TETRA is essential to the organisations using it; it is tightly integrated in the operational procedures and when organisations want to evolve to broadband those operational procedures will also need to evolve.
Simply switching TETRA off and switching critical broadband on in one go will not be possible, so TETRA and broadband will co-exist for quite some time until new procedures are written and accepted and adopted by the users. Even though the TETRA standard was created in the circuit switched world, it was implemented in the packet switched world as well and all vendors today have TETRA on virtualised servers. TETRA services and broadband services can both reside on the same servers in a hybrid period of evolution. The latest TCCA Roadmap concludes that a period of at least three years’ overlap will be needed and that the evolution must be carefully planned and executed.
