Computex: A4WP's Rezence wireless charging could be in all tablets and laptops by 2015

Intel is working with OEMs to bring the standard to devices with Broadwell successor

TAIPEI: INTEL AND the Alliance for Wireless Power (A4WP) group are working to bring wireless charging as standard in laptops, tablets and smartphones as early as next year.

Speaking in an Intel Satellite event at the Computex trade show in Taiwan on Wednesday, Intel PC Client Group GM Kirk Skaugen said that the firm is looking to launch the standard in mobile devices in its next-generation Core processor after Broadwell.

If the standard is built into devices with Intel's Broadwell successor Core chip and Intel follows its usual Core chip release pattern of a generation every year, we could well see the integration of wireless charging by 2015. For example, Intel's second-generation Sandy Bridge was announced in 2011, third-generation Ivy Bridge in 2012, fourth-generation Haswell in 2013 and fifth-generation Broadwell in 2014. So assuming the sixth-generation Core family is announced this summer, it should arrive by the end of 2015, following Intel's usual time-to-market pattern.

Demonstrating how the technology will work, Skaugen said, "Intel is working with the A4WP standards organisation in supporting magnetic resonance technology [called] Rezence [...] We are very excited about this as the problem with conductive [wireless charging] today is that you have to direct connect to the pad [and] you have to position your phone or tablet by the millimetres for it to charge."

Skaugen then went on to demonstrate how the technology will work if it is built into tables in Starbucks, which can be seen in the video below. As you will see from the video of the keynote below, Skaugen shows how an ultrabook reference design is automatically powered up and begins charging as soon as it reaches the surface of the table due to the magnetic charge field.

"Sitting on top of a table you might see in Starbucks, or an airline lounge, it generates a charge field. We will basically design these charging products in the form of charge mats which could go onto your desk at home," he added.

After demonstrating how the technology works, Skaugen also announced new additions to the AWP4 consortium to help bring the technology to as many future devices as possible, including Lenovo, Logitech, Asus and Toshiba, which he said are "all uprooting the standard".

The A4WP aims to standardise wireless power transfer and liberate mobile devices from wired chargers, charging multiple devices simultaneously without the need to dock them. It also believes the development of magnetic resonance technology will improve the customer experience when it comes to charging.

Skaugen said that Intel and the A4WP group will also develop phone covers and battery packs that use the wireless charging technology to add the standard to existing devices. µ
