    You probably know that the 5G millimeter wavelength has the fastest download speed on the fifth generation network. Of course, this spectrum also faces some limitations. For example, millimeter-wavelength signals do not have much range and cannot easily penetrate into buildings. But in the not too distant future, you may be able to charge your phone using the same signals! Researchers at the Georgia Tech Institute have developed a concept wireless power grid powered by 5G millimeter-wave frequencies, according to an article published Friday on the website of the popular journal Popular Mechanics.

    To generate energy in this way, a labeled device is needed that can trap the electromagnetic energy from the 5G base stations. Currently, this energy is used only for data transmission. Manos Tentzeris is a professor of electronics at the Georgia Institute of Technology, and the faculty research team led by him has developed a special lens to capture the energy generated by the 5G millimeter-wave signals. This special lens is actually a small rectenna or "rectifier antenna" called the "Rotman lens" that collects the energy sent by the 5G wireless network. But the cool feature of 5G signals that make it a great way to power a power grid is the ability to concentrate energy.

    Jimmy Hester, a graduate of the Georgia Institute of Technology, is the lab's senior consultant on the research team. According to Hester, 5G base stations operate at high frequencies, which allows them to concentrate energy. In other words, we are talking about the conscious energization of the devices themselves, which is done by concentrating the beam towards the device in order to illuminate and supply its energy.

    The key throughout the project is the Ratman lens; Flexible lens that collects energy from different directions. This is the same technology used in military surveillance systems that can detect the target in different directions without having to move the antennas. According to Aline Eid, PhD student and senior researcher at the project, just as the camera lens collects all the light waves from each direction and combines them into a single point to create an image, the Ratman lens has exactly the same mechanism. . Simply put, this lens is like a tarantula, because just as a tarantula has 6 eyes, this system can also see in 6 different directions.

    Researchers claim that the Ratman lens can increase the field of view of a labeled device (energy collector) from 20 degrees "pencil beam" to 120 degrees. This makes it easier to collect millimeter wave energy in the 28 GHz band. According to Elaine Aid, if a label-like device is installed on a UAV, energy can be collected from all 5G base stations in a city.

    Of course, this system has passed its first days, and now, rectenna labels can only collect up to 6 microwatts of energy. This amount of energy will be enough to run small IoT devices up to a radius of 180 meters. It should be noted that in the laboratory environment, the amount of energy collected has reached 21 times what was said.

    Tentzers stated that his team is looking for an investor and financing for the project and is willing to work with wireless operators in this regard. Because in this case, these operators can install tags throughout the cities at the same time as building 5G networks. According to Tenzeris, in the early 2000s, companies moved from voice to data. Now, with this technology, companies can also add energy to communications/data.

    With the development of this technology in the future, it is not unlikely that we will see the installation of rectenna labels inside wearable devices or even sewing labels to clothing. Regarding the financial aspects of the production of these labels, according to Tantrizis, the cost of producing each label is only a few cents, so the technology will not face financial constraints for expansion.

    Tentzers believes that scalability is important in the commercialization of this technology, because we are talking about the production of billions of devices. The prototype of this label may work well in the lab, but in response to those who ask you "Can everyone use it?" We need to be able to say yes, so it is unlikely that in the future, by connecting 5G network, while communicating with others, you can also charge your phone!
