Magnetic resonance transmitter delivers power into a magnetic induction receiver

The Qi specification is an 'interface specification'. That means that products on both sides of the interface are free to use whatever technology they like as long as the behavior on the interface is correct.

That freedom is real. 12 different transmitter designs have been approved in the mean time. (Don't confuse "transmitter design" with "transmitter". A "transmitter" is a product that you can use the charge a receiver. A "transmitter design" is a specification.)

Most of these 12 transmitters designs limit the transfer distance to a couple of millimeters. That distance is not a limit of the Qi specification. It is a choice that produces low-cost, highly efficient, transmitters.

The Qi specification allows larger distances. The Wireless Power Consortium has created a Qi transmitter that delivers 5 Watt into a Qi receiver through a 40mm table top. Interestingly, that transmitter uses magnetic resonance operating conditions. This illustrates that magnetic resonance and magnetic induction use the same physics: The magnetic resonance transmitter delivers power into a magnetic induction receiver.

The design of this magnetic resonance transmitter is available for members only. They can find it in the Qi Wiki: http://wiki.wirelesspowerconsortium.com/ (search for CR#123). This transmitter design will be published on the WPC website (as free public download) after the review by the WPC members.

Sony, Toshiba, and LG-Electronics have upgraded their membership of the Wireless Power Consortium. They have joined the highest member category, the so-called 'regular members'.

The wireless power consortium now has 19 regular members out of a total of 106 members:

1. ConvenientPower
2. Delta Energy Systems
3. Energizer
4. Freescale Semiconductor
5. Fulton Innovation
6. Haier
7. Hanrim
8. Huawei
9. Leggett & Platt
10. LG Electronics
11. Nokia
12. Philips
13. Powerkiss
14. Sang Fei
15. Panasonic
16. Sony
17. ST-Ericsson
18. Texas Instruments
19. Toshiba

The regular members jointly govern the wireless power consortium. They make significant investment in time and money to make Qi the global standard.
 

I was in Hiroshima last week and saw this NTT-Docomo shop.

The new NTT smartphones are prominently displayed

With Qi wireless charging pad, of course

And Aquos phone with Qi logo
