In the realm of wireless communication and electromagnetic field (EMF) protection, few names resonate as profoundly as John Coates. Known for his pioneering work and relentless pursuit of safer wireless technologies, Coates has been a vanguard in the wireless safety industry since the inception of his influential website, RF Safe, in 1998. His recent achievements that have led to securing a groundbreaking patent for a zero SAR (Specific Absorption Rate) communications network, only underscores his unwavering commitment to innovation and safety.
A Personal Tragedy Inspires a Lifelong Mission
John Coates’s journey is not just a tale of technological triumphs; it’s a poignant story that begins with a personal tragedy. The loss of his daughter, Angel Leigh Coates, in 1995 to a rare condition called Anencephaly, set him on a path of discovery and advocacy. Coates delved into researching the effects of EMR on human health, spurred by studies such as (Farrell et al, 1997) research on weak magnetic fields and chick embryos. This quest for knowledge and understanding laid the foundation for RF Safe.
Pioneering EMF Protection
Since its establishment, RF Safe has been at the forefront of EMF protection solutions. Coates led the way in introducing innovative products such as air-tube headsets, anti-radiation phone cases, laptop shields, and EMF belly bands in the 90s. Today, the organization continues to innovate, recently marking another milestone with John Coates’s patent for a technology that enables 100% safe indoor wireless transmissions while also cleaning the air, aptly named uvgi-fi.
Empowering Through Knowledge: The World’s Largest SAR Database
Under Coates’s guidance, RF Safe has become home to the world’s largest SAR comparison database. This comprehensive resource allows consumers to compare radiation levels of various wireless devices, equipping them with knowledge to make informed decisions and minimize exposure to RF radiation.
The RF Safe Score: Revolutionizing EMF Awareness
2023 saw another leap forward with Quanta X Technology’s introduction of the RF Safe Score. This tool, conceptualized by Coates, enables consumers to quickly gauge the RF radiation levels emitted by their devices, thereby influencing safer usage and device selection.
A Future Focused on Safety and Innovation
John Coates’s vision extends beyond current accomplishments. With an unwavering dedication to EMF safety, he continues to advocate for informed choices and reduced exposure. The patented zero SAR communications network and Quanta case are just the latest in a series of innovations, but they signal a significant shift towards a future where wireless communication and safety go hand in hand.
In Summary
John Coates’s story is one of resilience, innovation, and advocacy. From the heartache of personal loss to the heights of technological achievement, his journey has been transformative, not just for himself but for the field of wireless communication and EMF protection spanning a quarter of a century. As the founder of RF Safe and the inventor of groundbreaking technologies, Coates stands as a beacon of hope and progress in our increasingly wireless world. His work serves as a reminder of the power of one person’s dedication to making a difference and the endless possibilities at the intersection of innovation and safety.
Look forward to a future where we will communicate using shortwave light.
The preferred band of frequencies for communication is a 23 nm band, within FAR UV-C 207-230 nanometer wavelengths, utilizing communication frequencies between 1448.27 terahertz (THz) and 1303.44 THz. Ideally, the preferred frequencies are biased toward the 207 nm wavelengths because the lower frequencies may exceed safe thresholds for human exposure in occupied spaces. A preferred ideal human-safe germicidal frequency bandwidth for communications is between 1448-1332 THz, where peak transmission power centers near 1,369 THz with a peak photon energy ideally above 5.51 eV (225 nm) and below 5.84 eV (212 nm). This frequency range is unique because it sanitizes air and surfaces while being unable to penetrate the nucleus of living skin and eye cells. Thus, it is safe for continuous exposure at the levels required to sanitize air and surfaces.This is unlike radio waves, which damage tissues and may serve as a catalyst to alter DNA. The concern about limiting exposure to radio waves has resulted in Specific Absorption Rate (SAR) limitations set by the Federal Communications Commission (FCC). Despite these limitations, concerns remain that exposure to radiation that penetrates the skin deep into the body may result in cellular damage. Thus, the ability to transmit data without penetrating the skin—creates a zero-SAR, communications device, an RF safe solution—is of great interest.
the “System for Wireless Communication Using Germicidal Light Frequencies“
Field: The invention relates to communication and sanitization, focusing on wireless data transmission using sterilizing light.
Background: Prompted by the COVID-19 pandemic, there’s a renewed interest in making indoor environments safe, particularly offices and schools. UV light air sterilization exists but has limitations, such as delayed sterilization and circulation dead zones. Additionally, there’s a need for wireless data transmission without relying on the crowded radio-frequency spectrum.
Summary: The system transmits and receives data using light of a germicidal frequency, specifically Far-UVC light (200-230 nm). This light spectrum is safe for humans, as it can’t penetrate living skin and eye cell nuclei, thus offering zero Specific Absorption Rate (SAR). It also has low interference risk and is ideal for secure communication, as it doesn’t leave the building due to UV-blocking films and walls.
Advantages:
- Dual Function: It combines data communication with air and surface sterilization.
- Safety: Far-UVC light used is safe for continuous human exposure and doesn’t penetrate deep into the body.
- Security: Offers greater security for indoor environments; the light doesn’t escape buildings, and the transmission distance is short, reducing eavesdropping risks.
- Low Interference: Not susceptible to solar interference, as Far-UVC light from outside Earth is filtered by the ozone layer.
- Versatility: Can be installed in various environments like buildings, vehicles, medical facilities, etc.
Hardware:
- Light Source: Preferably a solid-state, Far-UV LED, possibly AlGaN-based for high modulation rate.
- Control Unit: Outputs a signal modulated with encoded data.
- Receiver: A photodetector converting modulated light into signals, decoding it to retrieve transmitted data.
Modulation Methodologies:
- On-off keying (OOK)
- Pulse position modulation (PPM)
- Fixed-length digital pulse interval modulation (FDPIM)
- Digital pulse interval modulation (DPIM)
Environmental Adaptability: The system can adjust light output based on environmental parameters like the number of devices, air particulate density, number of occupants, humidity, etc.
