Gosselies, Belgium | March 11, 2026 — Pulsaart by AGC, a Belgian innovation initiative within AGC Automotive Europe, today announces a major milestone for passenger connectivity in rail: 50,000 train windows have been treated with WAVETHRU™ Retrofit across Europe.
WAVETHRU™ Retrofit is a laser-based glazing treatment applied to existing train windows. The treatment makes coated glazing more permeable to mobile signals while preserving the window’s essential functions, including thermal insulation and optical performance. In operational deployments, the unique glass treatment increases mobile signal coverage inside the train car by up to 300 times, without altering the passenger’s view through the window. Performance is validated through pre- and post-treatment RF measurements, complemented by on-train quality checks.
The service is currently deployed with 10 rail companies across Europe, and Pulsaart by AGC is working with partners to expand deployments further. Some deployments remain confidential under customer agreements; Pulsaart by AGC therefore does not disclose customer names or deployment geographies for all programs.
While widely adopted in rail, AGC applies the same principle to other glazing environments where signal penetration is constrained, including buildings equipped with high-performance coated glass.
“Reaching 50,000 treated windows is a meaningful milestone for our team and a clear indicator of market adoption and customers trust. Over the last 4 years, we have reached a significant maturity level with continuous operation,” said Yvain Cornet, CEO of Pulsaart by AGC. “Rail operators want measurable improvements in onboard connectivity, but they cannot compromise on passenger comfort or window performance. WAVETHRU™ Retrofit delivers both while reducing costs compared to expensive window replacement. We value the trust of our partners across Europe and we remain focused on scaling deployments with additional rail companies in new countries.”
