N870 IP PRO Multicell System – Introduction
Handover and overload balancing can only be provided by synchronised base stations. In
some cases, not all base stations connected to one DECT manager can be synchronised for
location specific reasons. To organize synchronisation just within a subset of base stations
connected to one DECT manager, you can form clusters, within a DECT manager.
A DECT manager can offer multiple clusters with base stations synchronised within the clus-
ter, but not synchronised along different clusters.
In multiple DECT manager installations, cross-cluster synchronisation is possible via DECT
manager synchronisation (
