Twist and shout [News]

A team led by engineers at the University of Southern California has sent multiple channels of data over a single frequency by twisting them together into a beam resembling a piece of fusilli pasta. By combining several polarized beams carrying information into a single spiraled beam, the team was able to send up to 32 gigabits per second across 2.5 meters of open air, a rate around 30 times as fast as an LTE wireless connection.
