You do a site survey to check that you have your base stations placed so that the handsets can connect easily. Each base station has radio coverage of about 164 feet (50 meters) indoors and up to 984 feet (300 meters) outdoors. However, there can be interference with other equipment as well as poor coverage because of wall and door construction (for example, fire doors).
You perform a site survey:
During initial setup: you can place your base stations in temporary locations and power them on. They don't need to be connected to the LAN. You perform the survey to check that the handsets can communicate with the base.
After setup is complete: you can perform a survey to ensure that the system is working correctly and to troubleshoot user connection problems.
You use the handset to check that coverage is good for your users in all the areas to be covered.
In the handset, you can adjust the signal strength for the handset radio. However, we recommend that you speak to your service provider or Cisco TAC to discuss the signal strength change.
Perform this task when you set up your system and when there are changes to the area (for example, changes to walls, or new areas added).
Before you begin
You need at least one handset fully charged.
On the handset, press and hold Power/End until the screen turns on.
Enter *47* to get a list of base stations within range.
(Optional) Press Settings to view the dBm threshold for the ranges.
To change the range,
Highlight a MAC address and IP address pair in the IP Search list and press Select.
The screen displays this information about the selected base station:
Press Power/End until you return to the main screen.
Move to a different location and repeat Steps 2, 3, and 5 to check the coverage.
