The Next Generation Of Resonant And RF Wireless Charging Technology Is Coming! Mar 16, 2018

On March 14, 2018, the AirFuel Wireless Charging Conference and Developer Forum was successfully opened at the Kempinski Hotel in Shenzhen. The event lasts for three days (March 14-16, 2018). The organizer is the AirFuel Wireless Charging Alliance, the most influential wireless charging organization in the world. This is the first time this event was held. This is also the first major event held by the AirFuel Wireless Charging Alliance in China. WST brings you an exciting review of the scene.

In 2015, Wireless Power (A4WP) merged with the Power Matters Alliance (PMA) to create the AirFuel Wireless Charging Alliance. Unlike the Qi magnetic induction technology of the WPC Wireless Charging Alliance, AirFuel technology currently includes Resonant and Radio Frequency Charge (RF) to meet different usage scenarios. AirFuel resonance technology not only has more freedom in space, but also can charge multiple devices at the same time, with a maximum charging height of up to 50 mm. AirFuel RF technology can be used for low-power charging within a few centimeters to a meter and truly free space. AirFuel members come from multiple markets around the world, covering leading brands in various fields, representing the needs of various aspects of the wireless charging value chain, from semiconductors, equipment manufacturers, to automotive and infrastructure solution providers, and other companies of various sizes.

The activity lasted for three days. The first day was a comprehensive conference. Weighing experts from Energous, EPC, IDC, Qualcomm, Huawei, WiTricity and many other organizations and companies gave wonderful speeches. The second and third days are only open to members. Developers from all over the world will gather to discuss technical details in the form of demos, seminars, case studies, etc., exchange the development status of AirFuel wireless charging technology, and help members simplify Design to better develop and market wireless charging products.

International Data Corporation (IDC) shares research results on three core areas of wireless charging consumer core requirements, continuing huge market opportunities, and the importance and standards of building a market; Sanjay Gupta, chairman of the AirFuel Wireless Charging Alliance, based on current sensing technology The limitations of customer requirements and AirFuel's role in helping different companies to apply next-generation wireless charging technologies such as Resonant and Radio Frequency (RF) are highlighted. An Energous representative demonstrated on-site how RF technology enables long-distance charging; EPC spoke about GaN Resonant solutions and showed how wireless charging can be achieved over a wide distance; WiTricity talks in depth about AirFuel resonance technology The core features and benefits of Magnetic Resonance (MRI) products have been mass produced and used in multiple markets, and share a reference design for wireless charging in automobiles.

Qualcomm demonstrated the WiPower solution and demonstrated that AirFuel resonance technology is the best technology for large-scale public wireless charging deployments (especially in the Asia-Pacific region), while emphasizing that Asia-Pacific Telecommunity (APT) has officially recommended 6.78MHz as the frequency of wireless power transmission.

The world's first mobile phone equipped with the AirFuel Resonance Wireless Charging Standard was announced at the conference. It was jointly developed by Soling Communications and TCL. The brand was initially developed as Solingphone. Adopt Qualcomm 600 series chips, equipped with Xing Cheng R1401 chip, support AirFuel resonant wireless charging. Supports wireless fast charging, twice the speed of iPhone X!

Huawei Watt Lab gave some suggestions on how to improve the performance of AirFuel technology on smart phones. In the short term, it should adopt the wireless charging scheme combining Qi and AirFuel. In the long term, a separate AirFuel solution can be achieved. Program. Based on the content of this lecture and the recent news that Huawei's new aircraft will support wireless charging, Huawei's mobile phone is estimated to use Qi-compliant AirFuel magnetic resonance wireless charging technology.

In the final part of the speech, the host opened the rumor model in response to the public's misunderstanding of wireless charging. Wireless charging is slow? AirFuel power can be very high. Is AirFuel Magnetic Resonance Technology Unsafe? We have many regulatory certifications to pass. Wireless charging and metal cannot coexist? AirFuel ignores metal foreign objects, and the mobile phone with metal back shell has no problem. AirFuel efficiency is very low? Magnetic resonance is more efficient than magnetic induction. Should the wireless charging coil be flat? AirFuel's coils are flexible and can be bent into a variety of interesting shapes. There is no AirFuel device in the market? Many, Dell, HP, Qualcomm... There are dozens of brand-name production facilities. So, AirFuel is fast, safe and efficient.

As a technology company that keeps pace with the times,Wanshuntong will apply these technologies to our products(portable charger power bank) as soon as possible.
