Planning an IP-DECT system

Client requirements

When you plan an IP-DECT system, ensure that the system meets the needs and requirements
of the customer. Discuss with the customer in which area the customer requires high quality
network access and where lower network sound quality is sufficient, for example, outdoors or in
a production hall.
Also discuss coverage in special areas such as lifts, stairwells, basements, indoor car parks,
toilets and maintenance shafts.
The customer might need higher traffic capacity in some areas or departments, for example,
sales, purchase, technical support departments, and canteens. So you must add base stations
in these areas. For information on how to calculate traffic capacity, see
system on page 55

Base station coverage

Architecture, building elements, and special areas affect the coverage and the placing of the
base stations.
The radio environment or the cell that a base station covers is not spherical in shape but much
more irregular. The momentary size and shape depend on the material of the walls and floors,
the position and material of the furniture, machines, air-conditioning, and the position of the
base station in such an environment. While these unpredictable conditions make formulating
specific rules on how to calculate the number of base stations in a given situation difficult, the
following are some guidelines:
The in-house cell size in offices can have a radius of between 10 and 30 meters, see
●
Example of base station location in a building.
production halls can have a radius of up to 200 metres.
The free space outdoors cell radius can be up to 300 metres.
●
Base stations might partially cover the floors immediately above and below. The useful
●
range through floors and ceiling varies between 0 and 8 m (2 floors) radius.
See Example of base station location in a building.

Architecture

This section describes how the architecture of the building can affect the base station coverage.
Central areas giving access to stairs and lifts might require extra base stations due to
●
heavier constructions.
