Response to IHS iSuppli recent report – Hurdle to wireless power adoption lack of common standard

Fully agree on the need for a standard similar to Wifi or Bluetooth to help accelerate adoption of the wireless power technology. The Wireless Power Consortium (WPC) was established by a group of companies in 2008 for the very purpose of establishing an international standard for interoperable wireless charging. The technology is based on inductive power transfer. The consortium currently has 80+ members including the likes of Nokia, Samsung, LG, Motorola, Philips, Verizon wireless, Orange Telecom, Energizer, Texas Instruments, STE, Atmel etc.  See full member list @   

The WPC released its Version 1.0 of the spec in Fall 2010 with a logo as "Qi" (pronounced Chee, meaning vital energy). Any charger carrying the Qi logo (easy to indentify) will charge any device carrying the same logo. The first Qi complaint product was released by Energizer ( Texas Instruments released its first generation wireless power evaluation kit at CES 2011, which allows engineers and designers to easily integrate wireless power technology to existing or new low-power designs. The kit includes a transmitter and a receiver, along with a complete reference design enabling system designer to efficiently implement wireless power into their products. In April 2011, TI released the second generation of wireless power technology with the industry's first and smallest fully integrated receiver. (

As far as current adoption is concerned, just the growth in the WPC membership indicates market acceptance and adoption, along with a wave of recent product releases that are Qi compliant. Battery back covers for Verizon phones have been demoed at various media events. LG has released a charger pad for Verizon while HTC and Samsung have released LTE phones with optional back covers that are complaint to the Qi standard.

As indicated by a WPC release on July 13, 2010, the low-power specification gave the group a starting point for which they can extend the Qi standard to medium power applications (up to 120W). With this in mind, the scope and reach of wireless power technology has only just begun.
