Fully flexible network
The TetraFlex® system is scalable and can handle anything from single-site solutions with small coverage areas to large-scale multi-site solutions, incorporating any indoor or outdoor TetraFlex® station. Together with the intelligent TetraFlex software, simple and smooth expansion of the station is possible, even during operation. The 100% IP-based technology enables the entire network infrastructure to be operational with all network devices connected in a single modern infrastructure without the need for a central switch.
Easy to install – anywhere
The simplicity of Plug and Play allows for easy setup and fast deployment. With an IP65 rating, the Damm TetraFlex outdoor base station is ideal for installation in harsh environments. The compact design allows direct mounting on antenna masts, buildings and towers, significantly reducing installation costs and feeder losses, while providing an ideal solution for rapid deployment in moving vehicles.
Security and reliability
Full battery backup support as well as redundant controllers, power supplies and carriers, TetraFlex meets your highest reliability requirements. The intelligent distributed architecture replicates information to all stations in the network, avoiding single points of failure.
Unlimited application integration
DAMM TetraFlex is supplied with application gateways for easy access to application programming interfaces (APIs), packet data gateways and voice gateways, allowing direct development of customer-designed applications or integration with existing telephone systems and control room equipment.
