The development of smartphone wireless networks plays an important role in increasing the speed of development. Mobile phones can solve network problems, and mobile phones play an increasingly important role in people's lives, mobile communications, and mobile Internet. Because of this, it caused a lot of problems. Especially in the home network, children are addicted to the Internet mainly because of the WIFI network. Therefore, many families gradually began to install wifi jammer to block the Internet and control the time of children's Internet access.
The simplest wifi Bluetooth jammer can be any powerful transmitter in the 2.4GHz area. A slightly modified microwave will work perfectly. Unmodified microwave ovens are already a major source of interference to 2.4Ghz Bluetooth and WiFi communications when in use. Remove more shielding and do some tweaking, and you have a very illegal, dangerous device that makes 2.4GHz radios very unpleasant.
You can also spoof control traffic for wireless networks, such as the common wifi de-auth attack, which spoofs commands from routers and clients to trick them into disconnecting from each other. Similar protocol attacks can block traffic very effectively. Much less dangerous.
