Channel Devices
The bottom part of the Spectrum-WiFi Summary is Channel Devices, which lists the number
of APs, stations, and/or VoFi phones that have been detected on channel in the selected 802.11
radio band. Similar to the AP List above, this part of the screen is devoted to the display of
WiFi data only. You must have an AirMagnet-supported external wireless network adapter in
order for AirMagnet Spectrum XT to capture and display such data. See Figure 3-5.
Figure 3-5: WiFi devices listed by channel
The Channel Devices pane only displays channels on which WiFi devices are detected. If you notice
certain channels missing from this section, it means that no WiFi devices have been detected on
those channels. Also, the channels shown here vary depending on the option selected from the Band
menu in the toolbar. Users can click the Device Pattern tab to view a sample image of the detected
spectrum pattern of devices detected. See “Device Pattern” on page 108.
Graph Window
The right-hand side of the screen is the graph window, which can display up to three graphs
vertically at the same time even though the user do have the option to display one or two
graphs using the Settings drop-down list menu. By default, the graph window displays the
Real Time FFT, Spectrum Density, and AP Signal Strength graphs, but the user can change the
content of the window using options in the Easy View list menu on the toolbar or by using
options in the Spectrum Graphs or WiFi Graphs. See Figures 3-6 and 3-7.
