Apple is working on wireless charging
A new patent application from Apple shows that the company is working on a daily basis to wirelessly charge devices via radio frequencies. According to Apple Insider, their new device will be working on cellular and millimeter waves.
Their patent is called “Wireless Charging and Communication Systems with Dual Frequency Antennas”. Patent devices are said to be able to find the physical location of a device with beam antennas and focus on the signal there for a more advanced range and charge rate.
In addition to the general strip antenna on its application, it also talks about power transmission with the 60GHz wavelength used by the WiGig 802.11ad standard. This turns WiGig, a formatted standard, into a logical choice for high frequency. This makes WiGig easier to implement than other millimeter wave solutions.
Their patent document points to potentially valuable solutions. With the Wi-Fi router that will be developed using this technology, it is exciting that phones can be charged independently from the wired and wireless charging stations. However, as with every patent, there is a possibility that a concrete product will not come out in this patent.
