2 Overview
The OpenScape Cordless IP solution extends the scope of the DECT standard
introduced for voice communication, making it now available for Voice over IP
infrastructures.
The radio range covered by the OpenScape Cordless IP system is made up of
DECT IP base stations that together form either an seamless network of
overlapping and synchronous radio cells or individual radio islands. The size of a
radio cell depends on local/structural factors.
Voice over IP infrastructures are connected via the SIP protocol. In their capacity
as mobile communication solutions, DECT radio cells are therefore an optimal
enhancement to SIP-compliant Voice over IP systems.
The DECT IP base stations support seamless handover in ongoing voice
connections, that is, moving from one radio cell to another during a call with a
DECT handset. The roaming function is also available for mobile stations.
OpenScape Cordless IP also supports the DECT protocol GAP (Generic Access
Profile) and the radio protocol PN-CAP. The basic function scope required by
ETSI is thus extended to include a number of Unify-specific features.
