Deployment Best Practices
When performing a site survey of an area where clients or tags are tracked, the RSSI of representative
devices should be verified to ensure compliance with the minimum number of recommended access
points and the RSSI cutoff. This should be performed via one of two techniques:
• Viewing detected RSSI for the client or asset tag using the show client detail <mac address> or
show rfid detail <mac address> controller CLI command, as shown in Figure 31.
• Viewing detected RSSI for the client or asset tag using the location floor map GUI, as described in
WLAN Clients, page 25.
Figure 31 Checking Client RSSI at the WLAN Controller
In either case, these commands should be performed with representative test clients or asset tags (see
Recommended Calibration Clients and Transmit Power, page 75) in the area where localization is
desired. When using the CLI approach, it should be performed in an SSH session to the appropriate
controller(s).
Figure 31 indicates that the output of the CLI command displays the signal strength of the client as
detected by all access points on the controller detecting the client. In situations where the detecting
access point registrations are distributed among two or more controllers, more than one SSH session is
required when using the CLI approach. From the information provided within the red area in Figure 31,
it can clearly be seen whether or not the client in question is being detected by three or more access
points at the recommended RSSI cutoff level or better.
