【Multi-Cell】How to Register Base Stations to the DM
Last modified date: 2020/11/16 Views: 70

The W80 device must be registered to the DM for normal use. Whole registration process was divided into 2 phases: Discovery, Registration.


1.       Base Station Pre-registration

In the multicast network, you can pre-register all base stations at the DM. After that, the base stations will be automatically registered at the DM once being detected in the network.


Please refer the below parameters:

station.allowed.X.mac= Blank/String within 32 characters

station.allowed.X.name= Blank/String within 32 characters

station.allowed.X.sync.cluster= Blank/[1-10]

station.allowed.X.sync.level= Blank/[1-10]

---X is the pre-registration ID. X=1-30

2.       Manually Registering Base Stations to the DM

    2.1   W80-DM discovers W80-Base

Go to W80-Base’s web portal, find Base Mode in Status, then fill the IP of W80-DM to direct the base to DM.


     2.2   Register W80-Base to W80-DM

Go to W80-DM’ web portal, Under Base Station -> Base Station Registration, you can click Operation icon for base registration. 


Complete the corresponding information of the base station, and click OK. The base station is successfully registered to the DM.

Note: During configuration, assign one sync level to each base. Sync level 1 is the highest level, which is the level of the sync master and appears only once in each cluster.


        In registered list, you can click Edit to change the Base settings.



Base Station Synchronization

Base station synchronization is the prerequisite for the functioning of the multi-cell system, inter-cell handover, and overload balancing. Overload balancing means that a handset can roam to another available base when the current base is fully loaded and cannot accept further handset connections. Base stations can be synchronized "over the air", meaning that they are synchronized via DECT.

Note: : Synchronization always refers to a cluster. In case you set up several clusters that are not synchronized with one another, these will be no possibility of a handover or overload balancing between them

Synchronization Planning

Base stations in the multi-cell system must synchronize with one another to ensure a smooth transition of the handsets from cell to cell (handover). No handover and no overload balancing are possible between cells that are not synchronized.

The synchronization within a cluster takes place in a master/slave procedure. It means that one base station (sync master) defines the synchronization cycle for one or more additional base stations (sync slaves). A base station can synchronize with each base station on a higher sync level. The sync level concept allows base stations to automatically select the best suitable base station (having a lower sync level number) to receive synchronization signal from.

During configuration, assign one sync level to each base. Sync level 1 is the highest level, which is the level of the sync master and appears only once in each cluster. A base station always synchronizes itself with a base station that has a better sync level. If it sees several base stations with a better sync level, it synchronizes itself with the base station that provides the best signal quality. If it does not see any base station with a higher sync level, it cannot synchronize.

To ensure the synchronization, you should plan the level 1 base station in the center as much as possible, and place the next sync level's base stations around the center.

        The following is an example of a synchronization scenario:
