TETRA - Model 1 -Autonomous Data Transmission System
TETRA communication infrastructure is generally the property of the network user or of a private institution. It is therefore autonomous and is not affected by the typical fluctuations in availability of public networks such as GPRS.
Fields of use
TETRA applications are in no way restricted to those of public safety organisations or simple speech transmission. Thanks to their secure and reliable communication links, TETRA networks can be used in many different ways and offer an interesting alternative to public networks in particular in the field of telecontrol, substation automation and automation technology.
The TETRA-1 data radio module can be integrated into existing networks via a V.24 interface and allows operation both in SDS and in PDA mode.
