While performing a manual scan of your environment using a spectrum analyzer on a laptop computer, you notice a signal in the real time FFT view. The signal is characterized by having peak power centered on channel 11 with an approximate width of 20 MHz at its peak. The signal widens to approximately 40 MHz after it has weakened by about 30 dB.

What kind of signal is displayed in the spectrum analyzer?

Looks like someone's trying to hack the WiFi with their toaster oven or something. Where's my tinfoil hat when I need it?

I'm leaning towards it being an 802.11a AP operating normally in 5 GHz.

I believe it could be a low-power wideband RF attack causing interference.

Wait, is this a trick question? A frequency hopping jammer in 5 GHz? I'm calling shenanigans on this one!

Nah, 5 GHz band with a signal that wide? Gotta be an 802.11a AP, no doubt about it.

Hold up, 40 MHz wide after a 30 dB drop? Sounds like a wideband attack to me, better call the cyber police!

Hmm, 20 MHz wide signal in the 2.4 GHz band, must be an 802.11g AP. Easy peasy!
