Access Point Installation - Avaya IP Office 3600 Series Installation Manual

2.3 Access Point Installation

Installation of the wireless network access points will be largely dependant on the manufacturers instructions. That will
include instructions on the location of access points in order to ensure sufficient wireless coverage in the required areas
of usage.
1. Perform a Site Survey
Do not proceed with AVPP and 3600 Series phone installation unless a through site survey has been performed.
Perform a site survey following the instructions provided by the access point manufacturer. Most wireless phone
audio problems have to do with access point range, positioning and capacity. Performing a site survey can isolate the
access point causing these types of problems. If the wireless phone itself is suspected, conduct a parallel site survey
with a wireless phone that is known to be properly functioning.
Potential Problems
The following are the most common problems encountered which would be revealed by a thorough site survey.
In Range/Out of Range
·
Service will be disrupted if a user moves outside the area covered by the wireless LAN access points. Service is
restored if the user moves back within range. If a call drops because a user moves out of range, the wireless phone
will recover the call if the user moves back into range within a few seconds.
Capacity
·
In areas of heavy use, the call capacity of a particular access point may be filled. If this happens, the user will hear
three chirps from the wireless phone. The user can wait until another user terminates a call, or move within range of
another access point and try the call again. If a user is on a call and moves into an area where capacity is full, the
system attempts to find another access point. Due to range limitations, this may be the same as moving out of
range.
Transmission Obstructions
·
Prior to system installation, the best location for access points for optimum transmission coverage was determined.
However, small pockets of obstruction may still be present, or obstructions may be introduced into the facility after
system installation. This loss of service can be restored by moving out of the obstructed area, or by adding access
points.
Performing Site Surveys Using 3600 Series Phones
The 3600 Series phones can be put into a site survey mode. For details see section
