Novel type of Modulation Enabling Multiple Channels on a Given Frequency

This Technique appears to be a Spin - Off derived from optical wavelength applications which is supposed to utilize more degrees of freedom than normal polarisation but otherwise appears to be quite similar and could therefore be used to create multiple channels on a given frequency band. If it works, wireless congestion would quickly become much less of an issue and / or bandwith could be increased dramatically.

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.

heir results have been reported on March 2, in the Institute of Physics and German Physical Society's New Journal of Physics.

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," said lead author Dr Fabrizio Tamburini. The researchers, from the University of Padova, Italy, and the Angstrom Laboratory, Sweden, devised a solution to this by manipulating waves so that they can hold more than one channel of information.

Quite interesting, since the research group seems to have used off the shelf components, maybe a modification as simple as a software update could make at least partial use of the technique?

This could indeed be a game-changer. But they will be taken more seriously if they do not compare their discovery to fusilli pasta.

Already a thread on this one......

(Although not as much detail).

Could be a nice kick in the nuts to providers who are probably planning on raising prices in the near future.
