Spotted first by AppleInsider, the patent filed by Apple is named - "Wireless Charging and Communications Systems With Dual-Frequency Patch Antennas".
Wireless charging on smartphones has an ambiguous meaning on paper. Yes!, it is a wireless charging but you still need to keep your handset on the wireless charger which kind of steals that freedom of using your smartphone while it is charging. Although it is not recommended to use phones while they are connected to the socket, Apple’s latest patent reveals that we might get to charge smartphones wirelessly in the literal sense.
Spotted first by AppleInsider, the patent filed by Apple is named - "Wireless Charging and Communications Systems With Dual-Frequency Patch Antennas". Explaining the working, the filing reveals that Apple will use the technology used to transmit Cellular and Wi-Fi signals. However, this time instead of this cellular (700MHz-2700MHz) and Wi-Fi signals (2.4 GHz-60GHz) will transfer electric power to juice up your smartphone.
An antenna receiver will be stick to the backside of your smartphone, which will receive and convert the rays into relevant electric power used to charge our smartphones. Further, Apple is accepted to adopt the technology from Apple’s AirPort routers to detect the receiver and direct all the emissions there.
However, the patent also included a bunch of new technology names including that of dual mode circuitry, dual - frequency patch, dual-polarization etc. which will be disclosed once this new wireless charging innovation closes to reality. As of now, it is only a patent so chances of it implemented in a product much bleaker than you think. Further, including this innovation in the upcoming iPhone 8 looks way more ambitious, as of now.
Even if Apple gets this working, the power transmitted through this technology will be much lesser than what we can usually get through the current wired and wireless chargers. Obviously, the day when we would charge our smartphones wirelessly across the rooms is not far away, but we would advise you to just hold on for a while until it taps more of the practicality aspect.
