LONDON – Intel has joined the Alliance for Wireless Power (A4WP) consortium and taken a seat on the board of directors along with Broadcom, Gill Industries, IDT, Qualcomm, Samsung Electronics and Samsung Electro-Mechanics.
The move will put weight behind A4WP which is a rival standards organization to the Wireless Power Consortium (WPC), seeking to provide wireless charging for portable consumer electronics devices, including, smartphones, tablet, netbook and laptop computers.
WPC was the first to market and claims as many as 8.5 million products have shipped using its Qi technology, some based on chips announced last fall by Texas Instruments. Intel demonstrated its own technology.
A4WP, which specifies the use of magnetic resonance technology, is capable of simultaneous charging of multiples devices and the flexible positioning of devices and a charging platter.
"Intel believes the A4WP specification, particularly the use of near field magnetic resonance technology, can provide a compelling consumer experience and enable new usage models that make device charging almost automatic," said Navin Shenoy, general manager of the mobile client platform division at Intel, in a statement issued by A4WP.
The A4WP mission includes development of industry specifications for submission to national and international standards development organizations, management of an A4WP certification program, including consumer-recognizable certification logo and the coordination with national and international regulatory agencies regarding policy and compliance.
I'm curious about this statement: "A4WP, which specifies the use of magnetic resonance technology, is capable of simultaneous charging of multiples devices and the flexible positioning of devices and a charging platter."
How is this different than what WPC is doing?
A4WP is making the distinction between direct induction and magnetic resonant induction where the two coils are tuned to resonate at a set frequency.
I understand this has benefits for efficiency of energy transfer.
