Site survey
To conduct a site survey, set up an AP at a particular location. Use a computer equipped with a
WLAN device and site survey software or a WLAN Handset 2210/2211 operating in Site Survey
mode to measure the strength of the signal from the AP. Move the wireless device around and
repeat the measurements to determine the optimum number and best locations for the APs. This
method helps identify dead zones and areas where building materials or other factors affect the
performance of the network.
Site Survey mode
Site Survey mode is used to check the signal strength from APs. When you select Site Survey
mode, the WLAN Handsets 2210/2211 remain in this mode until they are powered off. During
configuration, press the right arrow to skip this mode.
The WLAN Handsets 2210/2211 Site Survey mode displays negative dBm levels. These levels
represent the strength of the received signal (Received Signal Strength Indication [RSSI]) from an
AP. The RSSI information aids in determining if WLAN coverage is adequate.
For information on using the Site Survey mode, refer to “Appendix C: Testing the WLAN
Handsets 2210/2211” on page 109.
Site certification
Ensure the wireless handsets are adequately supported by the site.
Conduct a site survey. Note any areas where coverage is conflicting or inadequate. Note any
system difficulties and work with the system administrator to determine the cause and possible
remedy. Refer to “Conducting an effective site survey” on page 114 for information on conducting
a site survey.
The testing must be performed in typical operating conditions, especially if heavy loads occur.
Generally, organize the test according to area and volume, placing numerous calls to others who
can listen while coverage tests are performed. Note any areas with excessive static or clarity
problems and report it.
Note: The WLAN Handsets 2210/2211 do not require connectivity to a WLAN IP
Telephony Manager 2245 or the BCM to enable the Site Survey mode to be used. The
minimum configuration required is the ESSID of the WLAN or test AP and the WEP
keys, if applicable.
