l RSSI (Received Signal Strength Indicator) - IEEE defines RSSI is a mechanism by which RF energy is to be
measured by the circuitry on a wireless NIC (0-255). RSSI is not standard across vendors. Each vendor
determines their own RSSI scale/values.
l Session - A session is an instance when a client connects to the network. The period of time in which the
client remains connected to the network is typically calculated as a single session. However, if a client roams
between APs, the periods of time the client connected to the different APs may be calculated as separate
sessions.
l Unassociated Client Information - Some APs/Controllers have the ability to report the signal strength of
visible clients that are associated to a radio on a neighboring AP. W-AirWave also uses these signal strength
readings to more accurately place these unassociated clients.
l VisualRF - The W-AirWave service that calculates location, calculates path loss, and provides floor plan editing
capabilities.
l VisualRF Plan - Makes the planning portions of VisualRF available in an offline software package that does
not require a server. For more information about VisualRF Plan, see "About VisualRF Plan" on page 337.
Starting VisualRF
In order to launch VisualRF, AMP Setup >General settings must be configured to display the VisualRF tab, and
the VisualRF engine must be enabled using the VisualRF > Setup menu. Both of these pages are only visible to
users logged-in with administrators credentials. By default:
l Display VisualRF is enabled in AMP Setup > General.
l Enable VisualRF Engine is disabled in VisualRF > Setup.
To enable VisualRF, follow these instructions while logged in as an administrator:
1. Navigate to VisualRF > Setup.
2. In the Server Settings section, select Yes in the Enable VisualRF Engine field, and then select Save.
Basic VisualRF Navigation
The top-level VisualRF menu shows only the Network view, as shown in Figure 171.
Figure 171:Default VisualRF Top Level Menu - Network View
The top-level Network view can display network campuses on a map, or in a list. You can toggle between these
two displays by clicking the Map or List links at the top of the Network view.
Network View Navigation
The Network view provides page specially for viewing campuses, buildings and floors within your network.
You can select any campus or building to view the numbers of APs and clients at that location. Figure 172
displays an example of a campus view with a building icon selected:
