The VoWiFi Handset as a Troubleshooting Tool

The handset provides the following kinds of built in troubleshooting tools that display
information directly in the handset LCD:
• Information about the configuration of the handset. The Device Info menu is used by the
support engineer to check handset configuration parameters.
• Information about the site that the handset operates in. The Site survey tool is used by
the support engineer to check for possible RF problems caused by the layout of the site.
• The Admin menu for setting certain handset parameters and accessing logging tool
menus for troubleshooting the RF environment
Handset commands are accessed using shortcuts. To use a shortcut, ensure that the handset
main screen is displayed and then enter a shortcut in the format described below:

Handset Device Information

The support engineer uses the handset information to check the values of parameters that
define the configuration of the handset. Some of these entities are static, for example, the
values of the software configuration parameters reflect the date, time and version of the
last software upgrade. Other parameters however are dynamic, and vary under different
circumstances. For example, the SSID and channel number parameters will change as the
user roams through the network.
To display information about the configuration, select Menu > Settings > Device info or use
the shortcut *#34#. Detailed device information about the configuration of the handset is
described in
5.2

Site Survey Tool

The handset is the recommended tool for performing a site survey because of its radio
performance. A laptop computer does not share the same characteristics as a handset and
should not therefore be used to perform site surveys. To display site survey information in
the handset, use the shortcut **#77#.
The site survey tool can be used to:
• Measure signal strength from all APs in the network
• Check for roaming candidates
• Detect areas with co-channel interference
• Detect rogue APs
• Check the channel plan, that is, check channel settings and APs coverage area.

Show RSSI

The Show RSSI menu item displays information in the handset LCD about the received signal
strength, the current and previously associated APs and whether the handset is in power
save or active mode during the association. To show RSSI information directly in the handset
display without navigating through the Site Survey tool menu, use the shortcut **#76#.
