It's all about the proliferation of resonant charging technology, says Qualcomm.
Qualcomm has said it has chosen to join the Wireless Power Consortium (WPC), a rival organization to the Qualcomm-founded Alliance for Wireless Power (A4WP), to encourage the broad adoption of resonant and loosely coupled wireless charging.
The news that Qualcomm was backing two industry organizations emerged when WPC chairman Menno Treffers published a blog announcing that Qualcomm and Verizon Wireless had joined the organization (see Qualcomm Move Raises Wireless Charging Questions).
Qualcomm's WiPower technology is in line with A4WP v1.0 which specifies magnetic resonance technology that is capable of simultaneous charging multiple devices and is flexible with regard to the positioning of devices on a charging platter. A4WP has the backing of co-founders Qualcomm and Samsung, Intel, which has done its own R&D on resonant magentic charging technology and more than 50 other companies. However, WPC is an older organization with more members and more mature standards.
In a statement supplied to EE Times Qualcomm said: "Qualcomm aims to provide the opportunity to standardize around a single global implementation of resonant wireless power technology by working more closely with other industry innovators. The WPC has previously announced plans to move toward a resonant/loosely coupled wireless power similar to that being developed by Qualcomm WiPower and the A4WP. By joining the WPC, Qualcomm can bring its expertise in resonant wireless power to bear and to look toward harmonization across wireless power standards."
Qualcomm added that its status as a founder and board member at A4WP was unaffected by its decision to join WPC. "A4WP represents the most mature and best implementation of resonant charging. It is Qualcomm's belief that the WPC can leverage the work in resonant wireless charging that has been completed by the A4WP."
Qualcomm also said that it started shipping A4WP evaluation kits to companies in March 2013 and that it expects products incorporating A4WP-compliant wireless charging to begin shipping early in 2014.
