How to jam a wifi network?

In addition to bandwidth, another reason that affects the WiFi of wireless networks is WiFi congestion. Just like a highway, when there are more cars, it will naturally slow down. If there are more WiFi in the same space (upstairs in your house, next door, neighbors...), the speed will inevitably slow down. The overlapping of adjacent channels will cause interference with each other. When two or more 802.11b transmitters operate in the same space, their signals must be attenuated to less than -50dBr and/or have a frequency separation of at least 22 MHz to prevent interference. In fact, the DSSS algorithm uses a 20 MHz bandwidth when transmitting data, and the remaining 2 MHz gap is used as a guard band to attenuate electromagnetic waves at the edge of the frequency used to avoid interference with adjacent channels. WiFi jammers are the most affected.
