In addition to the charts available in the Charts tab, the Wireless tab also includes wireless specific counters charts and wireless specific top N traffic charts.
Wireless specific counters charts show how the overall network traffic load on a radio varies over time. These charts are generated from the wireless counters data exported by sFlow. These counters charts are represented as stacked area charts. The wireless specific counters charts are:
A counters chart can only be displayed for a specific radio. If the Radio selector is set to All, the counters chart options are not shown in the Chart selector. You must change the radio selection to a specific radio before the counters charts options are available.
Top N traffic charts show the top N contributors to the network traffic and how the top N contributors change over time. These charts are generated from the sampled packets exported by sFlow. Top N traffic charts are shown using stacked bar charts.
The following wireless specific traffic flow charts are available:
The wireless specific Top N traffic charts show the top N contributors based on their associated traffic in either Bits/s, Frames/s or Air %. You can use the Units selector options to choose how the top contributors are calculated and displayed. The Air % option is only available when a specific radio is also selected. Air % is the percentage of the available bandwidth used by the traffic, taking into account the actual speed of transmission. Traffic transmitted at a low speed will have high air % utilization. This means that a host with poor signal strength may use a disproportionately large amount of wireless bandwidth and degrade performance for other users.
