The spectrum link displays the following: l Device list-The device list display consists of a device summary table and channel information for active non Wi-Fi devices currently seen by a spectrum monitor or a hybrid W-IAP radio. l Channel Utilization and Monitoring-This chart provides an overview of channel quality across the spectrum. It shows channel utilization information such as channel quality, availability, and utilization metrics as seen by a spectrum monitor for the 2.4 GHz and 5 GHz radio bands. The first bar for each channel represents the percentage of airtime used by non-Wi-Fi interference and Wi-Fi devices. The second bar indicates the channel quality. A higher percentage value indicates better quality. l Channel Details-When you move your mouse over a channel, the channel details or the summary of the 2.4 GHz and 5 GHz channels as detected by a spectrum monitor are displayed. You can view the aggregate data for each channel seen by the spectrum monitor radio, including the maximum W-IAP power, interference, and the Signal-to-Noise-plus-Interference Ratio (SNIR). Spectrum monitors display spectrum analysis data seen on all channels in the selected band, and hybrid W-IAPs display data from the single channel that they are monitoring. For more information on spectrum monitoring, see Spectrum Monitor on page 341. Alerts Alerts are generated when a user encounters problems while accessing or connecting to a network.
