U.S. Patent and Trademark Office Approves Revolutionary System for Transmitting Data While Improving Air Quality

John Coates Secures Groundbreaking Patent for Germicidal Light Frequencies in Wireless Communication

John Coates, the founder of RF Safe, has recently obtained a patent from the United States Patent and Trademark Office (USPTO) for a pioneering system that uses germicidal light frequencies in wireless communication. The patent, application number 17/497,011, was filed on October 8, 2021, and granted on March 28, 2023. This innovative technology has the potential to reshape the future of wireless networks by offering a safer and more efficient alternative for data transmission while improving air quality in indoor environments.

The UVGI-Fi System: A Revolutionary Approach to Wireless Communication

Coates’ patented system, referred to as UVGI-Fi (Ultraviolet Germicidal Irradiation-Fidelity), combines wireless communication with germicidal light frequencies, specifically Far-UVC light. The system communicates data using Far-UVC light of germicidal wavelengths, employing solar-blindin data-carrying frequencies in the terahertz (THz) range to provide a UVGI function.

This unique approach allows the UVGI-Fi system to transmit and receive data while simultaneously cleaning the air by inactivating harmful microorganisms, such as bacteria, viruses, and fungi. As a result, the technology can potentially improve indoor air quality and reduce the transmission of airborne diseases.

Implications and Potential Applications of the UVGI-Fi System:

The UVGI-Fi system represents a groundbreaking advancement in wireless communication technology, addressing two pressing concerns in modern society: the potential health risks associated with EMF radiation exposure and the growing issue of poor indoor air quality.

Possible applications for the UVGI-Fi system span across various industries, including healthcare, education, transportation, and residential settings. In hospitals, for instance, the technology could be used to improve air quality, reduce the spread of infections, and enhance patient outcomes. In schools and offices, UVGI-Fi could contribute to a healthier environment by reducing the transmission of airborne illnesses and enhancing overall well-being.

Furthermore, the UVGI-Fi system’s ability to transmit data without relying on traditional wireless networks reduces the risk of EMF radiation exposure, making it a safer alternative for data transmission.


The approval of John Coates’ UVGI-Fi patent by the U, demonstrates his commitment to developing innovative solutions that promote public health and enhance daily life. As the world continues to rely heavily on wireless technology, the demand for solutions that protect users from EMF radiation and improve overall well-being will only grow. By combining wireless communication with germicidal light frequencies, the UVGI-Fi system offers a safer and more efficient alternative for data transmission while simultaneously improving air quality in indoor environments. As RF Safe continues to lead the way in EMF protection solutions, the company’s groundbreaking technologies will play a crucial role in shaping a safer, healthier future for all.
