Question
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?
Options
- AA frequency hopping device is being used as a signal jammer in 5 GHz
- BA low-power wideband RF attack is in progress in 2.4 GHz, causing significant 802.11 interference
- CAn 802.11g AP operating normally in 2.4 GHz
- DAn 802.11a AP operating normally in 5 GHz
