Nu Glass SA

Nu glass enables seamless mobile connectivity in trains and buildings by making existing windows transparent to mobile signals. Our proprietary on-site laser technology, developed at EPFL, modifies glass surfaces to allow mobile frequencies to pass through, without removing or replacing the windows. This sustainable and cost-efficient solution dramatically improves network access for millions of users while reducing the need for energy-intensive telecom infrastructure. Nu glass targets major markets in telecommunications, transport, and real estate, helping operators, passengers, and building occupants stay reliably connected everywhere.
