WIFI jammer transmit on the same frequency as the signal to be jammed. However, if the jammer sends a significantly stronger signal, it renders the original signal unusable -- making communication more difficult or impossible.
In a WLAN, this means that the exchange of packets only works to a limited extent or does not work at all, and the actual data flow can no longer be properly grouped together. This can be a critical issue for devices performing safety-related tasks. There are more and more wireless wifi coverage projects, especially large and medium-sized wireless coverage, which involve practical problems such as channel planning, co-channel interference, and network delay. Wireless network co-frequency interference will cause network packet loss and delay, resulting in poor wireless network quality and slow network speed. Because the two APs work at the same frequency and interfere with each other, data will be sent frequently and repeatedly. The more frequent, the more serious the co-channel interference.
However, Wireless wifi jammer is perfectly normal in radio technology. In the early 20th century, when the number of transmitters greatly increased, poorly shielded machines caused interference with radio signals. But even today, WLAN networks that transmit close to each other on the same radio channel sometimes interfere with each other. However, the problem was not so severe that all data traffic stopped.
