Example 4: Shadows
If Base Stations are placed on pillars of
concrete or steel (e.g. in warehouses
with steel shelves or racking), shadows
may appear with no radio coverage. This
may be solved by covering the shadow
areas with one or more additional Base
Stations.
Using Repeaters
Introduction
A Repeater is used to extend DECT coverage. It is not a real Base Station and does
not increase the number of DECT traffic channels but it can give a larger physical
spreading of traffic channels and thereby extend the radio service of the traffic chan-
nels established with real Base Stations
The normal method of establishing multi-cell installations is to make pre-installation
site surveys to map the coverage and determine the number and location of Base
Stations. After the system is installed and tested, gaps in the coverage may be found,
or different coverage may be required, often in areas with limited traffic such as
basements, lofts or outdoor areas.
To increase the number of Base Stations requires further installation work. In such
cases the Repeater is ideal because it is not physically connected to the DECT sys-
tem and, therefore, is easier to work with.
No radio coverage – shadow
Steel shelves/racking No coverage - shadows
