WAVETHRU™ Retrofit: Over 4,000 Upgraded Windows Already in 2025

At Pulsaart by AGC, we are pleased to share an exciting milestone in our mission to improve rail connectivity in Europe. More than 4,000 train windows have already been treated with our WAVETHRU™ Retrofit solution in 2025 — and the year has only just begun.

This achievement is more than a number. It represents the growing confidence that leading European rail operators place in our technology. Our laser-based glazing treatment allows train windows to become permeable to mobile signals while preserving the thermal insulation performance of modern glass. It offers a fast, non-intrusive, sustainable, and cost-effective way to enhance mobile connectivity without replacing existing windows.

As passenger expectations rise for seamless mobile connectivity during travel, WAVETHRU™ Retrofit is helping operators meet the challenge. By improving signal penetration inside trains, we support rail operators in offering a more connected, comfortable, and future-ready experience.

We are proud of the trust placed in our solution and grateful for the strong partnerships driving this momentum. With more deployments on the horizon, Pulsaart by AGC remains committed to enabling smarter, more connected rail travel across Europe.
