Viewing RF Capacity

AirWave summarizes radio and channel utilization information of network traffic for the last week and puts the data in interactive RF capacity graphs on the Radios page. You can find these graphs by navigating to Home > RF Capacity. These graphs refresh after nightly maintenance completes. The process goes over all the radios and determines the maximum client count and maximum channel utilization for each radio.

AirWave displays three sets of data for 2.4 GHz, 5 GHz, and 6 GHz radios:

• Radios by percentage of time over 80% utilization—These graphs show the percent of the time that the radios are above the threshold during the day when in use. AirWave determines the normal usage time based on stored utilization samples. Values in red indicate that these radios are above the threshold 75 to 100% of the time. You might want to investigate these radios to see if you need to upgrade them or add additional APs to this location. The information on this graph is collected every 24 hours, after nightly maintenance, and includes data from the last week. You can click on a bar in this graph to view details in a pop-up window.

• Radios by peak channel utilization—This graph shows the total number of clients connected to radios and corresponding radios connected during peak channel utilization. Data collection occurs every 24 hours, after nightly maintenance, and AirWave includes utilization data from the last week in this graph. You can click plot points, which represent radios, to view historical utilization information for the last two hours, day, week, year, or view a custom time range in a pop-up window.
