The BS422 Outdoor Base Station features a broad range of technologies in one single core-connected system, including TETRA, DMR Tier III, TEDS and Analog. The technology-independent solution has multiple carriers and simulcast in one box within either UHF or VHF frequency ranges.

Key features

  • 1-4 carriers per base station
  • VHF – 68MHz-88MHz, 146MHz-174MHz and UHF – 300MHz-400MHz-800MHz frequency bands
  • High output power, including 25W TETRA and 50W DMR Tier III
  • Integrated controller
  • Simulcast / repeater mode, including DMR Tier III and TETRA
  • IP65 encapsulation

Due to the core-connected design of the BS422, multiple technologies can easily be combined in one coherent system. It is also possible to run the system in one technology mode that matches the client’s current requirements. If voice and data requirements change, it can be scaled any time with a single click.

The operation, maintenance and repairs are simple because everything is covered by one system. Multi-technology networks can be managed in a single network management tool with one central subscriber register. Applications such as voice and data log systems and dispatchers can be used across all technologies just as the same gateways are used for all technologies.

BS422 can be set up as a stand-alone system. It is also possible to seamlessly integrate it into any existing DAMM single-tech network, consisting of DAMM BS421 outdoor and / or DAMM BS418 indoor base stations.

In open rural areas, users can save on infrastructure costs by using VHF frequencies to obtain the same coverage as UHF with fewer base stations.

Simulcast for DMR and Analog is easily enabled with the BS422, which also offers repeater functionality for TETRA and TEDS.

The BS422 is IP65-encapsulated and built to withstand harsh conditions, including cold, heat and rain. It can be easily installed everywhere, from masts to tunnels and on the back of a truck due to its compact and lightweight design.

Decentralised architecture is at the core of the BS422, ensuring all system information is constantly replicated to all sites in the network. This ensures that the system has no single point of failure and that local call and data traffic will run without interruption, even if one site loses its connection to the rest of the network.

The flat decentralised IP architecture and intuitive software enable effortless, self-configuring site expansion. The BS422 can be used with single or multiple carriers and technologies, providing optimal flexibility.
