5 Planning DECT Systems

The following sections take you through the planning procedure for an
Ascotel DECT system (DECT: Digital Enhanced Cordless Telecommunications). It
contains recommendations on the project sequence and on handling the measur-
ing equipment. For general information on the Ascotel DECT system and its fea-
tures, see "Cordless Terminals", Page 1.64.
New Planning
A wide range of subjects have to be clarified in depth with the customer before
planning a DECT system. DECT systems are very high-performing, which is why
they need to be explained in detail. The better customers are informed, the more
they will use the system’s features, which in turn means the application will be
used more efficiently.
The following points are to be observed in general:
• Radio coverage area, capacity in terms of the number of connections
• Known problem areas and what to do about them
• Handover behaviour and what happens during a handover
• Cordless groups and other features
Project Extension
There are different types of extension:
• Additional handsets without a notable increase in traffic
– only new entries in the PBX numbering plan
• Additional handsets with an increase in traffic
– entries in the PBX numbering plan
– Existing radio cells, possibly needing to be reinforced with additional radio
units (warning: radio cells become smaller, resulting in a shift in the hando-
ver limits)
– Radio units possibly needing to be distributed to other location areas
• Coverage required over a greater area
