Using Maps

Figure 9-3 shows a second-order RF prediction. In this example, AP1 is set to 0 degrees, and AP2 and

AP3 are set to 90 degrees, so the three access points provide maximum coverage for the right wing of

the building. The access points in this prediction cover a smaller area because of the wall attenuation

factored in by the RF prediction algorithm.

Note Make sure you have the correct access point in each location on the map with the correct antenna angle.

Accurate access point positioning is critical when you use the maps to finding coverage holes and to

detect and locate rogue access points.

Monitoring Maps

These sections describe how to use maps to monitor your WLANs:

Monitoring Predicted Coverage (RSSI)

Follow these steps to monitor the predicted WLAN coverage on a map:

Step 1 Select the Monitor tab.

Step 2 Click Maps to display the Maps page.

Step 3 Click an item in the Name column and left-click the floor map.

Step 4 Select the 802.11 protocol to display on the coverage map. This information appears when you select a

protocol:

• 802.11a and 802.11b/g: the panel next to the access point icon displays n% Failed (a+b), where n is

the percentage of radios that failed.
