Radio synchronisation
DECT base stations use the DECT radio interface to synchronize This ensures compliance with the CAP standard and optimum use of the readio channels.
Fig. K-2: Radio synchronization
One base station of the system is defined as synchronization (synch) master. It is recommended to install synch master and DECT master on one station. This means that all other base stations It does not mean, on the other hand, that all base stations must be in direct radio contact with the DECT master. A base station that is running in so-called slave mode can align itself with another base station, which is also running in slave mode.
Synchronization radius: The synchronization radius is the area around a base station in which other base stations can synchronize themselves.
Speech radius: The speech radius is the area around a base station in which a voice transmission to handsets is possible.
| Several base stations are configured as air synch candidates. According to the signal strength, the PARI master decides, which base station is the current Air Synch Master. If the current master fails, another one will be selected. |
