Pasta-shaped radio waves allows infinite channels

Radio waves twisted into the shape of fusilli pasta have been beamed across Venice – and researchers discovered that they allow for a potentially infinite number of channels to be broadcast and received.

The researchers, from the University of Padova, Italy, and the Angstrom Laboratory, Sweden, believe that they have solved the problem of radio congestion.<br /><br />As the world continues to adapt in the digital age, the introduction of new mobile smartphones, wireless internet and digital TVs means the number of radio frequency bands available to broadcast information gets smaller and smaller.

You just have to try sending a text message at midnight on New Year’s Eve to realise how congested the bands are
