TETRA, DMR Tier III, TEDS and Analog in one box
Supports VHF and UHF in all technologies
Flexible, cost-efficient solution with up to four carriers in one box
Lets you build coverage in a completely new way
A world first
The world’s only outdoor base station featuring multiple technologies in one single core-connected system: TETRA, DMR Tier III, TEDS and Analog. This technology-independent solution features multiple carriers as well as simulcast in one box within either UHF or VHF frequency ranges.
No more need for gateways or bridges! With the core-connected BS422 you can easily combine multiple technologies in one coherent system. Or choose the one technology that matches your current need – and scale anytime to meet changing voice and data needs with a simple click.
Multiple technologies – one software
With everything covered by one system, operation, maintenance and repairs are simply easy. Multi-technology networks can be managed in a single network management tool with one central subscriber register. Applications like dispatchers and voice and data log systems can be used across all technologies, and all technologies use the same gateways.
The BS422 can be set up as a stand-alone system. It can also be seamlessly integrated into any existing DAMM single-tech network such as networks based on DAMM BS421 outdoor and/or DAMM BS418 indoor base stations.
Rugged and compact design
The BS422 is built to withstand harsh conditions – from extreme cold to extreme heat and also wet conditions thanks to its IP65 encapsulation. Its compact and light-weight design makes it easy to install everywhere from masts to tunnels and on the back of a truck.
No single point of failure
At the core of the BS422 is a decentralized architecture, which ensures that all system information is constantly replicated to all sites in the network. This means that the system does not have any single point of failure.
This way, local call and data traffic will run without interruption, even if one site loses its connection to the rest of the network.
Flexible and future-proof
The flat decentralized IP architecture and intuitive software also enable effortless, self-configuring site expansion. The BS422 can be used with single or multiple carriers as well as single or multiple technologies, giving you maximum flexibility.
DAMM Frequency Sharing
Frequency sharing with the BS422 lets you build coverage in a completely new way: Simple, cost efficient and reliable.
Frequency sharing – Improve spectrum efficiency
Frequency sharing allows adjacent BS422s to use the same frequencies. This is a significant benefit in low density networks and gives the possibility to cover for example a railway line with just two frequency pairs.
Frequency sharing – Simplify repeater systems
With frequency sharing an indoor repeater system can be built without optical fibres. The same hardware can be used as base station and repeater unit, increasing redundancy and simplifying the network architecture by having one unified network management system and reduced spare part stock.
Frequency sharing – Obtain base station geo-redundancy
With the BS422 network availability can be brought to a new level. Two BS422s located at two sites can act as one fully redundant base station, sharing the same frequencies. This will add redundancy not only to the base station, but also to the whole antenna system.
Frequency sharing – Enhances frequency efficiency of TETRA
With its advanced voice and data features and high level of terminal interoperability, TETRA is often the preferred technology for radio communication across a wide range of industries. Having four channels on each frequency makes it the preferred choice for mid to high user density networks.
Using frequency sharing you can now make TETRA as frequency efficient as other technologies in low density networks. This means that you take advantage of all TETRA features without giving up on frequency efficiency, quality of coverage or network resilience.
