Performing a Site Survey Verification
After the initial deployment of wireless phones in the WLAN, it is a good practice to perform site surveys at regular intervals to verify that the APs are providing adequate coverage and that wireless phones can roam from one AP to another with no audio problems.
You should use the wireless phones and the Aironet Client Utility (ACU) to verify that the signal range and transmission power meet the recommendations for an optimal wireless voice environment. See the "Requirements for an Optimal Wireless Voice Environment" section.
Use the following topics for information about performing the site survey.

•
Site Survey Verification
For more detailed information about performing a site survey verification, refer to the " Wireless IP Telephony Verification section in the Cisco Wireless IP Phone 7920 Design and Deployment Guide.
When you perform a site survey verification and encounter problems, see the Chapter 9 "Troubleshooting the Cisco Wireless IP Phone 7920" for assistance with finding the cause of the problem.
To perform a site survey verification, use the following checklist:
