Qualcomm Inc. and Samsung Electronics Co. Ltd have formed the Alliance for Wireless Power (A4WP), an organization that will promote global standardization of wireless power transfer for the charging of consumer electronic equipment.

The A4WP will focus on a new wireless power transfer technology that provides spatial freedom for charging electrical devices in cars, on tabletops and for charging multiple devices simultaneously, Qualcomm said. Other companies who will join the alliance include: Ever Win Industries, Gill Industries, Peiker, Powermat Technologies and SK Telecom.

"Qualcomm is delighted to be involved in this dynamic initiative to set the standard for wireless power. WiPower Technology by Qualcomm is ideally suited for a forum like the A4WP. As a leader in delivering enabling technology solutions, Qualcomm is helping to define the next-generation consumer electronics experience," said Derek Aberle, executive vice president at Qualcomm, in a statement.

The benefits of this wireless power approach include: a transmitter and receiver antenna design that is easily implemented, a simple wireless power control system, and the ability to transfer power through non-metallic surfaces, said Qualcomm. The A4WP expects to achieve this capability without the need for costly multi-coil repeaters, which are required for other systems. A single specification is envisioned that will address simultaneous charging of multiple devices ranging from very low power products, such as Bluetooth headsets, to today's most sophisticated tablets.

"As a founding member of A4WP, Samsung is committed to supporting standardization of wireless charging technology boasting spatial freedom, contributing to the eco-system, and exploring possibilities of a variety of services," said executive vice president KiHo Kim, head of digital media and communications R&D center at Samsung.
