• Resonant charging works by creating a wireless transfer of electrical energy between two coils, tuned to resonate at the same frequency. Based on the principles of electromagnetic coupling, resonant-based chargers inject an oscillating current into a highly resonant coil to create an oscillating electromagnetic field. A second coil with the same resonant frequency receives power from the electromagnetic field and converts it back into an electrical current that can be used to power and charge devices.

• Radio frequency (RF) wireless charging technology 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. There are two main categories of RF wireless charging: Near Field and Far Field.

AirFuel Alliance’s mission is to bring a diverse base of interoperable products to the global market that deliver the best wireless charging experience for consumers. The organization membership is made up of leading technology and consumer electronics companies. Its board of directors includes representatives from Dell, Duracell, Energous, EPC, ONSemiconductor, PowerSphyr, Qualcomm, Samsung Electronics, Starbucks and WiTricity.

The AirFuel Developer Program includes online and hands-on support to help foster innovation and create a broader ecosystem of commercialized products and public infrastructure solutions, beginning with Resonant technology. It will incorporate several of AirFuel’s existing development initiatives, such as product testing and certification, with new developer support and resources that make it faster and more cost-effective to certify and bring to market Resonant and RF-based solutions.

AirFuel has also created a new, annual AirFuel Developers Forum. The three-day event (day one is open to the public; days two and three are for AFA members) takes place 14-16 March 2018 at the Kempinski Hotel Shenzhen in Shenzhen, China and features speakers from Energous, EPC, Huawei, IDC, Qualcomm, and WiTricity, among others.

The first Developer Forum is being held in China to underscore the momentum for AirFuel Resonant technology in that region. AirFuel has seen a significant increase in Resonant product and infrastructure development throughout Southeast (Mainland) China and Taiwan and there are tens of thousands more expected in 2018. By 2021, projections show Resonant adoption growing more than 240%, with major expansions in hospitality, dining, travel and automotive industries.
