Download: Reliable and Scalable TETRA Networks
The evolution of TETRA networks towards an all-IP architecture is now a reality and has been accepted by even the most demanding users of TETRA technology. Although circuit switch based TETRA networks are still operational and are even still being rolled out today, the trend is towards deploying open IP-based solutions for both small and large TETRA networks. In this context, an all-IP architecture means that both the core of the network and the transport network are based on open IP standards and solutions.
Users who are considering investing in an all-IP architecture for their TETRA networks have a number of options available to ensure mission-critical reliability and scalability. In the past, proprietary IP protocols and equipment were developed by TETRA network suppliers to cope with the limited redundancy features and performance of standards-based Commercial Off The Shelf (COTS) routers, switches and link equipment, resulting in scalable but proprietary solutions. Other TETRA network suppliers did recognize the benefits of using low-cost standards-based IP equipment, but did not really care about reliability and scalability.
With the recent arrival of carrier-grade IP networks based on Multi Protocol Label Switching (MPLS), it is now possible to benefit from standards-based IP equipment when building large TETRA networks with excellent reliability, scalability and performance for mission-critical applications.
This white paper considers the reliability and scalability aspects of the different TETRA network architectures, and investigates whether modern IP / MPLS networks can be of benefit to each of the known TETRA network architectures.
