The company "Rosel" has launched serial production of updated base stations for professional radio communications of the TETRA standard. According to the press service, the modernization is aimed at reducing energy consumption and simplifying operation at critical infrastructure facilities.
TETRA networks support group calls "one-to-many", GLONASS coordinate transmission and telemetry. In the new stations, the transceiver module, the connection module and the frequency generation module have been updated. Additional status indicators are displayed on the front panels for quick fault detection. Increased reliability is ensured by redundancy of control and power modules.
Previously, the Russian professional TETRA communications market was heavily dependent on imported equipment (Motorola, Airbus). The 2022 sanctions hit supplies and service. Rosel is one of the few domestic manufacturers that is replacing this niche. The new stations with an emphasis on survivability and ease of diagnostics are a direct response to the requirements of the fuel and energy sector and security forces, where communication failure is critical.
