Communication interoperabillity

  • In the trenchesSeeking 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.

  • Emergency communicationImproving 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.

  • EncryptionFully 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.

  • Emergency communicationDHS 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.

  • Police communicationLouisiana 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

  • CommunicationMaintaining 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

  • Emergency communicationPublic 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

  • Wireless networksIncreasing 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

  • ComunicationiPhones replacing Blackberries at more U.S. agencies

    The security features of Blackberry phones kept them as the favorites with government agencies even as iPhones and Samsung’s Galaxy models were offering more features, but this security advantage appears to have disappeared, and iPhones are replacing Blackberry phones at more and more government agencies

  • Emergency communicationMaryland rolls out public safety interoperable communication system

    To be better prepared for man-made or natural disasters, Maryland leaders have decided to develop Twelve Core Capacities for Homeland Security, picking the deployment of an interoperable communications system as the highest priority; on 5 June 2012, Governor Martin O’Malley inaugurated the state’s new network, known as the Maryland First Responders Interoperable Radio System Team (Maryland FiRST)

  • Emergency communication Home, office WiFi could be used by emergency responders

    Wireless routers for homes and offices could be knitted together to provide a communications system for emergency responders if the mobile phone network fails

  • CommunicationNew algorithm for wireless networks inspired by frog calls

    Males of the Japanese tree frog have learnt not to use their calls at the same time so that the females can distinguish among them and locate the caller; scientists say this is a model that can be used for creating a more efficient wireless communication systems

  • Emergency communicationEF Johnson named to DHS TacCom supplier group

    TacCom is a multiple award Indefinite-Delivery, Indefinite-Quantity (IDIQ) contract established in 2012 to help DHS purchase a full array of tactical communications products, infrastructure, and services for mission critical, public safety communications; the total funds spent on equipment through this contract may not exceed $3 billion, inclusive of options

  • Emergency communicationAlabama on the 9-1-1 forefront -- again

    The first 9-1-1 call in the United States was placed in Alabama more than forty years ago; now, Alabama is on the 9-1-1 cutting edge again by replacing its TDM call routing  with a IP-based and Next Generation 9-1-1 (NG9-1-1) solution; the new system supports voice as well as text, images, video and other IP-based requests for emergency services
