Delivering ‘Power at a Distance’ with AirFuel RF 

by Kathy Van Buskirk

If you’ve started thinking about your New Year’s resolutions – considering adding this one to your list: start the new year with less wires and more charge!  AirFuel next-generation wireless charging technologies, which include AirFuel Resonant and AirFuel RF, are providing an improved wireless charging experience for consumers and businesses around the globe, and moving wireless power beyond the many limitations of Inductive charging.

We’ve got exciting news to share from one of our AirFuel RF members on just how improved an experience we’re talking about, but before we do here’s a quick guide to RF for those RF newbies: AirFuel RF (or Radio Frequency) wireless charging is unique in that it uses electronic waves or radio frequencies vs. magnetic fields to charge a device. An RF transmitter transmits RF waves and a receiver embedded within a device picks them up, converts them into electricity, and powers the device.  RF can power devices at a distance ranging from a few centimeters to a few meters. This wireless charging technology offers several distinct advantages, including spatial freedom (up to 15 ft of wireless charging), flexibility of integration (can be put in very small devices), multi-device charging, and the elimination of an installation in walls or furniture.

So what’s the exciting news? One of our AirFuel board members, Energous Corporation, this week announced the Federal Communications Commission (FCC) certification of its first-generation WattUp Mid Field transmitter, which sends focused, RF-based power to devices at a distance. This is the first FCC certification for power-at-a-distance wireless charging under Part 18 of the FCC’s rules.

The company’s WattUp Mid Field transmitter can deliver power via radio frequency (RF) energy to WattUp-enabled electronic devices at a distance of up to three feet. WattUp is highly scalable and automatically charges devices, as needed, until they are topped off. Similar to WiFi, the WattUp ecosystem ensures interoperability between receivers and transmitters, regardless of the manufacturer, making the entire ecosystem flexible and accessible for consumers and manufacturing partners.

Check out more on the news here (Energous FCC News) and come see the Energous technology, and many other great AirFuel Resonant and AirFuel RF technology demos, live at the AirFuel Alliance booth (#40140) at CES starting January 9th.
