Live RF

Live RF displays a heat map that represents signal coverage for APs placed on a floor plan. When the Floor Plan is accessed, if devices are in place, Live RF starts and a heat map is displayed.

Live RF data is available on all Floor Plan pages. When the Floor Plan is refreshed (manually or automatically), RF data is updated using the latest data (radio, power, channel, live status, etc.) about the devices. This data comes from the last polling cycle for the devices. If the Poll Devices button is clicked, the devices are refreshed first by AirDefense and then the RF data is updated and displayed in the Floor Plan.

The heat map can be filtered according to:

• Visualization/Application—Uses the visualizations and applications that configured in Configuration > Network Assurance > Live RF Settings.
• Protocol—Uses one of the available protocols (802.11a, 802.11b, 802.11g, and 802.11n).
• Devices—Filters RF data by a single device, a group of devices determined by SSID, or all devices.

The Live RF Settings topic in the Configuration chapter fully explains how to use Live RF.
