VoWiFi OVERVIEW
The maximum theoretical range for any VoWiFi system is 300 feet (92 metres) outdoors under ideal
conditions, in practice this range will rarely be reached due to reflections from nearby buildings, trees,
water, etc.
Obstructions inside buildings such as walls and floors will reduce the range, some construction materials
such as foil backed plasterboard, reinforced concrete or stone walls will reduce range further.
Environmental conditions such as high levels of transmission at nearby frequencies or emissions from other
electrical equipment may also reduce range.
Clear line-of-sight will give maximum radio coverage, it is impossible to state a specific indoor range in
advance of a site survey; however, as a guide you can usually achieve 150 feet (46 metres) radius from each
Mesh Access Point.
Locating the Mesh Access Point as high and free from immediate obstruction as possible will help to
maximise its range. Even if the Access Point is placed in the optimum position it may not always achieve
coverage in the most remote corners, if this is the case then additional Access Points will be required.
The Mesh Access Points should always be located at least 5 metres away from the Advent XT2 controller,
NTR’s
or any other electrical equipment to avoid the risk of interference.
Mesh Access Points must be sited in a dry secure area; they are NOT suitable for outdoor locations.

IMPORTANT NOTE:
Care must be taken during installation and commissioning of any VoWiFi system to ensure full coverage
and correct Mesh Access Point setup
. Failure to follow the Manufacturer’s installation and programming
instructions may result in blind spots or calls dropping-out when moving between Mesh Nodes. Always
perform several test calls in all extremes of the building with both VoWiFi handsets in use.
