Digital transmission networks and communication platforms

Q: What are the key requirements for digital transmission networks?

High security, high availability and low latency – particularly for safety-critical applications.

Q: What is the purpose of network strategies and network concepts on the overview page?

To design networks in such a way that they are precisely tailored to the specific operational and security requirements of the clients.

Q: Which technologies are referred to as ‘in detail’?

GSM-R, FRMCS, BOS, DAB+ and LST with ERTMS/ETCS.

Meeting the highest standards for reliable and secure communication

Our clients’ digital future requires state-of-the-art digital transmission networks that are precisely tailored to their needs. Whether it be railway operators, the police, fire services, emergency services or public telecommunications and broadcasting operators – we are thoroughly familiar with their specific, often safety-critical applications and the resulting high demands on security, availability and latency in data transmission. This enables us to develop network strategies and concepts that are precisely tailored to their requirements.

Our technologies in detail:

GSM-R – Global System for Mobile Communications

Supporting the migration from GSM-R to FRMCS – from strategy and planning through to roll-out, commissioning and organisational set-up.

FRMCS – Future Railway Mobile Communication System

FRMCS as a 5G-based, mission-critical and safety-critical railway communication system: network strategy, fibre-optic/IP backbone, security and project management, all from a single source.

BOS

IP migration in the BOS digital radio network: a robust fixed-line strategy, network planning and implementation for highly available, safety-critical communications networks.

DAB+

Nationwide DAB+ roll-out: site acquisition, planning, supervision of refurbishment works and partner/supplier management, right through to handover in operational condition.

LST with ERTMS/ ETCS

ETCS (including Level 2) as the key to greater safety, interoperability and capacity – with less trackside infrastructure and lower lifecycle costs.
