AGC Automotive Europe is strengthening onboard connectivity across European rail networks through its laser-based glazing technology, developed by its Pulsaart division.

The company has now treated 50,000 train windows using its Wavethru Retrofit solution, a milestone that highlights growing demand from rail operators seeking better mobile signal performance for passengers without compromising window quality.

Wavethru Retrofit is applied directly to existing coated train windows using a precision laser process. The treatment selectively modifies the metallic coating on the glass, making it up to 300 times more permeable to mobile signalswhile maintaining the glazing’s original thermal insulation and optical performance.

This approach allows operators to significantly improve onboard connectivity without the need to replace entire glazing units, reducing both costs and downtime.

Currently, the solution is deployed with 10 rail companies across Europe, with AGC and Pulsaart continuing to collaborate with additional partners to expand its use across more fleets and routes.

Yvain Cornet, CEO of Pulsaart by AGC, described the milestone as an important step in the technology’s development.

“Reaching 50,000 treated windows is a meaningful milestone for our team and a clear indicator of market adoption and customers’ trust,” he said.

Cornet added that after four years of continuous deployment, the technology has reached a strong level of operational maturity.
