Monitoring Predicted Coverage (RSSI)

Use MONITOR/Maps, click an item in the Name column, left-click the floor map, from the Protocol drop-down menu, select a protocol to access this page.

This page assumes that you have already added active access points to the selected map.

The display of predicted RF coverage on the map is determined by the selection you make from the Protocol pulldown:

•For 802.11a and 802.11b/g: This information is displayed in the panel next to the Cisco 1000

Series lightweight access point icon as follows: n% Failed (a+b), where n is the percentage of Cisco Radios that failed.

•For 802.11a: A colored overlay appears on the map displaying the coverage patterns for the 802.11a Cisco Radios. A Received Signal Strength Indicator (RSSI) Color Lookup appears at the top of the map indicating the meaning of the colors. The colors show the signal strength form RED (-35 dBm) through DARK BLUE (-85 dBm). Next to each Cisco 1000 Series lightweight access point is a percentage of failure.

•For 802.11b/g: A colored overlay appears on the map displaying the coverage patterns for the 802.11b/g Cisco Radios. Received Signal Strength Indicator (RSSI) Color Lookup appears at the top of the map indicating the meaning of the colors. The colors show the signal strength form RED (-35 dBm) through DARK BLUE (-85 dBm). Next to each Cisco 1000 Series lightweight access point is a percentage of failure.

A sample RF Prediction Heat Map with Cisco 1000 Series lightweight access points providing coverage at one end of a building appears in the following figure:
