QUALCOMM HAS CLAIMED to be the first company to develop wireless charging technology for mobile devices with a metal exterior.
The breakthrough uses the firm's WiPower Near Field Magnetic Resonance technology, and is compliant with the Rezence standard support for wireless charging through a metal back cover.
"The ability to charge smartphones and other devices without wires offers unmatched convenience to consumers, and until now, charging a device with a metal exterior has been incompatible with wireless charging technologies," the firm said, adding that devices with metal alloy exteriors are becoming more commonplace for stronger constructions.
Steve Pazol, GM of wireless charging at Qualcomm, added: "Qualcomm's engineering advance eliminates a major obstacle facing wireless power and opens up the continued adoption of this desirable feature to a much wider range of consumer electronics and use cases."
The technology can also simultaneously charge multiple devices with different power requirements while using Bluetooth Smart to minimise hardware needs.
Qualcomm was one of the founding companies in the Alliance for Wireless Power (A4WP).
The A4WP believes that the development of magnetic resonance technology will improve the customer experience when it comes to charging, and will bring the capability into more homes and businesses over the next few years.
The alliance also said that its development of wireless charging technology will benefit industry and consumers as the specification powers broadly adopted wireless technologies such as Bluetooth Smart, "which simplifies development and manufacturing".
Qualcomm's full suite of WiPower reference designs are available today to WiPower licensees. µ
