Reliable coverage is paramount in a professional communications network.Better network coverage brings better public services. Providing network coverage everywhere, all the time, for the small numbers of         officers that are typically using a TETRA network is certainly a tall order.

But this is just what the Cassidian TB3 TETRA base station was designed to achieve. The TB3 can improve quality of service, provide more coverage, or achieve a combination of the two.
The TB3 can be used in a variety of network topologies to implement the best network availability and security. As well as coverage, the TB3 also helps deal with that other major headache – operating costs. For example, remote operation and maintenance greatly reduces these costs and is an important area pioneered by Cassidian TETRA System.
