2016 patent shows that Samsung is working on over the air wireless charging
Samsung's patent, filed in South Korea, describes a method to focus energy on devices in a room that is equipped with OTA wireless charging. The system would allow devices to charge wirelessly even if the user is walking around, thanks to reflectors that would send the charging signal around any obstacles in the enclosed space.
This is obviously a very useful technology which should be available sometime in the next three to five years. While it isn't clear which company will be first to the finish line, the more firms that work on this technology, the faster we will see it ready for real life use.
