DefenceTalkDefenceTalkA DARPA network technology program recently concluded field tests demonstrating novel software that bridges multiple disparate radio networks to enable communication between incompatible tactical radio data links – even in the presence of hostile jamming. The technology is transitioning to Naval Air Systems Command (NAVAIR) and the Marine Corps, which plans to put the software […]https://www.defencetalk.com/darpa-successfully-demonstrates-transitions-advanced-rf-networking-program-76611/

DefenceTalkA quantum sensor could give Soldiers a way to detect communication signals over the entire radio frequency spectrum, from 0 to 100 GHz, said researchers from the Army. Such wide spectral coverage by a single antenna is impossible with a traditional receiver system, and would require multiple systems of individual antennas, amplifiers and other components.

DefenceTalkWith vehicles that are equipped with a new high-bandwidth networking radio, Soldiers can move across the battlefield, rapidly exchanging mission-critical voice messages, images and video with their commanders. Using line-of-sight communications waveforms that are not dependent on satellites, mid-tier networking vehicular radios, or MNVRs, provide ground-level connectivity, which link Soldiers at the company level with […]https://www.defencetalk.com/us-armys-mid-tier-radio-advances-battlefield-network-64345/

DefenceTalkThe U.S. Army has released a request for proposals, or RFPs, to procure additional rifleman radios using full and open competition. The RFP, which was posted Jan. 5 to the Federal Business Opportunities website, moves the Army toward full-rate production, or FRP, for the rifleman radio, part of the Handheld, Manpack and Small-form Fit, known […]https://www.defencetalk.com/army-releases-rfp-for-competitive-radio-marketplace-61807/

DefenceTalkYears before Soldiers used cell phones and social media, and when long-distance calling was expensive, service members would often communicate from remote areas to home via “MARSgrams” or MARS telephone patches. These services were provided free of charge by the volunteer amateur or ham radio operators worldwide who make up the Military Auxiliary Radio System […]https://www.defencetalk.com/armys-military-auxiliary-radio-system-still-relevant-in-internet-age-49966/

DefenceTalkTwo General Dynamics C4 Systems-developed AN/PRC-155 two-channel Manpack radios successfully completed secure voice and data calls from Alaska and the Arctic Circle, using the Mobile User Objective System (MUOS) waveform to connect with the MUOS satellite and ground communications network. The demonstration’s success is a significant operational milestone for the PRC-155 Manpack radio. “Exposed to […]https://www.defencetalk.com/manpack-radios-in-arctic-connect-with-muos-satellites-orbiting-equator-49675/

DefenceTalkRaytheon Company’s jam-resistant, battlefield radio recently transmitted data securely over the air to more than 30 Stryker combat vehicles, proving that it could meet the U.S. Army’s need for a tactical wireless Internet via a vehicle-mounted mobile radio system. The EXF1915, an upgraded version of Enhanced Position Location Reporting System (EPLRS) radios, completed several months […]https://www.defencetalk.com/raytheon-demos-radio-based-network-in-afghanistan-48112/

DefenceTalkMilitary radars, military communications networks, and commercial communications networks all require increasing amounts of limited radio frequency spectrum. Balancing national security requirements of radars and military networks with the growing bandwidth demands of commercial wireless data networks calls for innovative approaches to managing spectrum access.
