Train Windows Become 5G Antennas

Rail operator JR Central will install windows with microscopic antenna wires woven into the glass (from AGC) to maintain line‑of‑sight 5G connectivity at up to 285 km/h, paired with on‑train Wi‑Fi routers; the operator will also trial personalized noise‑cancelling ‘suites’ using NTT’s sound‑inversion tech. The move treats a moving vehicle’s physical surfaces as permanent telecom infrastructure rather than temporary endpoints. — Embedding network hardware into public‑transport infrastructure changes who controls connectivity (rail operators, suppliers), raises privacy/surveillance and commerce questions, and signals a premiumization of onboard services that could widen digital‑access inequalities.
