TETRA vs. DMR - a Comprehensive Comparison

Professional Mobile Radio (PMR) addresses the need of users regarding reliable and flexible wireless speech and data communication in a local, regional, national and global environment. Analogue PMR systems still dominate in various areas.

Professional Mobile Radio (PMR) addresses the need of users regarding reliable and flexible wireless speech and data communication in a local, regional, national and global environment. Analogue PMR systems still dominate in various areas. They are applied and operated in various sectors e. g. education, government, manufacturers, energy, public safety, utility, transportation. Some companies still rely on public mobile radio or still have not thought of a systematic use of mobile speech and data communication. Analogue PMR networks are replaced step by step by digital PMR systems. The most prominent digital PMR systems available today are TETRA and DMR. At first glance both systems are complementary. TETRA is more suitable for mission critical applications while DMR was designed for enterprise critical applications. When you go into the details the choice between the two systems is not so clear. 


This course was set up to enable the participants to judge the two systems more reliably. We start with an introduction in the basic principles of digital mobile radio and digital trunked radio. The next two sections discuss TETRA and DMR respectively. The two sections are structured similarly and cover technical as well as user aspects. We discuss the most important services and features. Additionally the course describes the function of the different network element and the typical network architecture. We deal with terminals and the interoperability of different terminals in different networks. You also get a market overview. We conclude with a systematic comparison which leaves room for discussion of the specific needs of the participants. In this course we deliver sufficient knowledge so that you are able to attend more advanced and more specific courses on digital DMR.

Target Group / Requirements

The course is intended for a broad audience including analogue PMR users, potential PMR users, and engineers, other technical and administrative staff involved in the planning, implementation, modernisation, optimisation and further development of PMR networks. The course addresses also technical and administrative personal of enterprises which didn't use PMR communication so fare.
