Aastra RFP 32 User Guide DECT Site Survey Kit (EMEA) - Page 36

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 34
