For connecting distribution network control systems (SmartGrid) utility companies require cost effective and secure data transmission. Security usually is demanded by national regulatory bodies. If no wire-bound transmission is available, e.g. in sparsely populated areas, suitable radio modems can fulfill this function. Also, radio modems may serve as a second transmission path.

Furthermore, radio data modems facilitate, among others, the transmission of operational data in mining, control und supervision of renewable energy sources, as well as transmission of measuring data of water and gas utilities.

Common to all these applications is the requirement of secure data transmission, independent of public networks and especially in situations like wide area power cut, big public events and natural disasters.

The radio data modem RADIUM serves as a link for Supervisory, Control and Data Acquisition (SCADA) equipment to a DMR Tier III trunked radio network. RADIUM is part of DIPRAcontrol, the RADIODATA solution for SCADA-over-Radio applications. It is fully compatible to RADIODATA DIPRA® radio systems. Available interfaces are Ethernet, RS232, RS485 or to Controller Area Networks (CAN).

Special data reduction methods facilitate a very efficient transmission of SCADA protocols IEC 60870-5-101 and IEC 60870-5-104.

The conversion of typical meter protocols like DLMS or IEC 61131 into the SCADA protocol IEC 60870-5-104 permit seamless integration of metering into the overall SCADA system.

DIPRAcontrol and RADIUM highly consider requirements of IT-Security. Preserving Confidentiality, the symmetrical encryption methods AES128 and AES256 are supported, as often recommended by national regulatory bodies. Furthermore, a Keyed-Hash Message Authentication Code (HMAC) is exploited to maintain Integrity for data packets submitted.

Availability is determined by the global design of the DMR Tier III radio network.

The LINUX operating system and the powerful microprocessor of the RADIUM radio data modem are the basis for development and integration of custom-tailored applications. Deploying Software Defined Radio (SDR) technology permits to implement special solutions with higher data rates than DMR normally can provide.

Configuring of the RADIUM data modem is done by means of a web interface which is provided by an integrated web server. Thus, it could be omitted to install a dedicated configuration software on a service technician's computer.

The compact design permits room-saving installations on DIN rails, mounting plates and in 19" racks.

For deployment in harsh environments the variant RADIUM-R is offered which conforms to protection class IP65 (dust-tight, protection against jet water from any angle). The M12 connectors employed for this variant ensure good contacting even under tough conditions.
