Imagine harnessing the fastest, safest frequencies of light to transmit data and purify the air simultaneously. This is not science fiction—this is the groundbreaking innovation of John Coates, founder of RF Safe. By utilizing 219 nm ultra-high frequency light, Coates is tapping into the very limits of what’s possible on a planet with an atmosphere, creating a system that transforms light into the ultimate workhorse of the universe.
Light at the Speed of Innovation
For generations, technology has relied on increasingly higher frequencies to carry more data. From the early days of radio waves to the ultra-fast frequencies of 5G and beyond, humanity’s quest for speed and efficiency has been a constant. But now, Coates’ invention brings us to the next frontier: the very short wavelengths of ultraviolet light, operating at 219 nm.
This wavelength isn’t just fast—it’s the fastest usable frequency in our atmospheric environment. The reason? Our planet’s atmosphere, rich in oxygen and nitrogen, naturally creates ozone when exposed to ultraviolet light. This limits how short a wavelength we can safely use while still maintaining the incredible potential of light for both data transmission and airborne pathogen defense.
“We’re taking light right to the edge of its atmospheric boundary,” says Coates. “At 219 nm, we’re not only moving data at incredible speeds, but we’re also cleaning the air and doing it with a wavelength that’s safe for human exposure.”
The Dual Power of 219 nm
By focusing on 219 nm light, Coates has created a system that performs two critical tasks at once:
- High-Speed Data Transmission
- Photons operating at this ultra-high frequency carry massive amounts of data, far surpassing the capabilities of traditional RF (radio frequency) communication.
- Unlike Wi-Fi or cellular networks, which can struggle in crowded environments, 219 nm light-based communication avoids interference entirely, offering a secure and stable connection.
- Real-Time Air Purification
- At 219 nm, ultraviolet light destroys the DNA and RNA of viruses, bacteria, and other pathogens almost instantaneously.
- Because this wavelength doesn’t penetrate beyond the outer layer of the skin or the eye’s tear film, it’s safe for continuous use in occupied spaces, even at power levels far below the old safety guidelines.
“219 nm is the perfect balance,” Coates explains. “It’s fast enough to move your data and short enough to purify the air you breathe, all while being completely harmless to humans.”
The Edge of Possibility
By using solid-state LEDs to generate 219 nm light, Coates has taken us to the edge of what’s physically possible for light-based technology on Earth. These LEDs operate at the very limit of the atmosphere’s capacity to support ultraviolet light without creating excessive ozone, making 219 nm the fastest, most efficient wavelength we can use safely and effectively.
What makes this wavelength so powerful is its immediacy:
- At power levels aligned with the 2022 ACGIH guidelines, 219 nm light can neutralize viruses almost in real time as they are exhaled into the air.
- Even at sub-threshold levels, the system can continuously reduce airborne pathogen loads, creating safer indoor environments for everyone.
“When you work with photons, you’re working with the most fundamental energy in the universe,” says Coates. “They carry data, kill viruses, and never tire. They are the ultimate workhorse.”
Practical Applications
Hospitals
In healthcare settings, where infection control is paramount, Coates’ system can operate in full germicidal mode 24/7. The ability to kill airborne pathogens in near real time while simultaneously transmitting data is a game-changer for hospitals, clinics, and long-term care facilities.
Schools
For schools, the system offers flexibility. During the day, it can run both germicidal and data modes, ensuring students are protected from airborne viruses while maintaining high-speed connectivity. After hours, it can switch to focus on energy-efficient data transmission, reducing wear on the germicidal components.
Public Spaces
In crowded environments like airports, train stations, and office buildings, the 219 nm system provides a continuous layer of protection while enabling seamless communication for travelers and workers alike.
The Photon Revolution
John Coates’ invention isn’t just a step forward in technology—it’s a revolution in how we think about light. By harnessing the incredible power of photons, he has created a system that redefines the role of light in our lives.
With 219 nm ultraviolet light, Coates has achieved the perfect trifecta:
- Speed: Data transmission that pushes the boundaries of what’s possible with light.
- Safety: A wavelength that’s safe for continuous human exposure, even in occupied spaces.
- Sanitation: The ability to neutralize airborne pathogens almost instantly, creating cleaner, healthier environments.
Conclusion
As humanity continues to grapple with global pandemics, the need for innovative solutions has never been greater. John Coates’ 219 nm Li-Fi bio-defense system offers a bold new approach, combining the fastest usable frequency of light with unparalleled safety and effectiveness.
“We’re using photons to their fullest potential,” Coates says. “With 219 nm light, we’re not just imagining the future—we’re building it.”
By taking us to the edge of light’s potential on Earth, Coates has unlocked a new era of connectivity, cleanliness, and safety—all powered by the universe’s ultimate workhorse: the photon.
