632 Planning DECT systems Part 3
The optimum number of location areas depends on the number of handsets in
the system and the traffic density (see page 633). The diagram below shows the
minimum number of location areas to be created out of the maximum of four
areas.
Fig. 3.29: Minimum number of location areas for different traffic densities
The following points need to be taken into account when dividing up radio units
into location areas:
• As of approx. 60 handsets the radio units in the system have to be divided up
into several location areas.
• If more than 9 incoming calls are to be signalled simultaneously on the hand-
sets, the radio units of a system need to be spread over several location areas.
No more than 9 calls should be made simultaneously in each location area.
• The radio units of any given location area should cover a contiguous area (see
example on page 616).
• Handsets should be used mainly within the same location area.
• Handsets should not be continually used in the overlap zone between two loca-
tion areas.
