ASCOM Myco 3 - WLAN Planning and Provisioning

TROUBLESHOOTING GUIDE
Ascom Myco 3
WLAN Overview
Topic Comments
Are voice settings correctly set in the infrastructure,
both LAN and WLAN devices?
Voice packet must have precedence over other
types of traffic.
The assessment must check for the ability to create
an Quality of Service (QoS) solution across the
entire network.
Voice settings must be set according to vendor's
recommendation and interoperability reports.
Note: These reports provide important information
for ensuring interoperability between handsets and
vendor equipment. For further information
regarding the infrastructure, refer to the Ascom
Interoperability Reports for respective system
published on the Ascom Partner Extranet.
Is the right software version installed on the
devices?
Devices may need newer software or hotfixes to be
able to support new devices.
This is important when new features are added to
current protocols.
Is there sufficient RF coverage? Cell boundaries, cell overlap, and channel planning
are extremely important for mobile devices which
need to roam during usage.
RF coverage must be checked using Site Survey
tools.
3.2 WLAN Planning and Provisioning
To summarize, both a legacy WLAN that is to be upgraded to support VoWiFi and an entirely new WLAN
purpose build to support VoWiFi and probably other kinds of media require:
• Comprehensive site surveys and detailed maps and floor plans of the areas where the WLAN is to
provide coverage.
• Adequate provisioning of hardware, in other words, the deployment of sufficient APs in suitable locations
to meet the coverage requirements of the WLAN.
• Extensive and accurate documentation of the AP deployment using site maps and floor plans to illustrate
the deployment.
• A proper, well documented commissioning sequence including comprehensive testing.
• A rigorous acceptance procedure before the commissioning is signed off as meeting the voice, and
other, requirements, of the new or upgraded WLAN.
In addition, a legacy WLAN:
• Should have been documented properly to provide the basis and understanding implications of adding
voice.
• May require a complete reassessment of its existing infrastructure before voice is added.
