Interoperability: A Key Focus Point in Rail
- This article first appeared in the Railway-News magazine Issue 5 2021.
India has one of the largest numbers of commuters in the world, putting enormous pressure on the public transport system.
It also puts pressure on the ability to allow different networks, technologies and systems to communicate seamlessly to ensure uninterrupted service and maximum safety. A key focus point in DAMM India’s rail solutions is therefore interoperability.
Different Interoperability Scenarios, Same Goal
The goal in any interoperability scenario is to maintain seamless communication without any limitations, including when operating different technologies or networks.
Interoperability can be relevant when:
- Migrating from one technology to another
- Running different technologies in one or multiple networks
- Needing to communicate with other networks
Bridging: Network Migration or Extension In the rail industry, the need for interoperability would normally arise when you either need to integrate other technologies or when you need to upgrade and expand your network. From Analogue to Digital Integration of or moving from analogue to digital is the simplest operation. Both scenarios can be solved using a radio bridge such as DAMM TetraFlex Group Bridge, which enables voice communication, simple messaging and basic interoperability between an analogue network and a digital network like TETRA or DMR Tier III. This way an analogue network can be integrated or gradually downscaled and moved to digital with the network running continuously.
