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.

Scientists use football fans to test earthquake detection equipment

By - January 19, 2015 4 Pictures
When sports fans get really excited it seems like there's an earthquake – and scientists don't want to let that phenomenon go to waste. As the American football teams the Seahawks and the Green Bay Packers faced off in Seattle on the weekend, University of Washington seismologists with the Pacific Northwest Seismic Network (PNSN) planted seismographs to study the fanmade "earthquake" caused as a way of testing new sensors and software.

Scientists create prototype quantum hard drive

By - January 12, 2015 2 Pictures
Researchers from the Australian National University (ANU) and the University of Otago in New Zealand have created a prototype quantum hard drive that may fundamentally alter the realm of secure, long-distance data encryption. Using atoms of the rare-earth element europium embedded in yttrium orthosilicate (YSO) crystals, the scientists have shattered previous records for quantum information retention by creating a storage device capable of holding quantum state information for up to six hours at a time.
