Breaking through Cellular Signal Blockade in Energy-Efficient Buildings with Innovative Glass Antennas

Addressing the Imperative Need for Uninterrupted Indoor Connectivity in Sustainable Buildings

In the digital era, wireless connectivity has morphed from a simple convenience to an essential pillar of our daily activities. Today, between 80% and 90% of all wireless data is used indoors, and these percentages are consistently rising. By the year 2028, it’s forecasted that the average data consumption by a smartphone will catapult from 19 GB to 46 GB per month, highlighting the critical need for robust and reliable indoor wireless signals.

However, ensuring seamless indoor connectivity is not without its complexities. The push for sustainable construction, guided by standards like LEED, BREEAM, and the European Union’s Nearly Zero-Energy Buildings (NZEB) directive, has led to innovations in building materials that can inadvertently hamper wireless infrastructure. A case in point is the energy-efficient Low-Emissivity (Low-E) insulated glass.

Low-E glass, while an optimal choice for energy conservation in buildings, poses significant obstacles to indoor wireless connectivity. Its specialized coating, designed to reflect heat and promote energy efficiency, also attenuates wireless signals. The signals, often already weakened by distance and obstacles, are further reduced by Low-E glass, resulting in a 20-40 dB drop in signal strength compared to traditional windows. From a wireless link budget perspective, such a reduction is detrimental, leading to substantial signal loss and subpar connectivity.

Our patented Glass Antennas present an innovative solution to this dilemma. These virtually invisible antennas, laser-fabricated onto glass coatings, allow wireless signals to penetrate walls and glass with ease, reclaiming indoor spaces for signals that were once lost.

Smart Infrastructure and Sensor Connectivity Challenges

In the era of smart homes, a wide range of household appliances and utilities, from water and electricity meters to security systems, rely on wireless connections for data transmission. However, these devices often don’t rely on indoor Wi-Fi networks, but instead, they depend on LTE connections, which are prone to attenuation due to modern building materials.


This attenuation not only results in unreliable collection of sensor data, affecting the overall performance of the smart infrastructure, but also forces these battery-operated sensors to radiate at their maximum power levels. This excessive power usage significantly reduces the battery life of indoor wireless sensors, leading to frequent replacements and increased maintenance costs.

Our Glass Antennas are the solution to this pervasive problem. By ensuring a seamless and efficient penetration of wireless signals through glass surfaces, they enhance the reliability of smart infrastructure sensor data and extend the battery life of these crucial devices. This integration of modern construction and digital infrastructure marks a significant advancement in the smart building industry, ensuring a connected, efficient, and sustainable future.”
