According to a U.S. Patent and Trademarking application that was made public today, Apple appears to be looking for a way to charge devices like the iPhone and iPad using wifi-router signaling. The technique is somewhat similar to the induction charging that it uses for the Apple Watch but increases the distance that the device can be from the charging antenna.
Apple titled the technique “Wireless Charging and Communications Systems With Dual-Frequency Patch Antennas” and appears to have several ideas on how they can get it to work.
