4/1/05 Monitoring Predicted Coverage (RSSI)
OL-7426-02
Repeat this section to assign Cisco 1000 Series lightweight access points to the remaining floor
plan maps.
You have added Cisco 1000 Series lightweight access points to floor plan maps. Continue with Using the
Cisco Wireless Control System.
Monitoring Predicted Coverage (RSSI)Monitoring Predicted Coverage (RSSI)
Use MONITOR/Maps, click an item in the Name column, left-click the floor map, from the Protocol
pulldown menu, select a protocol to access this page.
This page assumes that you have already added active APs 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.
Note: These two displays are popularly known as a “heat maps”, because they shows
the relative intensity of the RF signals on the Coverage Area map.
Note: Ensure you have the correct Cisco 1000 Series lightweight access point in each
location on the map with the correct antenna angle. This will become critical later on
when you are Finding Coverage Holes and Detecting and Locating Rogue Access
Points.
