Table 3-3 briefly describes the data displayed in this part of the screen.
When the user selects a channel from the Channel Summary, that channel’s portion of the wireless
spectrum is highlighted in the charts displayed to the right. This makes it easy to identify exactly
where a device is appearing in charts like the Spread Spectrogram, among others.
Device List
Below Channel Summary is the Device List. It shows all the Devices (WiFi and non-WiFi) that
the application has detected in the network. The Device List contains two tabs that categorize
devices based on their wireless characteristics; standard 802.11 Wi-Fi devices are displayed on
their own tab, and non-802.11 devices on a second one.
When viewing the 802.11 devices portion, the drop-down menu across the top of the pane can
be used to change the manner in which the devices are displayed, either by SSID or by
Channel. See Figure 3-4.
Figure 3-4: Choosing an AP List option
You can project signal strengths of any APs over the Spectrum Density graph by selecting
them (checking the corresponding check boxes in the AP List). Signal strengths of the
corresponding APs will appear in the graph in the form of color-coded curves.
