EUROMICRON: subsidiary telent supplies digital mobile radio to Stadtwerke Mainz Netze GmbH, Germany
The new DMR system is for the municipal utility a major step toward establishing state-of-the-art network technology, since it unites the advantages of mobile radio with those of a digital mobile communications system.
euromicron subsidiary telent supplies digital mobile radio to Stadtwerke Mainz Netze GmbH DMR network complying with the tier 3 standard
The municipal utility Stadtwerke Mainz Netze GmbH is entrusting telent GmbH - a euromicron Group company - with renewing its mobile radio system. The existing analog mobile radio infrastructure is to be replaced with an innovative DMR network complying with the tier 3 standard. telent will be responsible for planning the radio network, as well as supplying and installing the active technology and infrastructure.
DMR - High range, scalable functionality
The new DMR system is for the municipal utility a major step toward establishing state-of-the-art network technology, since it unites the advantages of mobile radio with those of a digital mobile communications system. Modernization of the networks will enable the company to achieve extremely high efficiency and flexibility in its mobile enterprise communication. A crucial aspect in choosing a DMR tier 3 system was the desire to increase the transmission capacity compared with the existing analog infrastructure so as also to be able to supply the territory of adjacent municipal and public utilities, which will also use the network. It is also envisaged that the additional capacities of this new network will be used for transmitting telecontrol signals via data modems.
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 so as to meet the requirements efficiently. A double DMR switch designed as a redundant hot standby and equipping of the sites with uninterruptible power supply units (UPSs), as well as connection of the base stations via SHDSL line transformers and radio relay links, also ensure high availability and fault tolerance, in particular in the event of a blackout.
Digital mobile radio in use
A further key economic advantage of the DMR technology used is that the same frequency range can be used and so locations, antennas and masts of the existing analogue infrastructure can largely be retained. Robert Blum, Managing Director of telent GmbH, explains: "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." 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.
The new mobile radio network permits a large number of parallel transmission channels. 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. That makes the system excellently suited to implementing future requirements efficiently as well.
