Pasta-shaped radio waves beamed across Venice

March 2, 2012 7:13 am | News | Comments

A group of Italian and Swedish researchers appears to have solved the problem of radio congestion by cleverly twisting radio waves into the shape of fusilli pasta, allowing a potentially infinite number of channels to be broadcast and received. To demonstrate, they did this in real-life conditions by beaming two corkscrewed radio waves across the waters of Venice, Italy.

Radio conference approves bandwidth for ocean current tracking

February 27, 2012 3:10 am | News | Comments

The International Telecommunication Union, which coordinates global radio spectrum use, recently came to an agreement that provides specific radio frequency bands for ocean radars, which until now operated only on an informal basis and were subject to immediate shut-down if they caused interference with other radio systems. The new technology may eventually make real-time detection of tsunamis and oil spills possible.
