Backward compatibility?

Just wondering whether this wireless charging technology will be back ward compatible to the current smart phones, tablets and so on . Or will they require some kind of wireless adapters to be fitted into their charging sockets?

That's a good question. Qualcomm's comments supplied to EE Times' Peter Clarke suggests that Qualcomm is thinking bigger so that it can help the industry with a standard. And yet, it doesn't look like Qualcomm is totally giving up with its own allinace for A4WP...sort of a mixed msg...?

I think Qualcomm wants to bring both technologies on same bench and see how they can merge the idea's. Probably they dont feel any one approach is clear winner so they want to keep both and hance mixed messaging..

My understanding, from recent discussions with Dialog Semiconductor CEO Jalal Bagherli, is that receive side design for wireless charging is pretty simple.

This is a reason Dialog has not pursued that market to date -- complex ICs not really required.

However the send side that will drive the charging mat is more complex.

I think it may be the case that a number of phones start getting fitted with Qi and A4WP receive technology without us even knowing....the issue is when will the interoperability, certification and branding come?

@peter, you wrote:

That is exactly my concern, too. As p_g suspects, Qualcomm "wants to bring both technologies on same bench and see how they can merge the idea's," that may be the case. But that still doesn't get us any closer to the actual adoption of either wireless charging format.
