TETRA system has been chosen by one of Germany’s largest open-cast mining companies to replace its existing analogue radios.
MIBRAG (Mitteldeutsche
Braunkohlengesellschaft mbH), a major producer of lignite (brown coal), employs around 2000 people and operates two large open-cast mines, in the states of Saxony and Saxony-Anhalt. From these two sites it produces some 19 million tonnes of lignite annually, most of it destined for the nearby Lippendorf and Schkopau power stations. In upgrading to a modern digital radio system, MIBRAG wanted to ensure that all
critical communications could be reliably received. It also wanted to optimize its operations and business processes. For the upgrade, the company has bought TETRA infrastructure from Selex Communications plus a fleet of 430 handportables and 230 mobiles from Sepura. Both types are equipped with Sepura’s highly sensitive GPS feature. “The move to TETRA is an important
forwards step for MIBRAG and will help us to further modernize our business processes”, commented Frank Possehl, MIBRAG’s project manager for the radio upgrade.

Moreover, we will get better access to the Asian market. This means enormous growth potential in the field of professional mobile radio.” Established in 1981, Rohde &
Schwarz Professional Mobile Radio joined the Rohde & Schwarz group in 1988 – at that time under the name R&S BICK Mobilfunk. In 2009, it became a wholly-owned Rohde & Schwarz subsidiary and was renamed. Hytera is a solution provider with a
wide base and a large product portfolio. It takes over the German business unchanged, including employees, contracts, customer relations and its location at Bad Münder, in Lower Saxony.
