Certifying the Handsets
Prior to determining that an installation is complete, test the handsets
following the sequence given in
Testing a Handset, and conduct a Site
Survey mode test according to the directions given in Diagnostic Tools.
The installation may need some adjustments. 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
Troubleshooting 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 a NEC service engineer.
The coverage test will also require you to put the handset in Site
Survey mode and walk the entire coverage area to verify all APs.
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.
Step 1 Referring to Diagnostic Tools, section “Run Site Survey” on page 9-1, put
a handset into Site Survey in the Any/Smry ESSID mode. Walk
throughout the site checking for any expected APs or other ESSIDs.
Step 2 Then, walk the site again, in MyID/Smry ESSID mode, this time
checking that every location has adequate coverage (there should be at
least one AP stronger than -70 dBm 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.)
