TROUBLESHOOTING GUIDE
Ascom Myco 3 Troubleshooting Tools
5 Troubleshooting Tools
This section includes information about some recommended internal and external troubleshooting tools for
monitoring and analyzing data along with a list of common issues with suggested troubleshooting steps.
Build-in Troubleshooting Tools
The handset provides the following kind of built-in troubleshooting tools that present information directly on
the handset’s display:
• The site survey tool is used check information about the site that the handset operates in and the
possible RF problems caused by the layout of the site. For more information, please refer to 5.1 Site
Survey Tools, page 15.
• The Troubleshooting menu (in the Settings > Ascom settings) is used to access debugging and logging
tools. For additional information, start reading from the 5.4 Logging Scenarios, page 21 section.
• The integrated diagnostics tool (Factory mode) is used to check the handset’s hardware status. For more
information, please refer to 5.11 Diagnostics, page 31.
• Android battery health (Settings > Battery) is used to monitor the device’s battery life and restrict the use
of apps with high background and battery use. For more details on the feature, please refer to the
Android help center.
External Troubleshooting Tools
A support engineer should be also equipped with a software toolbox containing additional troubleshooting
tools commonly used in the trade. The toolbox should preferably contain tools for both the Wired and
Wireless LAN that are available from many sources like:
• WLAN and LAN infrastructure vendors: If you often work with a specific WLAN vendor it can be beneficial
to learn the tools that are produced by that vendor. Some tools may be free while others are costly.
• Niche commercial software publishers: Commercial software products are often highly priced but a
license will give you support, and there are often training programs available to attend.
• Free or low cost tools that can be downloaded from the Internet.
The tools that may be used are, in general, a matter of the support engineer’s personal preference.
However, when the support of the Ascom TAC team has been requested in resolving an issue,
they may request information, in the form of a trace or dump, from a specific tool.
External troubleshooting tools can be divided in the groups as follows:
• VoIP tools, such as software IP-PBX and software clients, performance measurement tools.
• RF tools such as spectrum analyzers, heat mapper tools, site survey tools.
• Air trace tools. For additional information, refer to 5.3 Air Traces of 802.11 Traffic, page 20.
• Protocol Tools, for example wireless supported Protocol Analyzer (Sniffer). For additional information,
refer to 5.2 Protocol Analyzer Tools, page 19.
• Report Tools.
5.1 Site Survey Tools
The handset is the recommended tool for performing a site survey to verify the VoWiFi system deployment.
This provides a true measurement of the RF environment based upon the radio of the handset. Wireless
analyzers can be used to provide additional assistance during a site survey. A laptop computer does not
share the same characteristics as a handset and should not therefore be used to perform site surveys.
The site survey can be done both for the cellular network and the Wi-Fi network using the handset.
