reading the spectrum analysis

Question

Not familiar with the spectrum analysis, looking for information on what it is telling me.

The cumulative view tends to be more useful than the instantaneous view.

From my look at your cumulative view, it looks like you've got a lot of nearby 2.4GHz activity in the channel 1 and channel 8 ish region, while the area right below channel 6 tends to be least used.

The graph shows a heat map of what receive strengths are most often perceived at each frequency. A Ruckus AP generally has a noise floor on the order of -95 dbm or lower (e.g. more negative), so if you powered up your Ruckus in a completely clean environment you'd expect to see one big red line at -100 or so.

Hi Jbrown,

It is showing the view of received signal power across the band and the color coded using signal power (-110 to -20dbm). Week signal is the blue ==> Red .

It also shows that Cumulative Distribution of received power across the band . <20% blue ==> 80% Week signal (Red)
