Dect Overview - Aidcall Touchsafe Pro IP-DECT 400 Single-Cell Installation Manual

5. DECT OVERVIEW
The maximum theoretical range for any DECT system is 500 metres under ideal conditions, in practice the
range will rarely exceed 300 metres 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 50 metres radius from the
Server/Base Station or Repeater.
Locating the Server/Base Station as high and free from immediate obstruction as possible will help to
maximise its range. Even if the Server/Base Station is placed in the optimum position it may not always
achieve coverage in the most remote corners, if this is the case then additional Repeaters will be required.
Repeaters are generally placed in a star configuration around the Server/Base station; however, it is
possible to extend the coverage in one direction with up to 3 repeater jumps. A site survey will be required
to establish the best DECT system and Base/Repeater configuration required.
The Server, Base Stations and Repeaters should always be located at least 5 metres away from the
Nursecall Panels, RFE's or any other electrical equipment to avoid the risk of interference.
All DECT products 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 DECT system to ensure full radio
coverage and correct Radio Part Numbering of Base Stations and Repeaters. Failure to follow the
Manufacturer's installation and programming instructions may result in blind spots or calls dropping‐out
when moving between radio cells. Always perform several test calls in all extremes of the building with all
DECT handsets in use, i.e. simultaneous phone‐phone calls.
