• Marines test latest battlefield IT at Agile Bloodhound ‘13

    Marines in Hawaii last week demonstrated that using handheld devices and special software automatically to sift through loads of data can help ease information overload and deliver made-to-order intelligence to the front lines. “We’re trying to create a user-oriented world view for Marines,” said Col. William Zamagni. “Whether they’re in command centers with PCs, in vehicles with laptops or on foot with smartphones, Marines need access to the most pertinent information possible.”

  • Teams show robust radio techniques at Spectrum Challenge event

    Radios are used for a wide range of tasks, from the most mundane to the most critical of communications, from garage door openers to first responders to military operations. Wireless devices often inadvertently interfere with and disrupt radio communications, and in battlefield environments adversaries may intentionally jam friendly communications. To stimulate the development of radio techniques that can overcome these impediments, the agency launched its Spectrum Challenge — a competitive demonstration of robust radio technologies that seek to communicate reliably in congested and contested electromagnetic environments without direct coordination or spectrum preplanning.

  • Unified military intelligence picture dispels the fog of war

    Military operations depend upon the unimpeded flow of accurate and relevant information to support timely decisions related to battle planning and execution. To address these needs, numerous intelligence systems and technologies have been developed over the past twenty years, but each of these typically provides only a partial picture of the battlefield, and integrating the information has proven to be burdensome and inefficient. DARPA’s Insight program aims to bring real-time, integrated, multi-source intelligence to the battlefield.

  • Justice Department sues to block release of FirstNet-related information

    A federal court in Des Moines, Iowa, accepted arguments by Justice Department lawyers to issue a temporary injunction to block the release by an Iowa Sherriff of e-mails pertaining to a public safety communication network. The Justice Department argued the release of e-mails could seriously impede plans for this single, interoperable network designed to resolve the communications problems that hampered responses to the 9/11 terrorist attacks and other disasters. FirstNet, to whose board Fitzgerald was appointed last year, was authorized by Congress in 2012 to develop and deploy the communications network and is housed in the Department of Commerce.

  • Secure, private Internet and cloud to soldiers, marines at the tactical edge

    Squads of soldiers or marines on patrol in remote forward locations often do not have the luxury of quickly sharing current intelligence information and imagery on their mobile devices, because they cannot access a central server. Troops frequently have to wait until they are back at camp to download the latest updates. In the meantime, mission opportunities may erode because the information needed at the tactical edge isn’t immediately available. DARPA’s Content-Based Mobile Edge Networking (CBMEN) program aims to provide an alternative approach to the top down focus of most military networks by starting the content sharing at the individual soldier or marine level.

  • Guaranteeing communication coverage in the event of disaster

    An EU-funded project that aims to develop a rapidly deployable wireless communication network for use in the aftermath of an emergency, disaster, or unexpected event, was commended recently at an international event.

  • Competitors selected for DARPA Spectrum Challenge

    As wireless devices proliferate and the radio spectrum becomes ever more congested, all users have a common interest in radio technologies that can accommodate the largest number of users but still enable priority traffic to get through. Three wild card selections remain to be selected for the DARPA Spectrum Challenge, a competition aiming to demonstrate solutions for more robust wireless radio technologies.

  • Seeking new ideas for mobile ad hoc networks (MANETs)

    Troops operating in forward locations without telecommunication infrastructure often rely on a mobile ad hoc network (MANET) to communicate and share data. A constraint with current MANETs is they can only scale to around fifty nodes before network services become ineffective. DARPA is exploring new technologies unencumbered by Internet Protocols (IP) which could be the key to enabling large MANETs. The Internet facilitated far-reaching technical advances, but in this technology area the Internet may be the roadblock.

  • Improving emergency radio communication

    Radio communications can be unreliable in underground tunnels and other large, complicated structures, posing a safety hazard for emergency responders. New tests of wireless emergency safety equipment by the National Institute of Standards and Technology (NIST) have defined the challenges more precisely and suggest how emergency communications might be improved.

  • Fully secure communication

    Can worldwide communication ever be fully secure? Quantum physicists believe they can provide secret keys using quantum cryptography via satellite. These physicists have, for the first time, successfully transmitted a secure quantum code through the atmosphere from an aircraft to a ground station.

  • DHS helps tear down technological “Tower of Babel” along U.S. borders

    First responders and international officials on both sides of the U.S.-Canadian border had been preparing since last fall for the Canada-U.S. Enhance Resiliency Experiment (CAUSE) — demonstrating the ability to exchange information between local, state, provincial, and national systems and software applications. With these preparations, a recent joint experiment held in Maine and New Brunswick proved that even across borders, any immediate confusion or lack of information following an incident should not greatly affect overall rescue efforts.

  • Louisiana parishes to encrypt police radio communication

    First-responder agencies in Orleans, Jefferson, St. Bernard, and Plaquemines parishes in Louisiana will soon be encrypting all emergency radios,  keeping emergency response chatter out of the ears of the public; the police says the   encrypted communication is needed  in order to keep criminals from gaining information on police by listening to scanners, but a police union and crime-prevention groups are worried that the encrypted system would prevent the media from monitoring police activity, and hobble neighborhood watch organizations from keeping their neighborhoods safe

  • Maintaining robust communications in congested and contested environments

    Radios are used for a wide range of tasks, from the most mundane to the most critical of communications, from garage door openers to military operations’ as the use of wireless technology proliferates, radios and communication devices often compete with, interfere with, and disrupt the operations of other devices; a new DARPA challenge is looking for innovative approaches that ensure robust communications in such congested and contested environments

  • Public safety networks coped better with Sandy than commercial networks

    A new nationwide Long Term Evolution (LTE) network for first responders will be built under the supervision of the First Responder Authority (FirstNet); this network will be an improvement over the commercial networks that experienced outages during Hurricane Sandy

  • Increasing the efficiency of wireless networks

    A “spectrum crunch” is quickly being accelerated as customers convert from traditional cell phones to smartphones and tablets; new method, which doubles the efficiency of wireless networks, was developed by researchers; it could have broad impacts on the mobile Internet and wireless industries
