Wireless Charging Organizations A4WP And PMA Reveal Their Brand New Merged Identity: AirFuel Alliance

Earlier in January of this year, two wireless charging organizations announced a plan to merge their forces in order to combat the monstrous market leader Qi. And now Power Matters Alliance (PMA) and the Alliance For Wireless Power (A4WP) seem to have finally combined their assets and member lists to create a new identity: AirFuel Alliance.

PMA, the most famous of the two organizations, uses magnetic induction to achieve wireless charging and has been commercialized in Duracell's Powermats and certain variants of the LG G3 and the Samsung Galaxy S6. A4WP is a more obscure player since its resonance-based charging protocol hasn't been seen in consumer products yet.

Qualcomm Figures Out How To Wirelessly Charge Phones With Metal Cases

The Galaxy S6 has wireless charging. The HTC One M9 does not. There's a pretty good reason for this: metal interferes with the current methods for wireless charging, so you can't have your fancy metal phone and charge it (wirelessly) too. Engineers at Qualcomm have a solution to that, at least according to the company's latest press release. It's a newly-announced functionality of the existing Rezence wireless power standard, which is different from Qi and PMA.

According to Qualcomm, the Rezence/WiPower standard operates at a frequency that's more forgiving of extra material in between the contact and the receiver, including everything from metal to empty space.

Wireless Charging Organizations PMA And A4WP Merging To Better Combat Market Leader Qi

Ubiquitous Wireless Power Fast Becoming A Reality As Samsung, Qualcomm And Others Unite To Develop A New Standard

Amongst the smorgasbord of features Samsung announced for its newest flagship device the Galaxy SIII, the wireless charging accessory seemed the most no-brainer. Wireless power has been a dream for almost everyone, but aside from short-lived products, such as the Touchstone that was available for Palm's Pré phones, they have not really become a reality.

Today Samsung and Qualcomm, together with a group of other technology companies, announced a new initiative that aims to promote the "global standardization of a wireless power transfer technology". The appropriately named "Alliance for Wireless Power (A4WP)" will help create an affordable wireless charging solution for a range of consumer electronic devices, from low power ones, such as Bluetooth headsets, to battery draining tablets.
