4/1/05 Finding Coverage Holes
OL-7426-02
- In the pulldown menu, select Present Map (high/low resolution) to dissociate and
then locate the client after reassociation. If you make this choice, Cisco WCS displays a
warning message and asks you to confirm that you want to continue.
Note that Cisco WCS Location (AIR-WCS-WL-1.0-K9 and AIR-WCS-LL-1.0-K9) compares RSSI
signal strength from two or more Cisco 1000 Series lightweight access points to find the most
probable location of the client, and places a small “Laptop” icon at its most likely location.
Note that Cisco WCS Base (AIR-WCS-LB-1.0-K9 and AIR-WCS-LL-1.0-K9) compares RSSI
signal strength from the client, and places a small “Laptop” icon next to the Cisco 1000 Series
lightweight access point receiving the strongest RSSI signal from the client.
Refer to the following illustration for a Heat Map showing client location.
Finding Coverage HolesFinding Coverage Holes
Coverage holes are areas where clients cannot receive a signal from the wireless network. The
Operating System Radio Resource Management (RRM) identifies these coverage hole areas and reports
them to Cisco WCS, allowing the IT manager to fill holes based on user demand.
