WIFI signal shielding may occur when using WIFI. Do you know how and how this shielding can be created? Let's find out about this using the wifi jammer manufacturer's editor:
1) Brute force attack: Generate interference in the entire frequency band of the target frequency band (e.g. the 5G frequency band you mentioned). The greater the interference, the lower the signal-to-noise ratio. If the signal-to-noise ratio is lower than the small signal-to-noise ratio required for demodulation on the physical layer, demodulation cannot be achieved.
2) First, monitor the WiFi channel. Every time the router sends a signal, an interference signal is superimposed and the terminal cannot search for the router, which is equivalent to shielding the router. Or if the terminal wants to send data or interfere, it is impossible to communicate successfully.
3) Attack by protocol vulnerabilities.
