A test subject receives ultrasonic hand stimulation, that reportedly causes them to experi...

We've already seen interactive technologies that create smells or tactile sensations on command. Now, however, British scientists have developed a system that they claim can be used to make users experience specific emotions – and it does so without even touching the person.  Read More

The AWIRE keeps two-way radio communications at the ready

Mobile phones are great, but they're not ideal for every communications needs. When you're skiing down a mountain, the last thing you want to do is carve to a stop, dig around your triple-layer winterwear for your phone, and answer just to hear your buddy tell you he's waiting in the lodge – which is where you were skiing down to to meet him. The AWIRE wearable two-way radio promises to deliver that type of conversation in mere seconds so you can get on with your life. It also pairs with your smartphone to route calls and music directly to your ears.  Read More

Persistent Close Air Support (PCAS) enables ground forces and combat aircrews to jointly s...

Since the First World War, airplanes have acted as Close Air Support (CAS) for infantry, though it's been a rocky marriage marked by poor communications and difficult teamwork. DARPA's Persistent Close Air Support (PCAS) project aims to improve coordination between air and ground forces by means of a digital system that works up to seven times faster than regular paper maps and voice radio instructions, and with greater accuracy.  Read More

Drones gather target data about a missile radar station while also jamming it, as part of ...

Modern warfare is a constant arms race of measures and countermeasures, but with development cycles taking decades and costing billions of dollars, it's not uncommon for military technology to become obsolete by the time it's deployed. To address this dilemma, DARPA's System of Systems (SoS) Integration Technology and Experimentation (SoSITE) program aims at replacing monolithic weapon systems with a more flexible cross-platform approach.  Read More

Not all that long ago, to call yourself a broadcaster you needed the blessing of station executives and a pretty smile. But communications technology is advancing so quickly that anybody with an internet connection can now share their perspective with the world. Twitter and Facebook brought this idea into the mainstream with text, photos and emails and now new players are arriving to take things in almost-scary new directions. Launched today, the Periscope live video app can turn anybody with an iPhone into a citizen journalist, whether they be streaming the scene of a disaster-zone or coming at you live from the breakfast table.  Read More

A full-duplex transceiver on an integrated circuit could realize vastly increased data exc...

Full-duplex radio communication usually involves transmitters and receivers operating at different frequencies. Simultaneous transmission and reception on the same frequency is the Holy Grail for researchers, but has proved difficult to achieve. Those that have been built have proven complex and bulky, but to be commercially useful in the ever-shrinking world of communications technology, miniaturization is key. To this end, engineers at Columbia University (CU) claim to have created a world-first, full-duplex radio transceiver, all on one miniature integrated circuit.  Read More

The Pizzicato is a breakthrough in wireless technology – radio frequency transmission usin...

For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a set of patented algorithms without using conventional analog radio circuits in any way whatsoever. This breakthrough technology promises to vastly improve the wireless communications capabilities of everything from 5G mobile technology to the multitude devices aimed at supporting the Internet of Things.  Read More

A new NASA study focusing on irregularities in Earth’s upper atmosphere may help scientists overcome disruptions in GPS communication. The findings provide an insight into the causes of the disruptive regions, and represent the first time that such observations have been made from space.  Read More

In a win for net neutrality advocates, the US FCC voted 3-2 along party lines to reclassif...

The United States Federal Communications Commission (FCC) today voted 3-2 to uphold the principles of network neutrality – that is, to force Internet Service Providers (ISPs) to treat all web traffic as equal. This prevents ISPs from being able to throttle or block users' connections to certain websites, or to offer "Internet fast lanes" whereby large websites could pay for their content to be delivered at a higher speed. Open Internet advocates see this as a huge step to protect the internet's current status as a free and open platform that offers equal opportunities to small and large content providers.  Read More

DARPA’s new initiative, known as the Communicating with Computers (CwC) program, aims to improve the ability of machines to communicate effectively with their human counterparts. The agency has two initial experiments planned, focusing on the somewhat differing fields of improved conversational skills and better cancer detection.  Read More
