The growing prevalence of high-speed wireless communication devices, from 5G mobile phones to sensors for autonomous vehicles, is leading to increasingly crowded airwaves. This makes the ability to block interfering signals that can hamper device performance an even more important — and more challenging — problem.

With these and other emerging applications in mind, MIT researchers demonstrated a new millimeter-wave multiple-input-multiple-output (MIMO) wireless receiver architecture that can handle stronger spatial interference than previous designs. MIMO systems have multiple antennas, enabling them to transmit and receive signals from different directions...

The proposed innovative design leads to unprecedented power conversion efficiency and improved versatility. A recently developed wirelessly powered 5G relay could accelerate the development of smart factories, report scientists from Tokyo Tech. By adopting a lower operating frequency for wireless power transfer, the proposed relay design solves many of the current limitations, including range and efficiency. In turn, this allows for a more versatile and widespread arrangement of sensors and transceivers in industrial settings.

One of the hallmarks of the Information Age is the transformation of industries towards...

NIST and international researchers propose a “cognitive” 6G network—significantly enhancing the 5G network that encodes and transmits data with their meaning or semantics.

With commercial 5G rapidly deploying, researchers have begun to look at 6G. Its key technologies for mobile communication networks are expected to become available as early as 2023, with 6G networks emerging in 2030, according to Saad et al. Compared to 5G, the 6G network will increase data rates by over 100 times, to one terabyte per second or more, enabling the inclusion of edge intelligent devices and computing. To move large amounts of data to where and when it is needed, 6G networks will need to customize services to meet demands, transmit valued data, and interact with users.

New chip eliminates the need for specific decoding hardware, could boost efficiency of gaming systems, 5G networks, IoT, and more. Every piece of data that travels over the internet — from paragraphs in an email to 3D graphics in a virtual reality environment — can be altered by the noise it encounters along the way, such as electromagnetic interference from a microwave or Bluetooth device. The data are coded so that when they arrive at their destination, a decoding algorithm can undo the negative effects of that noise and retrieve the original data...
