BELLEVUE, Wash., Dec. 1, 2016 /PRNewswire/ -- Ossia, the company behind the Cota™ remote wireless charging technology, today announced that while powering a device remotely, Cota was proven to pass the same safety thresholds for Wi-Fi and Bluetooth operations as the FCC requirements for safety and interference, a level of performance necessary to advance the approval process. Cota's remote wireless charging technology met the permissible exposure rates set by both U.S. and global standards.
The company, which recently announced a newly allowed patent that covers pulsed power as required at the receiver(s), continues to set the standard in the fast-growing remote wireless charger industry, licensing its technologies to top-tier OEMs, competitors and prestigious research universities. Ossia's progress in passing a key requirement in the approval process demonstrates its ability to shape the state of the art in the remote wireless charging industry. The exposure and interference test was conducted by 3 rd 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."
