Engineers have created a transceiver (receiver) for 5G communications, which is completely powered by wireless
The device has two modes of operation:receive mode and transmit mode. In receive mode, the transceiver receives 5G signal and millimeter wave power signal. This signal activates the device and provides it with power. The device then enters transmit mode and sends the 5G signal back in the same direction it originally received it from.

Diffusion of Internet of Things technologiessignificantly increases the number of devices connected to communication networks. Manufacturers of such devices are actively working to provide wireless charging. However, as the authors of the new work note, the key problem of such solutions is the short distances of energy transfer and the need to fix the direction from where you can get the charge.
The developers say that the new device cantransmit energy over a wide range of angles and distances. For example, unlike previous designs, when changing the direction of the wireless power transmission from 0° to 45°, the new device can continue to generate 46% of the power. According to engineers, for analogs, the same value drops to a fraction of a percent.
This is the world's first simultaneous reception of power andcommunication signals with beam control. We sincerely believe that such technologies can revolutionize the Internet of Things and free it from the shackles that bind it today.
