Channel Utilization Graphs and Information

Searching for a way to show how a channel is utilized for all connected SonicPoints resulted in channel utilization graphs:

Two color bars are displayed for each channel. The number on the top of each color bar indicates the number of SonicWall access points that detects the particular issue in that channel. SonicWall access points complete an IDS scan on all available channels upon boot-up, and RF Analysis analyzes these scan results to identify possible issues for each channel.

For example: If 10 SonicWall access points are connected, and 6 of these decide that channel 11 is overloaded, the number on the top of purple color bar is 6; if 8 SonicWall access points decide that channel 6 is highly interfered, the number on the top of the cyan color bar is 8. Zero is shown for channels no issues.

Channels 12, 13, 14 are shown, but in some countries these channels are not used. These channels are still monitored, however, because it is possible for a wireless cracker to set up a wireless jammer in channel 12, 13, or 14 to launch a denial-of-service attack to lower channels.
