost everyone has access to a cell phone. These days, people spend most of their time on their phones instead of spending time with their families or focusing on organizational goals. While mobile phones can help you in many ways, they also distract many people from their lives. This is where the cellular network signal jammer enters the game. Jamming is the act of blocking something, so mobile jamming is preventing network signals from reaching your mobile phone, thereby denying access to the Internet, sending text messages or making phone calls.
