HiPath Cordless IP, Service Manual 17
2 Overview
The HiPath 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 HiPath 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.
HiPath 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 Siemens-specific features.
