Chapter Eight: Certifying the handsets
Test the handsets according to the sequence given in the Testing a handset before
determining that the installation is complete. Also, conduct a Site Survey mode test
according to the directions given in the previous Diagnostic Tools section.
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
Chapter 12: Troubleshooting for clues to possible sources of difficulties. If you make any
changes 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.
You must perform these tests 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 Avaya 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.
The site survey discussed here does not replace an RF site survey conducted by
professionals who specialize in WLAN design and voice optimization implementations.
Avaya offers professional services including RF site surveys.
Note:
The handset’s site survey mode is not a replacement for a professional site analysis and
must be used only for testing, limited site validation, and troubleshooting.
Note:
The handset’s site survey mode does not include functionality to allow for analysis or
troubleshooting of 802.11n specific WLAN features.
1. Referring to Chapter 8 Diagnostic Tools, section Run Site Survey, put a
handset into Site Survey in the Any/Smry ESSID mode. Walk throughout
the site checking for any expected APs or other ESSIDs.
