Certifying the Handsets
Prior to determining that an installation is complete, test the handsets following the sequence given in the previous Testing a Handset 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 Chapter 11 Troubleshooting for clues to possible sources of difficulties. If any adjustments are made to the system,
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 Polycom 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.
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.
