Problem
Indoor environments such as office buildings, train carriages, and public venues often rely on extensive antenna and repeater installations to provide reliable mobile and IoT connectivity. Deploying and maintaining this hardware is costly, disruptive, and can compromise safety and aesthetics.
Solution
Nu Glass offers a patented laser treatment that makes existing glass surfaces permeable to mobile and IoT signals while preserving the glass’s optical and structural properties. The technology is applied as a retrofit to windows and façade panels, requiring no dismantling, no service interruptions, and no additional safety hazards. Treated glass becomes a passive high‑performance data transmission point, reducing the need for separate repeaters, antennas, and cabling. Installation integrates with routine maintenance schedules, allowing operators to upgrade connectivity with minimal labor and downtime. The result is a seamless, low‑maintenance indoor network that supports high‑capacity mobile traffic for large numbers of users.
Target Audience
Primary customers are building owners, facility managers, and transportation operators (e.g., train and subway systems) seeking to improve indoor mobile and IoT connectivity while minimizing infrastructure costs and disruption.
