Future Railway Mobile Communication System (FRMCS) has been set up to provide railways with a standardized, future-proof communication solution capable of supporting advanced rail operations and services. FRMCS builds on 3GPP-based 5G standalone and mission-critical (MCX) architectures to support the new ETCS as a replacement for GSM-R. But the path towards FRMCS is way more than a straight-forward technology upgrade. The development of FRMCS is a testament to the power of collaboration among diverse stakeholders across the railway ecosystem.In this episode, we're joined by Marta Fontecha and Raquel Frisa from Teltronic (www.teltronic.es/en/transport/), who share first-hand insights, from lab trials to field pilot deployments like their upcoming high-speed trial, in collaboration with the Spanish railway operator Adif.  The discussion highlights the key learnings to make FRMCS the backbone of safer, more efficient railway transportation networks.
