Prisons use wifi signal interceptors

Since wifi jammer can usually interfere with multiple frequency bands, the interference frequency bands are WiFi, CDMA, GSM, DCS, PCS, and 3G 4G, and all TX frequencies, so only machine interference can work perfectly with mobile phones and GPS, and combine the interference together. In addition, if the operator is not near the device, the WiFi interference device should be turned on and off, and the device can also be turned on or off using the remote control.
