What is the nu glass Project?
nu glass is revolutionizing indoor connectivity by transforming coated windows into RF-friendly glass. Imagine turning those frustrating dead zones inside trains and buildings into fully connected spaces. That’s exactly what nu glass does. Using a patented laser treatment, this Swiss EPFL spin-off makes coated glass permeable to mobile signals without compromising the glass’s insulation, strength, or aesthetics. The process is done onsite, quickly and cleanly, with no need for unmounting, drilling, or wiring. It’s a passive, maintenance-free solution that lasts for the entire lifetime of the window.
Main Benefit: Boosting Indoor Signals Like Never Before
Here’s the deal: nu glass can boost indoor signals by up to +30 dB. That’s not just a little improvement—it’s up to 1000 times stronger than before. Check out these key facts:
- Signal strength increased by up to +30 dB
- Compatible with all standards: 3G, 4G, 5G, Wi-Fi, IoT, and MIMO
- No maintenance or upgrades needed after treatment
- 2 to 5 times more cost-effective than traditional repeaters
- Onsite treatment takes just 20–25 minutes per window
How Does the Technology Work?
The magic lies in an invisible laser treatment delivered by a trained team using an in-house robotic system. This system ensures precision and consistency, making the coated glass permeable to radio frequencies. The best part? The glass keeps all its original qualities—insulation, strength, and looks—while suddenly letting signals flow freely. It’s a clever, passive solution that doesn’t require any upgrades or maintenance down the line. Plus, it’s all done onsite, so no hassle or downtime.
Compatibility and Future-Proof Connectivity
nu glass doesn’t just work with today’s tech—it’s built for the future. Whether it’s 3G, 4G, 5G, Wi-Fi, IoT devices, or MIMO systems, this solution plays nicely with every standard. This means buildings and trains treated with nu glass are ready for whatever connectivity demands come next. No need to worry about obsolescence or costly upgrades. It’s a future-proof investment in seamless indoor connectivity.
Cost-Effectiveness and Practical Advantages
Compared to traditional repeaters, nu glass is a game-changer in terms of cost and convenience. It’s 2 to 5 times more cost-effective, delivering better performance without the need for extra infrastructure. Since the treatment is passive and maintenance-free, it saves money and effort over the long haul. And because the process is quick and onsite, it minimizes disruption—no drilling, no wiring, no unmounting. Just a smart, invisible upgrade that keeps spaces connected.
