Reliable wide area narrowband wireless data radio networks is the speciality of Radius. So when Siemens needed a data radio solution for their project to bring Distribution Automation to a number of locations in and around Dubai for their client DEWA they turned to Radius for the solution.

The choice of radio was the PDR 121, due to it's in-built data message routing function, the preconfigured list of protocols, including DNP3 and IEC870-5-101 and for its superior signal recovery and its on-air reliability and security. Added to the fact that the PDR range is one of the only data radio products in the world specified and fully compliant in temperatures up to 65 degrees C.
