Researchers from the Tokyo Institute of Technology in Japan have successfully developed hardware capable of transmitting data 20 times faster than current Wi-Fi speeds using a portion of the electromagnetic spectrum between 300 GHz and 3 THz known as the “T-ray” band. Using a resonant tunneling diode, researchers were able to generate signals at frequencies up to 542 GHz by … [Read more...]

Researchers from the University of Oslo (UiO), Norway have developed instruments for inclusion on satellites that will be launched to investigate why the solar winds that produce the northern lights interfere with radio communications, GPS navigation and satellite transmissions. Universities around the world will cooperate to launch 50 satellites in 2013 to examine all layers … [Read more...]

Tawkon’s app, which measures radiation emitted from handsets during phone calls, was rejected from Apple’s App Store last year. The company has now come out with a redesigned app built specifically for Google’s Android operating system.‪ When Tawkon was trying to go the iOS route, the app put statistics, graphs and a big, circular gauge of radiation front and center. The app … [Read more...]

Wireless companies say that smartphones are threatening to overwhelm their networks, and are asking the government for help. But some experts maintain technology already has the answers. AT&T, Verizon, T-Mobile and Sprint say they need more radio spectrum, the government-rationed slices of radio waves that carry phone calls and wireless data. Martin Cooper, the inventor … [Read more...]
