5 Deployment Mechanics – Multi-cell SME Network
In this chapter we provide short description of practical cases of how Multi-cell SME VoIP network can be
deployed – unfold synchronisation details of how master bases latches to one or more slaves.
Case ##1: Synchronisation Chain with One Master Sync.
a) The Synchronisation chain must always overlap with other Base stations in order to latch each other in
Sync.
b) In this illustration Base station ##39 is the Sync Master
c) A maximum of 7 devices (Including the master bases) can be chained at a time
d) The other slave base stations or repeaters are connected to the Sync Master through the
synchronisation chain
e) If one of the base or repeater units in the sync chain is broken or not working, then the units that
follows non-working device are cut off from the sync chain. Therefore handover is not possible
between the non working units and working ones.
f) However, handover is possible in the deployment figure below, because e.g. both BS#01 and BS#02
overlaps with BS#39. Therefore when BS#01 is not active, handover between BS#39 and the rest of the
slaves is still permitted.
