If the DECT connection between base stations seems to be not reliable enough to permanently guarantee a stable DECT over the air synchronization, e.g., because they are separated by iron doors or a firewall, you can determine that synchronisation should take place via LAN. In this case you can switch to LAN synchronization where you also need to work with PTP master.


Advantage of LAN synchronization

  • No Synchronization levels needs to be configured.
  • When a base station fails (Not the LAN Master) it will not have any impact on the other base stations.

  • Fewer base stations required as the overlapping area of the base stations is smaller. The overlapping area for handset handover can be smaller, because neighbored base stations do not need to receive each other in stable error free quality, but they must still be able to detect each other for the process of dynamic channel selection.

Disadvantage of LAN synchronization

  • Base stations must be in the same network segment.
  • Precision Time Protocol (PTPv2), deviation must be lower then 500 ns (rms).
  • High reliable LAN network is needed, see below for the requirements.
