The method in which a wireless charging is used to charge products that require small batteries and low power like the watches, medical implants, hearing aids, cell phones and wireless keyboards is called Radio charging. This technology uses Radio waves for the transmission and reception of television, cellular telephone, radio and Wi-Fi signals. The working of Radio charging is similar to the working of the electrical transmission. In this technology a radio wave gets transmitted and then propagates in all directions till the time it reaches an antenna which is tuned for appropriate frequency to receive it. This technology of Radio charging is used only for small sized equipments or items.
