mission-critical communications



TetraNode, Rohill’s TETRA infrastructure solution, uses standard hardware and software components to create the most economical and powerful system currently available on the market. TetraNode’s flat network architecture based on nodes challenges the traditional hierarchical way of building networks. The principles of IP-networking are adopted in order to generate flexible network designs, which are scalable from single sites right up to deployment on a nation-wide scale.


TetraNode applies the latest soft-switch technology together with the most open, reliable Real-Time Linux operating system to produce a TETRA system of which all functionality is implemented through software, providing numerous benefits including increased flexibility, speed and integration of IP. The TetraNode Streaming Protocol (TNSP) has been developed to replace IP for the transmission of voice and data between TetraNode eXchanges (TNXs) and TETRA Base Stations (TBSs) due to certain limitations of IP for mission-critical communications. TetraNode is based on a minimum amount of standard PC and networking hardware, which makes it simple to install and maintain.

TetraNode is unique among current PMR solutions in allowing multiple air interface protocols to be networked together in a single, integrated, seamless solution. TetraNode uses standard software design tools for improved software quality and documentation. TetraNode has both a TetraNode IP Gateway (TIG) and a TetraNode Packet Data Gateway (TPG), which allow an infinite number of standard and third-party applications to be run over the TetraNode infrastructure. TetraNode is one of the very few solutions on the market – perhaps the only one – which can claim to support the full range of services and applications supported by all TETRA terminals available on the market.

TetraNode supports all available network topologies. Ample opportunities for redundancy and resilience are built into the solution, offering 99.999% availability of resources. Connectivity to other networks and devices is guaranteed through a wide variety of system interfaces. TetraNode has a number of additional special features, which include:

Finally, it is important to reiterate TetraNode’s complete adherence to the TETRA standard and other open networking standards as well as some special TETRA features not supplied by other systems manufacturers. TetraNode is a truly robust, powerful, open networking solution for mission-critical communications.
