We are Glassdio
We are a Hong Kong deep-tech company built on long-term research from City University of Hong Kong, backed by granted patents and additional patent-pending technologies in glass‑concept antenna design. Our team brings together a distinguished professor, a entrepreneurial microwave industry experts in microwave products, and together with energetic young engineers — providing a reliable foundation for collaboration. Powered by unique solution approaches and our proprietary, novel Glassdio materials, our 5G glass‑concept antennas deliver superior real‑world results—dramatically improving transceive performance for both handheld and stationary 5G devices.
Our business strategy embeds environmental protection and social responsibility as we design, manufacture, and supply innovative, compact, and cost‑effective products with a sustainable footprint—plus the added benefit of elegant, transparent aesthetics.
Why Choose Us?
Fifth-generation (5G) networks are widely deployed. The 3.5 GHz mid band is the most cost effective and broadly adopted spectrum, delivering higher data rates and lower latency than 4G while supporting high capacity and dense access.
However, 3.5 GHz experiences higher path loss, greater blockage sensitivity, and reduced building penetration, especially in rainy days. Even the lowest loss entry path—windows—often adds several decibels of loss, depending on glazing and incidence angle and distance apart to window.
As a result, users may see reduced data rates or coverage blind spots, including inside cars, buses, and trains.
Mass produced 5G devices (smartphones, tablets, CPE, 5G network camera) offer low cost and high performance. Beyond personal communications, they serve as compute nodes, Wi Fi/5G hotspots, control interfaces, and UAV controllers, enabling rapid, cost effective prototyping without bespoke hardware.
There is a strong need to improve reception and extend coverage for these devices, especially in blind spot areas, to maintain reliable operation—particularly in rainy conditions. Our 5G external antennas and lens antenna series can fit different situation to improve the signal receptions.
