The first DMR Tier III trunked radio system supplied by Hytera Mobilfunk has been commissioned in Germany by Mark-E, a subsidiary of the Hagen-based ENERVIE Group, one of the largest energy suppliers in the state of North Rhine-Westphalia with over 300,000 customers.
The scope of the project for Mark-E includes nine DMR base stations, two switching nodes connected to the telephone network, network management, a dispatcher system and over 80 mobiles for installation in vehicles and handheld radios.
On 19 November 2012, the system was set to test mode; once the test phase has been completed, operation will commence and it will completely supersede Mark-E's analogue private mobile radio system.
DMR (digital mobile radio) is a new digital radio standard for professional radio applications and has been specially tailored to the requirements of energy suppliers, transport companies and industries. DMR Tier III is the trunked version of the DMR standard.
Hytera said that the use of modern digital processes for voice and data transfer makes DMR particularly well suited as a successor to analogue private mobile radio systems, and it also helps mitigate the effects of an increasing shortage of frequencies in this frequency band.
