A security researcher has demonstrated that jamming WiFi, Bluetooth, and Zigbee networks is not difficult to perform but, most importantly, also not as costly as one might think.In my security nerd heart of hearts, I want frequency hopping WiFi. But you'd need a wider band of frequency than the FCC would give up.
According to Mathy Vanhoef, a PhD student at KU Leuven (Belgium), it can easily be done by using a Wi-Fi $15 dongle bought off Amazon, a Raspberry Pi board, and an amplifier that will broaden the range of the attack to some 120 meters.
The attack would hit all devices within range that operate in the 2.4 and 5 Ghz bands.
Damn Fed.Gov, bogarting all the frequencies ...
