Ligado, Nokia Announce Partnership on Private 4G/5G

Leonardo Acquires 25% Stake in German Defense Company

Army researchers and industry partners accomplished with a 1-centimeter chip made with hyper-cooled niobium what has always required racks of expensive satellite communications gear in a breakthrough demonstration in Elmsford, N.Y. The U.S. Army Communications-Electronics Research, Development and Engineering Center (CERDEC) and partners HYPRES and L3-Communications demonstrated direct radio frequency digitization in the X-band frequency range using the HYPRES M132 processing chip cooled at 4 Kelvin (-452 degrees Fahrenheit). The breakthrough could in essence take out the "middleman" in military operated X-Band satellite communications frequencies by enabling a signal to be digitized without the need for intermediate frequency "down" converters and other analog components, said Jack Wong, CERDEC's contract officer representative for the project.
