Engineers at the National Institute of Standards and Technology (NIST) have built a low-cost computer system that connects older public safety radios with the latest wireless communications networks, showing how first responders might easily take advantage of broadband technology offering voice, text, instant messages, video and data capabilities.

DARPA’s Squad X program has taught researchers that artificial intelligence offers advantages not related to faster decision-making, and that electronic warfare systems can behave smartly without being equipped with artificial intelligence.  DARPA

Researchers have learned some surprising lessons from the technologies developed under the Defense Department’s Squad X program, which will end this year. For example, artificial intelligence may not help warfighters make faster decisions, but it does provide a planning advantage over adversaries. Furthermore, when it comes to detecting and electronically attacking enemy signals, systems can make smart decisions without artificial intelligence.

Haifa, Israel- based Elbit Systems Ltd. will supply their E-LynXTM Software Defined Radio (SDR) solution for the combat battalion level of the Spanish Army. The new radio network for the battalion level is a first step in the Spanish combat radio network modernization program, the compnay reported. Elbit will provide hundreds of handheld E-LynX SDR systems for dismounted soldiers and vehicles that will be installed onboard a range of combat platforms. Elbit will perform the work in cooperation with the Spanish telecommunications firm Telefonica, S.A. over a period of six-months.
