Battle for a global wireless charging standard IkeaNo more wires?Swedish furniture maker Ikea International A/S unveiled a new range of furniture that it says can wirelessly charge some mobile devices. The collection includes tables, desks and lamps which have wireless charging pads in them. The wireless charging works through an energy induction transfer. The furniture itself needs to be connected to a power source. The collection will hit the shelves of Ikea shops in Europe and North America on April, 15, followed by a global roll-out. Ikea’s introduction of wireless charging functionality on some of its new furniture heats up the battle for a global wireless charging standard, of which there are currently three, all struggling to become the global leader. Ikea will equip its new range of furniture with Qi-certified wireless chargers from the Wireless Power Consortium and has also joined the organization. The Qi-standard is supported by smartphone makers like Samsung, HTC and Microsoft. The two other standards are the Power Matters Alliance which rolls out wireless charging facilities at Starbucks SBUX, -0.01% cafes in the U.S. and the Alliance for wireless power, A4WP.
