Proof of concept testing of backhaul of tetra base stations to IP and 3G links

摘要

TETRA system represents basic system for mobile communications for Ministry of Interior of Republic of Serbia, and as such it has high requirements for system availability and reachability. If we approach TETRA system architecture as special purpose celular system it is questioned if system can be migrated to IP network. Having in mind specific requirements of mobile system of MoI RS we have perfromed one step further in analysis. Expert teams of MoI RS, SAGA and Cisco have engaged in Proof of Concept testing of backhaul connectivity of TETRA BS through IP adn 3G links of mobile operators. 3G base stations are available in numbers on each part of teritory and are perfect choice for global available link, however it has been a great technical endeavour to enable backhaul connectivity of one mobile cellular system through other cellular commercial system, while maintaining high level of availability and reachability of system.
