Basics
General
If a DECT system is to operate faultlessly, a homogeneous radio hop has to be created that provides
sufficient calling opportunities (number of simultaneous connections) at the locations required by
the customer. The DECT test kit has been developed for this purpose.
With the equipment included in the test kit it is possible to determine the locations for the DECT
base stations as required by the customer.
The base stations are called Radio Fixed Parts (RFP). All 120 DECT duplex channels are used.
Initial considerations
Generally speaking the test kit can be used for two types of applications: planning a new project or
expanding an existing system. Both cases require in-depth consultation with the customer and a
maximum of detailed information so that the complex system can be configured as effectively as
possible. Providing the customer with comprehensive information allows him to make full use of the
available features, which will in turn result in high levels not only of application efficiency but also of
customer satisfaction.
The following points must be taken into account for new projects in particular:
• Radio coverage area, capacity in terms of the number of connections (“traffic density”)
• Known problem areas and what to do about them
• Handover behaviour and what happens during a handover
• Cordless groups and other features
With a project extension a distinction needs to be made between the following possibilities:
• Additional handsets without any notable increase in traffic simply require new entries in the PBX
numbering plan.
• Additional handsets with additional traffic require not only the entries in the PBX numbering plan
but also a verification of the existing radio cells to determine whether any boost is required using
additional base stations.
• Coverage required over a greater area
