required parameter settings of the devices supporting the WiFi system should also be
documented.
The following table lists some of the topics that should be included in an assessment
document:
Topic
Are voice settings correctly set in the
infrastructure, both LAN and WLAN
devices?
Is the right software version installed on
the devices?
Is there sufficient RF coverage?

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.

2. WLAN Overview
Comments
Voice packet must have precedence over
other types of traffic.
The assessment must check for the ability to
create an QoS solution across the entire
network.
Voice settings must be set according to
vendor's recommendation and Ascom inter-
working reports.
Note: These reports provide important
information for ensuring interoperability
between Ascom handsets and vendor
equipment. The reports are published as
Application Partner Program, Ascom Inter-
Operability Reports on the Ascom Partner
web site.
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. For example,
when 802.11n is added to a WLAN.
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.
