Samsung and Qualcomm Inc have joined other technology leaders such as Ever Win Industries, Gill Industries, Peiker Acustic, SK Telecom and Powermat Technologies to form Alliance for Wireless Power (A4WP)

A4WP  the independently operated organisation’s mission is to promote global standardisation of a wireless power transfer technology that offers spatial freedom, to develop product testing, certification and regulatory compliance processes, and to foster industry dialogue with regulators on wireless power policy development. 

“Qualcomm is delighted to be involved in this dynamic initiative to set the standard for wirelesspower,”said (right) Derek Aberle, executive VP and Group President, Qualcomm. “Going forward, we hope to welcome additional companies and organisations who are looking to contribute towards setting the best possible standard for wireless power.”

"A4WP will accelerate the commercialisation of this technology and will contribute to expanding its market. ," said (left)  executive VP KiHo Kim, head of Digital Media & Communications R&D Center, Samsung Electronics.

The alliance is targeting a broad base of consumer electronic devices to establish a worldwide wireless power technology ecosystem.

The A4WP will focus on a new wireless power transfer technology that provides spatial freedom for charging of electrical devices in cars, on tabletops and for multiple devices simultaneously.

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.

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.

The A4WP is open to new members and welcomes participation from vendors in all segments of the potential ecosystem, including: handheld devices, consumer electronics, semiconductor products, automotive, furniture, test equipment, cellular operators, and retail.

According to the analyst firm IMS Research, shipments of wireless power enabled devices are projected to surpass 100m by 2015. Research manager (right) Jason de Preaux comments, “Wireless power has the potential to increase convenience and improve the user experience in consumer devices like mobile phones by untethering the charging process.

"For these benefits to be realised, wireless power infrastructure must be deployed to enable wireless charge points in the home, at work, or while traveling without concern for compatibility. Industry alliances will play a critical role in developing this infrastructure.”
