The DAMM Outdoor System BS421 is a mast-mountable and compact IP65-encapsulated TETRA communication system. This advanced and powerful base station transceiver and distributed controller is ideal for outdoor mounting because of its compact size and its rugged design, but is also equally well suited for indoor use.

Reduce OPEX with low base station power consumption

The compact design of DAMM’s outdoor TETRA system enables direct mounting on antenna masts, buildings and towers, reducing installation costs considerably. Thanks to the low power consumption, our base stations generate minimal heat. Together with the IP65 encapsulation, this removes the need for cooling fans that require maintenance. Redundancy also allows maintenance to be done without shutting down operations.

Full network flexibility

The DAMM Outdoor System is scalable and can handle sites of any size, from one-site solutions with local coverage to large-scale multisite solutions, using any combination of outdoor and indoor DAMM base stations. Together with the intelligent DAMM TetraFlex software, simple and smooth site expansion is possible, even while in operation. This means that railway extensions can be performed in a painless and cost-efficient manner.

The 100% IP-based technology provides full architectural network flexibility, with all network components connected in a single state-of-the-art infrastructure without the need for a central switch.

Multi-technology integration

This product is part of our single-technology portfolio, but can be fully integrated into any of our multi-technology products.

Easy to install anywhere

Plug-and-play simplicity enables easy setup and fast deployment. With its IP65 protection, the DAMM Outdoor System is ideal for installation in harsh environments like hot metro tunnels or along railway tracks. A compact design enables direct mounting on antenna masts, buildings and towers, reducing feeder loss and installation costs considerably, while also providing an ideal solution for rapid, vehicle-based deployment.

Secure and failure tolerant

Featuring full support for battery backup as well as redundant controllers, power supplies and carriers, DAMM Outdoor Systems meet your highest requirements on reliability. The intelligent decentralised architecture replicates information to all sites in the network, avoiding any single point of failure.

Unlimited application integration
