5.4.3.3 Handover overlap areas
Fig. 3.28: Planning handover overlap areas
How to evaluate the field strength measurement values and specify the overlap
areas is described in "Measurements", page 656.
5.4.3.4 Location areas
With incoming calls each handset is called by the system simultaneously via all the
radio units of the location area in which the handset is logged on. If a handset
switches from the coverage range of one location to that of another, the handset
will log into the new area from scratch. The logon procedure is automatic and
does not affect the use of the handset. To prevent handsets from constantly log-
ging themselves on in locations areas, plan the overlap areas of location areas in
such a way that handsets are not permanently located there.
Distributing the radio units over several location areas ensures that the radio traf-
fic involved in locating handsets for incoming calls is distributed across the loca-
tion areas. This means that overall more calls can be processed simultaneously.
• To guarantee a clean handover, the
radio units should be fitted in such a way
that the 35–40 dBµV limits are at least in
contact.
• When conducting survey measurements
in unfinished buildings, the limits should
be increased by 10 dBµV.
