Certifying The Wireless Ip Telephones; Conducting A Site Survey - Avaya 3641 Installation, Configuration And Administration

10. Certifying the Wireless IP Telephones

Prior to determining that an installation is complete, test the Wireless IP Telephones
following the sequence given in the previous Testing a Wireless IP Telephone section and
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 the section
Wireless IP Telephone 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.
These tests must be performed in typical operating conditions, especially if heavy loads
occur. The 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 Wireless IP Telephone in Site Survey
mode and walk the entire coverage area to verify all access points.

10.1 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. 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 and
Polycom offer professional services including RF site surveys.

The handset's site survey mode is not a replacement for a professional site
analysis and should be used only for testing, limited site validation, and
troubleshooting.

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 section Run Site Survey, put a Wireless IP Telephone into Site Survey in
the Any/Smry SSID mode. Walk throughout the site checking for any expected APs or
other SSIDs.
Then, walk the site again, in MyID/Smry ESSID mode, this time checking that every
location has adequate coverage and has good channel allocation.
There should be at least one AP stronger than -the minimum specified in the following

tables.
At any point, the strongest AP shown should be on a different channel than the next
best choice.
The handset configured for 802.11b requires:
