it affects all those channels. Similarly,if a channel-hoppingdevice uses all channels within a frequency band, it is
counted as a device on all channels in that band.
Whenyou hover the mouse over any part of the chart, a tooltip shows the numbers of the device type currently
using that channel.The example in Figure 219 shows that t he spectrummonit or can detect 42 APs on channel5.

Parameter Description
Band Radio band displayed in this graph.
Forspectrum moni tor radios using the 5 GHz radio band, cli ck the Banddr op-down list and select 5
GHzupper,5GHz middle or 5Ghz low er todi splaydata for that portion of the 5Ghzradio band. This
parameteri s not configurable for graphs created by hybrid APs or spectrum monitor radios that use
the2.4 GHz radio band.
Channel Numbering Forspectrum moni torsusing the5 GHz radio band, select either 20 MHz or 40 MHz channel
numbering to identifya channel numberingscheme for the graph.
NOTE:Thi s parameter is not configurable for graphs created by hybrid APs or spectrum moni tor
radiosthat use the 2.4 GHz radio band. A hybrid AP on a 20 MHz channel sees 40MHz Wi -Fi dataas
non-Wi-Fi data.
Channel Range Forgraphs created by spectrum monitors, specify a channel range to determine which channels
appeari n thisgraph. Clickthe first drop-down list to select the lowest channel in the range, then
click thesecond drop-down l istto select the highest channel to appear in the graph.
Bydefault, this graph displays all channels within the spectrum monitor’s radio band.
NOTE:Thi s parameter is not configurable for graphs created by hybrid APs.
Show Thisgraph can show data for up tofive different device types. To show how many devices of a
specifictype are sending a signal on the selected channel range, cli ckthe show checkbox by that
device, thencl ick thedevice drop-dow n list and selectone of the followi ng device types.
