Flexible wireless power specification rolled out

October 31, 2012 // By Jean-Pierre Joosting
Alliance for Wireless Power (A4WP) has announced that the technical working committee has approved a more flexible wireless power specification that will allow consumers to charge their mobile devices on a variety of compatible surfaces.

"The Alliance for Wireless Power and its members have been focused on creating a more flexible wireless power specification that sets the stage for formal standardization in the future," said Dr. Kamil A. Grajski, president of the A4WP. "Approval of the A4WP wireless power specification establishes a true path forward for the commercialization of wireless charging that will satisfy the needs of most consumers. A4WP and its members will now set their sights on building compliant wireless applications that can be integrated by key industries including automotive, furniture and retail."

The A4WP specification is based on a concept of spatial freedom, which extends wireless power applications beyond the accessory or add-on market to fully integrated solutions in the device as well as surfaces such as furniture and automobiles. The A4WP specification brings a number of unique benefits to the wireless charging ecosystem.

  1. For consumers, the A4WP specification supports simultaneous charging of multiple devices with various power requirements such as handsets, Bluetooth headsets, MP3 players, GPS devices and mobile tablets
  2. For industrial designers, the A4WP specification leverages a loosely coupled magnetic resonance technology and provides more flexibility for charging applications to be installed into automobiles, furniture and other surfaces
  3. For the consumer electronics industry, the A4WP specification takes advantage of broadly adopted wireless technologies, such as Bluetooth 4.0, which will allow manufacturers to minimize hardware requirements
