In 2012, Qualcomm and Samsung joined forces to start The Alliance for Wireless Power (A4WP), one of many organizations competing to establish a universal standard for wireless charging. A4WP envisions a wire-free future, but chances are you're still packing a series of cables to keep your gadgets juiced up. However, the group just announced a pair of partnerships that could lead to a more unified standard and less corded clutter. WiTricity, one of the major competitors in the wireless-charging space, and the Power Matters Alliance (PMA), a leader in inductive wireless charging, joined forces with A4WP today. While they each have their own wireless charging solutions, the PMA and A4WP have committed to sharing some of their specifications to create a wireless power couple of sorts. McDonalds and Starbucks stores already use the PMA's standard in their charging stations.
In 2011, WiTricity announced a partnership that will see its contact-less, long-field magnetic resonance used to power up Toyotas. With the new partnership, it plans to innovate on and incorporate A4WP's Rezence specifications into its designs. Rezence, A4WP's consumer-facing brand, uses near-field resonant technology to allow users to wirelessly charge several devices with different charging specifications simultaneously. We've yet to see a real-life device sporting Rezence certification, but A4WP showed off a prototype during CES last year, and announced its first certifications last month. WiTricity joined A4WP as a sponsor, which means it gets a seat on its eight-member board of directors, alongside Broadcom, Intel, Qualcomm and Samsung. The group's main competition comes from Qi's Wireless Power Consortium, where Qualcomm also sits on the board.
Wireless charging stations aren't currently very bright, but they're about to learn some new tricks. The Alliance for Wireless Power and the Bluetooth SIG are collaborating on an updated A4WP specification that uses Bluetooth Smart to manage wireless charging sessions. Future Bluetooth-equipped stations should optimize power delivery, prioritize charging for multiple devices and launch apps; you could order a meal by setting your phone down at a restaurant table, for instance. Just when we'll see these smart stations isn't certain, though. When the first A4WP-ready products aren't likely to reach the market until next year, it could be a long time before wireless chargers become truly multi-talented.

The Alliance for Wireless Power (A4WP), a consortium working to establish a new wireless charging standard, hasn't been around for terribly long -- Samsung and Qualcomm joined forces to create the organization just over a year ago -- but it's planning to make waves as quickly as possible. One of the most effective ways to do exactly that, then, would be to persuade large players in the mobile industry to join along, and Intel certainly meets that qualification. The company announced this afternoon that it has officially joined the A4WP's Board of Directors. This move doesn't guarantee that we'll be soon seeing Intel-powered devices with built-in wireless charging capabilities, but it's at least a solid indication that the folks in Santa Clara are mindful of (and intrigued by) the potential that near-field magnetic resonance tech holds.
The Alliance for Wireless Power (A4WP), a group created through the joint efforts of Qualcomm and Samsung, is getting ready to tackle the growing wireless charging market by introducing its very own standard to compete against the likes of the WPC. This morning the consortium, which claims TI, Powermat and Deutsche Telekom (among several others) as members, not only went into greater detail on its plans for the future but also brought along some prototype pads and embedded furniture to show us.
The A4WP's solution is a "non-radiative magnetic resonance-based wireless power transfer ecosystem" -- in short, it allows your phone, tablet or other A4WP-certified gadget (such as light bulbs, as demonstrated above) to charge from a small distance. What does this mean to you, dear consumer? In short, your device doesn't have to be directly touching the pad in order to receive a charge; instead, you could place your phone on top of a notebook or other obstruction (heck, you could even stack your phone on top of another phone or tablet) and still power up your handset. lt will also allow you to place more than one device on the same pad -- and even more than one device type, so tablets and phones can charge together in harmony despite the fact that they both have different power requirements -- and move them around anywhere on the pad without interrupting the charge. These are key differentiators that make A4WP's option a very tempting one for the general user.
It's not quite a "Dear John" letter, but we're sure the Wireless Power Consortium is heartbroken all the same. One of its key members, TI, has just signed up for the Alliance for Wireless Power to build cable-free charging on what's effectively a competing standard. The chip designer doesn't view the move as abandoning a long-time partner, though -- it remains part of the WPC and plans to produce Qi-based wireless power chipsets alongside future A4WP components. Without any related chips to announce, there's a long wait left before we know how well TI can juggle the two charging formats without appearing to play favorites. We'd recommend that the WPC not grow too attached in the meantime.
