Your next smartphone may be able to see through walls

A team of researchers at the University of Texas at Dallas, led by Professor of Electrical Engineering Dr. Kenneth O, have created a technology that could allow future smartphones and cameras to see through walls. The research brought together two scientific advances, one that involves tapping into an unused range in the electromagnetic spectrum and another that deals with a new microchip technology. The terahertz band of the spectrum needed for this technology to function has not been accessible for most consumer devices, however the team is looking to change that. More →

Forget 3G and 4G, terahertz could make cell phones 1,000 times faster

Researchers at the University of Pittsburgh announced that they have discovered a means of wirelessly transmitting data thousands of times faster than current standards, PCMag reported on Wednesday. The team is led by Hrvoje Petek, a physics and chemistry professor at the university, who has theoretically found a way to transmit data between devices in the terahertz frequency. Petek’s discovery of “a physical basis for terahertz bandwidth” could potentially be used to leverage the “portion of the electromagnetic spectrum between infrared and microwave light” and transmit data at rates 1,000 times faster than today’s wireless standards, which are limited to the gigahertz frequency. “The ability to modulate light with such a bandwidth could increase the amount of information carried by more than 1,000 times when compared to the volume carried with today’s technologies,” Petek said. “Needless to say, this has been a long-awaited discovery in the field.” More →
