Motorola Solutions has been selected to modernise and expand the existing TETRA (Terrestrial Trunked Radio) digital radio system at the public transport alliance Rhein-Neckar-Verkehr GmbH (rnv).
The state-of-the-art system facilitates voice and data communication at one of the largest traffic alliances in Germany. Moreover, rnv has concluded an agreement with Motorola for the duration of 11 years, including technical 24/7 support, maintenance and repair, system upgrades and security updates ensuring smooth operation of rnv’s TETRA digital radio system also in the future.
rnv operates the suburban railway, tram and bus routes in the cities of Mannheim, Heidelberg, Ludwigshafen and Weinheim, as well as the regions of Rhine-Neckar, Rhine-Palatine, Bad Dürkheim and Bergstrasse with more than 164 million passengers per year.
The updated TETRA digital two-way radio system will enable optimal passenger services, support of rnv’s employees in the control of operations, as well as the regulation of the dynamic passenger information for all lines of rnv.
The project is managed by the prime contractor Trapeze Switzerland GmbH. The longstanding Motorola partner is one of the world’s leading companies in software solutions and intelligent transport systems for public and private transport organisations and authorities.
rnv will modernize its TETRA digital two-way radio system by implementing a new Motorola Dimetra IP Release 8.x TETRA system for secure and reliable mission-critical communication performance.
Motorola Dimetra IP Release 8.x includes automated system upgrade functionality, which reduces upgrade time as well as the need for specialist and expensive support staff. The new system achieves practically seamless upgrades by reducing service outages by more than 60% compared with the previous system release.
All 11 connected Motorola base stations will be updated to the latest software release. In addition, the entire TETRA digital two-way radio system will be made available for the adaption of the Intermodal Transport Control System (ITCS). The ITCS gives the dispatcher a real-time overview of rnv’s entire line network. The current location of any transport vehicle can be examined at any time.
The ITCS radio control station will be integrated through the new Dispatch Communication Subsystem (DCS) server architecture for establishing a virtual dispatcher solution and also providing an Ethernet interface for management and voice communication.
Moreover, the ITCS infrastructure will shift data transfer from packet data to short data enabling the application of secondary control channels in the Short Data Service (SDS) mode.
The service contract, which has been concluded by rnv and Motorola, with a duration of 11 years, ensures that the TETRA digital radio system will operate reliably and securely also in the future. The agreement includes technical 24/7 support of specialized technicians (Motorola Remote Technical Support Services).
Motorola also takes care of pro-active maintenance of the technology for optimal operation of the infrastructure as well as system upgrades and security updates ensuring that the TETRA digital radio system provides state-of-the-art functionality at any time. The contract also covers repair services and the exchange of defective components (Advanced Exchange Repair), eliminating unforeseen costs for parts at rnv.
Rhein-Neckar-Verkehr GmbH is the largest major traffic alliance in Germany that was formed by several cities. rnv operates the suburban railway, tram and bus routes in Mannheim, Heidelberg and Ludwigshafen. Furthermore, it is also represented in the southern Hesse region.
The approximately 200km long railway network is the longest single meter-gauge network in Germany. It includes bus, tram and suburban rail routes as well as two railway routes. With more than 1,800 employees, rnv operates 188 trams and light rail vehicles as well as about 173 buses.
Dr. Peter Raue, manager basic issues infrastructure and deputy operations manager BOStrab (German federal regulations on the construction and operation of light rail transit systems), Rhein-Neckar-Verkehr, said: “Due to the successful cooperation in the past years, we have chosen to continue our collaboration with Motorola and Trapeze in the future. We recognize the advantages provided by the reliability of the systems components and the resulting high availability of the entire system.
“The TETRA digital two-way radio system allows us to centrally coordinate and better manage our vehicles, employees and technical systems across the entire region. With the comprehensive system from Trapeze and Motorola, we have been able to provide more reliable offerings to our passengers – step-by-step – during the past years.”
