Another patent granted to Apple could mean that users of the company’s devices can one day charge them without the use of cables or charging docks — rather, all they would require is a purpose-built Wi-Fi router.
Filed on October 23, 2015 and made public by the US Patent and Trademark Office on Thursday, Apple’s patent application describes a system that harnesses the wireless signals emitted by routers to charge electronic devices.
Theoretically, the router would use dual polarisation and dual frequency antennas to physically locate devices, focus the signal there, and transfer power over a range of frequencies, including cellular (700 MHz to 2700 MHz), Wi-Fi (2.4 GHz to 5 GHz), and millimeter wave (10 GHz to 400 GHz).
