Cisco 7925G Administration Guide

AP Name: ap1
SSID: voice
Channel: 36
BSSID: 00:13:1a:16:cf:d0
RSSI: -59
CU: 10
Step 5
To verify the ability to roam between APs, walk through all areas where phones are used and take readings.
Approach areas from different directions to assure successful roaming conditions.
Step 6
Adjust AP and antenna placement and AP power settings to provide adequate coverage overlap.
Perform Site Survey
Use the Site Survey utility to actively and passively scan the wireless medium across all channels and to locate
APs that belong to the Basic Service Set (BSS). The results of the scans can help to identify areas of low
coverage, if any, and to determine whether the APs are configured consistently as recommended in the Cisco
deployment guidelines.
When you start the Site Survey utility, the phone disassociates from the current AP and remains disassociated
for the duration of the operation.
During Site Survey, both active and passive scans are performed at a rapid rate. These scans will result
in the phone battery life depleting faster than normal and might cause disruption to the wireless medium.
Caution
To use the Site Survey utility, follow these steps.
Procedure
Step 1
Configure the Cisco Unified Wireless IP Phone with the same SSID and encryption/authentication settings
as the APs.
Step 2
Power on the phone so that it associates with the WLAN.
Step 3
Choose SETTINGS > Status > Site Survey.
The phone displays a list of APs within range that have the same SSID and security settings as the phone. To
see more information about an AP, scroll to the desired line and press Details.
Step 4
To verify the ability to roam between APs, walk through all areas where phones are used and take readings.
Approach areas from different directions to assure successful roaming conditions.
Step 5
Adjust AP and antenna placement and AP power settings to provide approximately 20 percent coverage
overlap.
Step 6
When you terminate the site survey, a report is generated for you to view from the phone web page.
