Blocking WiFi signals in a room can be achieved using a WiFi jammer.
WiFi jammers work by emitting radio signals on the same frequency as WiFi routers and other wireless devices. This interference disrupts the wireless signals, making it difficult or impossible for devices to connect to the network. wifi jammer can be purchased online.
There are also other methods for blocking WiFi signals in a room. One method is to use signal blocking materials such as metal or foil to block the wireless signals. This can be achieved by lining the walls, ceiling, and floor of the room with a signal blocking material. However, this method can also interfere with other wireless signals in the surrounding area.
Another method for blocking WiFi signals in a room is to use a wireless access point that is specifically designed to block signals. These devices can be configured to only allow specific devices to connect to the network and can block all other devices. This method is more effective and legal than using WiFi jammers.
