When switching over to a DECT base station using different access
technology, a DECT terminal automatically re-establishes a con-
nection (roaming).
Synchronisation
Transmissions of all DECT base stations at a single location must
be synchronised in order that DECT terminals are able to receive
multiple DECT base stations simultaneously. Synchronisation can
be conducted via U
net/IP connection. DECT over IP base stations are thus synchro-
nised via wireless connection.
When planning a larger sized DECT network, it is advisable to take
the following points into consideration:
All DECT over IP base stations at a single location must be able
to receive at least one, or even better, two neighbouring base
stations. Synchronisation requires less signal strength than a
voice connection does.
Synchronisation range is increased using multiple base
stations. To decrease the probability of a connection
breakdown, base stations should not be arranged in chain
formation. The signal should be distributed with a network that
is as extensive as possible and where each base station is
supported by multiple synchronisation partners.
To re-synchronise, first wait for all current connections to be
terminated.
You can operate a DECT network consisting of several remote
locations ("clusters"). A cluster is a number of DECT base stations
that operate synchronously with each other. No handover is possi-
ble between DECT base stations from different clusters. You
should configure a second cluster for DECT base stations of a sec-
ond location.
Setting up the WLAN Function
The Forum Base DECT IP-WLAN indoor (v1 & v2) DECT over IP
base station provides the additional function of a Wireless LAN
Access Point (WLAN-AP). WLAN refers to data transfer by means
access. It cannot be conducted via an Ether-
