Using "twisted vortex beams," American and Israeli scientists have boosted wireless transmission speeds to 2.5 terabits per second.
As explained in ExtremeTech, the researchers "use orbital angular momentum (OAM) to cram much more data into s single stream." Current technology uses SAM (Spin Angular Momentum). These results came only a few months after Bo Thide at the Swedish Institute of Space Physics proved OAM is possible, and sent a signal over 442 meters (1450 feet).
The 2.5 terabits per second test twisted eight 300Gbps light streams around each other, but only transmitted them for one meter (three feet). Alan Willner and others at USC, NASA's Jet Propulsion Laboratory, and Tel Aviv University believe successful implementation could boost wireless throughput by 1,000 times or more.
It will bring costs down. 1000 times more bandwidth without the bidding wars for spectrum.
