A cell phone jammer (or cell phone jammer) is a device used to interrupt the communication signal between a cell phone and its base station. It deliberately keeps the phone out of range. The signal jammer is actually used to turn off the phone’s Wi-Fi, Bluetooth, camera, and call/message functions.
For example, you often see cell phone jammers in entertainment venues where silence is a priority. Recital or theater. You can also find them in offices where managers don’t want any interruptions during important meetings.
Mobile phone signal jammers are also very effective in the home. Parents can easily divert the attention of their loved ones from their mobile phones.
Creating a cell phone jammer can be very laborious, especially if you don’t like electronics. Or, you can buy a cell phone jammer so you don’t have to go through the complicated things of building a DIY.
