11. Certifying the WTs
Prior to determining that an installation is complete, test the
WT
s following the sequence given in the
previous Testing a WT section and conduct a site survey mode test according to the directions given in
the previous Diagnostic Tools section. Note any areas where coverage is conflicting or inadequate.
Note any system difficulties and work with your wireless LAN and/or LAN system administrator to
determine the cause and possible remedy. See the section WT Problems for clues to possible sources
of difficulties. If any adjustments are made to the system, re-test the device in the same vicinity to
determine if the difficulty is resolved.
The installer should not leave the site before performing installation verification.
These tests must be performed in typical operating conditions, especially if heavy loads occur. Testing
sequence and procedure is different for every installation. Generally, you should organize the test
according to area and volume, placing numerous calls to others who can listen while you perform
coverage tests. Note any areas with excessive static or clarity problems and report it to an OEM service
engineer.
The coverage test will also require you to put the WT in
Site Survey
mode and walk the entire
coverage area to verify all access points.
11.1 Conducting a Site Survey
Conduct a Site Survey of the installation, by walking the site looking for interfering 802.11 systems,
adequate coverage and channel assignment, and correct AP configuration.
4. Referring to section Run Site Survey, put a WT into Site Survey in the
Any
/
Smry
ESSID mode.
Walk throughout the site checking for any expected APs or other ESSIDs.
5. Then, walk the site again, in
MyID
/
Smry
ESSID mode, this time checking that every location
has adequate coverage (there should be at one AP stronger than -70dBm in all areas) and has
good channel allocation (at any point, the strongest AP shown should be on a different channel
than the next best choice).
6. Finally, use the single AP (
MyID
/
Detl
) display to check each AP, to ensure it is configured for
the proper data rates, beacon interval, 802.11 options enabled, QoS method, and security
method.
Make any necessary adjustments to AP locations and configurations and repeat steps 1-3 until the Site
Survey shows adequate coverage and correct configuration at every location.
The installation is not complete until these certification steps have been performed. Do not
hand out WTs at a site that has not been certified.
