5. 3. 2. 2 Handover overlap areas
• 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.

How to evaluate the field strength measurement values and specify the overlap ar-
eas is described in "Measuring", page 44.
Aastra Intelligent Net:
Handover is not supported in an AIN with radio units on various nodes,
whose coverage areas overlap each other, since both systems are not run-
ning synchronously. This also applies to PINX in a PISN.
