WLAN Handsets to generate syslog messages. For information about configuring syslog
messages, see the documentation for the Wireless Security Switches and WLAN APs. For
information about configuring syslog messages on the WLAN IP Telephony Manager 2245,
see Configure the network
There are numerous third-party Syslog Servers available. You can use any RFC 3164-
compliant Syslog Server.

Access point planning

APs utilize radio frequencies to transmit signals to and from the wireless handsets.
It is essential to know where to install the APs to provide effective coverage for wireless handset
use. It is necessary to verify that coverage is available where it is needed. The first step is to
define exactly where the coverage is needed, which requires a site survey.
A site survey must be performed before installing a wireless LAN. A site survey is also
recommended when an existing network structure is modified or when physical changes
are made to a site.
Avaya recommends the use of the Site Survey Tool to perform the site survey.
A site survey is critical to designing and implementing a wireless LAN. The site survey is used to
determine the number of APs needed to support the wireless handset users and to determine
the best placement of the APs. Different AP vendors provide different tools to do this.

Site survey

To conduct a site survey, set up an AP at a particular location. Use a computer equipped with a
wireless LAN device and site survey software or a handset operating in Site Survey mode to
measure the strength of the signal from the AP. Move the wireless device around and repeat
the measurements to determine the optimum number and best locations for the APs. This
method helps identify dead zones and areas where building materials or other factors affect
the performance of the network.
Site Survey mode
The handset Site Survey mode displays negative dBm levels. These levels represent the
strength of the received signal (Received Signal Strength Indication or RSSI) from an AP. The
RSSI information aids in determining if WLAN coverage is adequate.
