DARPA strengthens lines of communication with digital close air support system test

By - April 10, 2015 3 Pictures
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.

DARPA looks at "system of systems" to maintain US air superiority

By - April 1, 2015 4 Pictures
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.

Periscope turns any iPhone user into a live broadcaster

By - March 26, 2015 1 Picture
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.

Full-duplex radio integrated circuit could double radio frequency data capacity

By - March 17, 2015 1 Picture
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

World's first fully digital radio transmitter built purely from microprocessor technology

By - March 5, 2015 1 Picture
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.

Net neutrality win: US FCC reclassifies broadband as a public utility, bans internet "fast lanes"

By - February 26, 2015 1 Picture
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

New electronic technique promises to double optical fiber communications reach

By - February 10, 2015 3 Pictures
A new method of processing signals via fiber optic cables could vastly increase the distance at which error-free data is transmitted via submarine cables without additional signal amplification. As the technique is capable of correcting corrupted or distorted data being transmitted, it may also assist in increasing the capacity of all optical fiber communications. Read More

Tactonics wants to put feeling into text messages

By - February 10, 2015 1 Picture
Hoping to bring back a bit of the personal touch to today's cold, impersonal digital communications, New Jersey-based startup Tactonics thinks the world might just get hooked on Tact messaging. With about the same effort it takes to send an emotionless, poorly spelled text message, you could send your loved ones a more heartfelt, meaningful "sensory message" that is intended to let them get in touch with your feelings.
