Back in 2007, Metageek sent me one of their Layer-1 2.4 GHz probes to play around with. So far I mostly used it for Wi-Fi network analysis. But the 2.4 GHz band is also used by other technologies such as Bluetooth. Unlike Wi-Fi with its 20/40 MHz channels, Bluetooth only uses 1 MHz chunks and performs frequency hopping over the full 80 MHz of the band to keep interference with Wi-Fi and other technologies using the band to a minimum. So far the theory. How it looks like in practice can be seen on the screenshot on the left (click opn the picture to enlarge). Thanks to Metageek, your hardware and software keeps coming in handy!
