Since 2006 we have been operating seNet® in the Ruhr region – Germany’s largest digital professional mobile radio network. It complies with the European TETRA (Terrestrial Trunked Radio) standard for digital mobile radio. We also invite other companies to subscribe to our network. This places us among the technology leaders, as digital is by no means standard yet for professional mobile radio.

Our customers include oil refineries, municipal utilities, local authorities, fire brigades and taxi companies. All of them depend on having a stable, tap-proof radio network available around the clock, for communication in emergencies, for traffic and fleet control, and for coordination of operations.

For industrial customers and office complexes, we design, install and operate telephone systems with up to 2,000 subscribers. We also equip our customers for emergencies, with modern systems for early fire detection.

Our seNet® mobile radio network stands for customized solutions, reliability and flexibility in applications, enabled by state-of-the-art technology.
