Telent modernizes digital mobile radio network in the local transport region West Mecklenburg, Germany

The existing analog mobile radio infrastructure is to be replaced with a cutting-edge DMR network complying with the ETSI Tier 3 standard. telent will be responsible for planning the radio network, as well as supplying and installing the systems and infrastructure.

The new DMR network unites the advantages of mobile radio with those of a digital, mobile communication switching system. Modernization of the network will enable the transportation association to achieve great efficiency and flexibility in its mobile enterprise communication and take a major step toward implementing a state-of-the-art technology.

DMR offers the same coverage with the same frequency as the currently installed analog digital mobile radio system. The higher voice and data quality ensured by DMR in the entire area supplied by the network is a further key feature, as are secure emergency calls, flexible assignment of groups and channels and various priority levels in voice and data radio communications. A confidential radio call or defined group calling can be used alternatively. Apart from status messages and short data services, diverse IP data packet services are supported.

The crucial factor in choosing a DMR Tier 3 system was the transportation companies’ wish to improve communication between their stationary organizational units and vehicles and to make it multiclient-capable. That means that in future multiple transportation companies will be able to communicate with each other in the network without all the units having to listen in. The associated IP concept and the VPN infrastructure will be provided by telent.

“The use of cutting-edge equipment and integration in the existing radio network reduce the amount our customer needs to invest without sacrificing a high degree of future proofness for coming data applications,” explains Robert Blum, Managing Director of telent GmbH.

“Rollout of digital radio technology will create a network that plugs the existing gaps in radio communication and will cover the complete local transport region of West Mecklenburg with its area of around 7,000 km². The network can also be made available to other parties who need to use it,” says Andreas Plestinsky, Managing Director of VLP.  “In addition, it improves the possibility of establishing alternative services, such as call taxis or call buses. A fleet management system is to be set up in order to plan the journeys of alternative forms of transport,” adds Stefan Lösel, Managing Director of GBB.

So as to deliver a solid redundancy concept, the DMR base stations will be managed by two exchanges situated at separate locations. More than 300 vehicles will be equipped with mobile devices. telent is setting store by the advanced DMR product family DIPRA from its strategic partner RADIODATA for the system technology. Thanks to its open, multicellular tier 3 architecture, the DMR network can be expanded as desired. That makes the system excellently suited to implementing future requirements efficiently as well.
