Motorola Solutions has recently upgraded and expanded TETRA networks in two major German cities for the power company Vattenfall Europe Distribution. Systems in Berlin and Hamburg have been enhanced with additional redundant elements to improve resilience, and the software has been upgraded to the latest Dimetra Release 8.0 platform.

Motorola explains that Dimetra TETRA Release 8.0 delivers many new capabilities to users and enables significant reduction of operating costs for users through reduced site footprint, efficient site connectivity options and a reduction in power consumption of up to 60 percent.

For Vattenfall, the improvements will mean increased capacity and lower running costs through streamlined system upgrades and maintenance. The TETRA radio networks enable Vattenfall to communicate reliably with field employees at all times: even if public mobile or fixed telephone networks should fail during some disaster, it will still be possible for Vattenfall to contact its technicians because of the redundant infrastructure of the TETRA radio systems.
