Site Survey Guide for Deploying Cisco 7920 IP Phones
OL-6315-01
Chapter 2 Survey Tools
The Cisco access point displays the signal strength of the packets from the client. The signal strength of
the access point as reported by the client utility should be relatively close to the signal strength reported
by the access point for the client. It is important that the signals between the access point and the 7920
be relatively the same. This design avoids a call in which one side of the call has poor connectivity.
The Station Information and Status page on the access point shows the signal strength of the client as
seen by the access point. Figure 2-10 shows the access point Station Information and Status page, with
client signal strength at -31 dBm.
