Forget about chargers, soon your future iPhones, iPads or smart watches could charge themselves via Wifi, simply by connecting to a router.
Recently, Apple has been granted a patent for a system which will enable the company’s products to harness the wireless signals emitted by wifi routers, your devices won’t require any cables or charging docks.
The routers will be designed with specialized antennae and circuitry systems which could boost the wireless signal with even more output power, that would then be harnessed by a receiver located in the iPhone.

The routers would be able to 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).
However, this type of wireless charging system is not entirely a new concept. In 2015, the University of Washington had developed a way to broadcast power to remote devices using wifi.
Apple has not yet confirmed that it is working on a router that could facilitate both wifi and power at the same time. Reportedly, the company abandoned its AirPort routers, which used beam steering antennas similar to the patent application, last year.
