The exposure and interference test was conducted by 3rd party testing lab, Northwest EMC, which provides a full range of wireless testing services, including EMC compliance for leading technology and electronics innovators. The lab conducted extensive testing and found that Cota delivered up to one watt of power successfully while maintaining FCC exposure requirements for safety and interference.
How Cota Works:
Cota wireless power is comprised of three main components: a transmitter that sends power, a receiver that accepts the power at the source and a cloud software system to manage it all. A Cota-powered device (receiver) emits an omnidirectional low power beacon signal in the Wi-Fi 2.45GHz spectrum signal, bouncing off walls, floors and ceiling, but not passing through people or animals (organic matter). The Cota charger (transmitter) receives the incoming beacon signals and retro-directively sends power back via the same Wi-Fi 2.45GHz spectrum precisely along the paths of the incoming beacon signals; this return signal avoids obstructions such as people, limiting RF radiation absorption and enhancing safety.
These focused RF waveforms combine at the exact receiver antenna geometry and are converted into power by the Cota receiver to charge the device’s embedded battery. This two-step process is repeated one hundred times per second. This critical feature protects humans from any exposure as the transmitter never delivers power unless it has received a beacon signal from a receiver. Simply, if there is no beacon, there will be no power sent. The way this technology was invented and built makes it inherently safe, thus passing regulatory standards.
“The test results establish Cota’s ability to safely deliver wireless power remotely while maintaining user safety and device interference standards not only in the U.S. as regulated by the FCC, but according to standards established by other governing bodies worldwide,” said Hatem Zeine, founder and CTO of Ossia and creator of the Cota technology.
“This was a key milestone required by matching the accepted safety of Wi-Fi and Bluetooth, Cota builds on that trust established by the FCC and other government bodies worldwide. Soon, we will never have to charge our personal devices, run cables to IoT devices or replace batteries again. Enabling the unrestricted growth of IoT and enabling big data solutions to help us with our health, safety, productivity and entertainment. This is a great win for the company’s licensees as it reduces the hurdles on integration of Cota into their devices and systems.”
Ossia’s Cota technology safely delivers targeted power to devices, allowing users to keep devices charged and ready for use without plugging them in or placing them on charging pads. It provides the convenience of Wi-Fi to deliver data and power to devices, reaching devices around corners and over obstructions without requiring a direct line of sight.
As a leader in remote wireless charging, Ossia works with a variety of strategic partners and product developers to explore commercial and consumer applications for its wireless charging technology. Learn more about Ossia at www.ossia.com.
