Over five million square kilometers (1.9 million sq mi) of the Australian Outback has no mobile signal, but it does have more than a few Toyota LandCruisers. A plan has now been hatched to take advantage of this fact, which would see vehicles kitted out with Wi-Fi, UHF and other technologies to form a roving network for emergency communications.Read More
The speed of light is a universal constant, but, according to scientists at the University of Ottawa, not that constant. A team of researchers led by assistant professor Ebrahim Karimi has discovered that twisted light traveling through a vacuum moves slower than the speed set by Einstein's theory of relativity, which has implications for quantum computing and communications.Read More
A new system, developed by researchers at MIT, could provide a more streamlined way for robots to communicate with humans in difficult situations, including during emergency response operations. The new model cuts down the necessary communications made by a robot team member by 60 percent, significantly reducing the barrage of data that its human counterpart has to deal with.
Space-based laser communications are moving out of the testing phase and into orbit as the first satellite in the European DAta Relay System (EDRS), or SpaceDataHighway, prepares for launch at the end of January. Likened to having a fiber optic cable in space, the 1.8 Gigabit per second system is a joint public–private partnership between Airbus Defence and Space and ESA that will act as a relay system between ground stations, satellites, and aircraft.
Military airborne communications can be tricky. Not only do they need to overcome attempted disruption from hostiles, but also tackle the difficulties in getting different systems to work together. DARPA is looking to improve things, soliciting proposals to get both manned and unmanned systems communicating faster, more securely and in spite of enemy jamming attempts.Read More
Laser-based communications has the ability to beam enormous amounts of data at high speed, but the use of this technology in space is still in its infancy. To help push things along, ESA’s proposed Asteroid Impact Mission (AIM) will carry out a record-setting demonstration of space laser communications across a distance of 75 million kilometers while orbiting a binary asteroid.Read More
Even with all today's gadgets, it can still be tricky to get in touch with family that's abroad, or even just upstairs. A new device called the Nucleus is aimed at making it quick and simple to speak with family members wherever they are. Surprisingly, it's inspired by the trusty old intercom.Read More
Warships are only as effective as far as they can see, so DARPA's Towed Airborne Lift Of Naval Systems (TALONS) research effort is aiming to extend their horizons by giving them a crow's nest 1,500 ft (457 m) tall by way of a towed parafoil. A TALONS prototype recently completed sea trials off the US East Coast as part of a project to provide ships of every size with better long-distance communications and situational awareness.
A new record distance has been set for the quantum teleportation of information over optical fibers. Researchers working at the National Institute of Standards and Technology (NIST) claim to have transmitted the quantum information carried in light particles over 100 km, four times farther than previously achieved.

BAE Systems is in the process of developing bone conduction technology for use by soldiers on the battlefield. The helmet-based system will leverage the same basic technology as that found in commercial bone amplifying headphones, and should have the effect of allowing soldiers to hear comms over the loudest battlefield noises.Read More
