Together with two partners, Comlab and Hytera Mobilfunk, in 2011 ErvoCom realized a new radio communication system for Regionalbahn Bern Solothurn (RBS). For this project we utilized TETRA technology for the first time. RBS is the first customer who received a TETRA Train Radio System by ErvoCom.
Over the years, the system has been continuously expanded with additional functionalities such as GPS positioning.
As part of the new procurement of another 14 trains (Worbla), ErvoCom was also awarded to supply the train radio system and a part of the passenger information system.
The high level of customer satisfaction in 2018 also led to ErvoCom being awarded the contract to plan and renew RBS's entire Tetra radio infrastructure. The project was implemented in stages between 2019 and 2021, resulting in the installation of 13 new TETRA radio base stations.
