Wireless charging consortium launches Rezence, its consumer brand
It plans to showcase wireless charging tech at next month's CES
Computerworld - The Alliance for Wireless Power (A4WP), a consortium founded by Qualcomm and Samsung, has launched the consumer brand for its future products: Rezence.
Along with the new brand and a logo, the A4WP consortium has developed a certification program that allows developers and product makers to verify their products meet the wireless charging's specifications.
"One of the benefits of this technology is that we can charge products that range in power from 3.5 watts to 16 watts and we can charge multiple devices on one charger," said Gary Matos, strategic marketing director for A4WP.
Matos said Rezence-certified chargers should be able to provide a charge in about the same time as a wired device.
"There's always some efficiency loss with wireless charging, so to achieve the same charging time, we may have to put more power through it," Matos said.
Because the Rezence specification uses electromagnetic resonance technology, it is able to charge through objects as well as charging devices placed directly on a charging mat, said Geoff Gordon, chair of marketing for A4WP.
The A4WP plans to showcase certified wireless chargers and mobile products at the upcoming Consumer Electronics Show in Las Vegas.
The organization also held its last plugfest, an event for product manufacturers to initially test their devices with the specification, this week.
The A4WP now has 70 members including Broadcom, Delphi, Fairchild Semiconductor, Haier, Intel, LG Electronics, Qualcomm, Samsung Electronics, SanDisk, TDK and Texas Instruments.
The A4WP claims that its electromagnetic resonance technology enables users to charge devices at a distance; the group also contends that its system offers a larger charging field than rival platforms. With A4WP technology, the organization claims, multiple devices, such as a tablet and a smartphone, could be placed on one pad and charged at the same time.
A4WP's biggest competitor in the wireless charging arena is the Wireless Power Consortium (WPC), which developed the Qi (pronounced "chee") standard. The Qi specification enables inductive or pad-style charging, as well as short-distance (1.5cm or less) magnetic resonance charging.
The Qi specifications are supported by 193 companies, among them a veritable who's who of electronics, including LG Electronics, Sony, Nokia and Verizon Wireless.
A third leading group behind the push for wireless charging is the Power Matters Alliance (PMA). The PMA's members include prestigious players such as Duracell Powermat, developer of the most widely used wireless charging technology today. Starbucks coffee shops, for example, use Powermat technology to allow patrons to charge properly equipped smartphones and tablets on tabletops.
