Scientists Twist Radio Beams To Send Data At 32 Gigabits Per Second

concertina226 writes Scientists from three international universities have succeeded in twisting radio beams in order to transfer data at the speed of 32 gigabits per second, which is 30 times faster than 4G LTE wireless technology in use today. The researchers, led by Alan Willner, an electrical engineering professor with the University of Southern California Viterbi School of Engineering, successfully demonstrated data transmission rates of 32 gigabits per second across 2.5m of free space in a basement laboratory.

It's been shown that all these "helical" polarization schemes are degenerate forms of MIMO essentially, and can't achieve speeds better then what MIMO antenna configurations can.
At short distances in quiet environments, you can do a heck of a lot which will never, ever work anywhere but in that experiment.
