What kind of technologies are available, what are the advantages of technologies like TETRA and wireless routers?
SELEX Communications’ approach is to deploy a TETRA system in a new segment of pipeline, realizing a “TETRA Region” that can operate independently, but interoperable with the analogue systems. Main advantages of interoperable voice and data networks include the ability set-up individual calls, group calls, and to send SDS messages across different networks utilizing a unified numbering scheme. Easy and efficient interoperability relies on state-of-the-art platforms based on IP protocol suite. Convergence of TETRA with legacy radio systems, such as MPT1327, or fixed telephone and data networks is achieved through VoIP (Voice over IP) and Mobile IP protocols whereas the interconnection network is implemented utilizing the Softswitch concept. Thanks to this flexible and advanced approach, users are surprised to communicate transparently through many radio and fixed systems as it was one, where fast voice communications is granted along with multi-service professional features, supervised
