VIAVI remains committed to supporting GSM‑R and its transition toward FRMCS through 2040 by providing long‑term expertise, technical assistance, and maintenance services. The company will continue dedicating professional services, support teams, R&D resources, and in‑house GSM‑R/ETCS skills to ensure reliable operation as GSM‑R, a 20‑year‑old 2G technology, coexists with newer systems. With GSM‑R expected to operate alongside FRMCS until around 2040, maintaining and supporting these networks is essential. VIAVI’s long-term commitment ensures stable performance and continuity for railway operators throughout the migration period.
