Railway Dedicatied Networks (RDN) from Kapsch CarrierCom:
Exceeding GSM-R standards, ready for the Next Generation

To operate effectively and protect passengers and staff, rail operators need reliable, future-proof, secure network infrastructure. As the ERTMS agenda advances, railway communications must also be totally interoperable across international borders.

Kapsch CarrierCom’s end-to-end Railway Dedicated Network (RDN) solutions support the entire range of railway voice and data communication requirements. Performance is guaranteed at speeds exceeding 500 km/h (310 mph) without any communication loss, ensuring the safety of passengers and staff.

We have been designing, building, deploying and supporting RDN solutions based on the GSM-R standard for nearly 20 years. Today, we are the industry leader, providing communication for around 80,000 kilometres of railway tracks across Europe, Africa and Asia.

Key benefits of our RDN solutions include:
