What is the gray on Spectrum Analyzer

Attached the SA from a customer radio that is frequently dropping session and staying dropped for hours at a time. The SA has been running for about 20 minutes at this point and still hasn’t ID’s any of the sectors on the tower though all three are clearly visible on the spectrum graph.

Anyway, customer radio sees the AP at about -72 and the graph there shows about the same but what is the meaning of the huge gray areas ?

Hello Sir,

the “Gray color means that the signal from the interference source has been captured at least once, but any new frames weren’t captured after for a long time.” So, now that area is no longer affected by interference at the moment.
