Avaya cannot give precise recommendations for a site survey as every site will vary. However, a site survey is a prerequisite to installation in all cases. The correct and effective placement of base stations will prevent problems and maximize coverage. Most issues with any DECT system will arise from the number and positioning of the base stations.

The basic aim is to ensure:

• Base station coverage in all areas of expected DECT phone usage.
• Sufficient number of base stations covering each area for the number of expected simultaneous users (up to 8 per base station) in that area.
• Sufficient overlap between areas of base station coverage to allow for call handover when DECT phone users are moving.
• Where possible, synchronization of each base station with more than one other base station.
