This wireless system is almost 8,000 times faster than your fastest wired home Internet connection that can only manage up to 300Mbps

How powerful is your wireless system? Can it smoothly transfer 4 movies at the same time or can it simultaneously stream loaded music files? Sounds crazy? Well, there is a Wi-Fi that can seamlessly do all of that and much more. A set of Israeli and American scientists have been working on a new way to transmit data wirelessly. The good news is that they can now transfer a scorching 2.5 terabits of information per second.
This wireless system is almost 8,000 times faster than your fastest wired home Internet connection that can only manage up to 300Mbps. Literally, the output is the same as transmitting seven full Blu-ray movies per second.
This works on the principle of electromagnetic waves that usually carry data are twisted into vortex beams. Extreme Tech describes the process as: These twisted signals use orbital angular momentum (OAM) to cram much more data into a single stream. In current state-of-the-art transmission protocols (WiFi, LTE, COFDM), we only modulate the spin angular momentum (SAM) of radio waves, not the OAM. If you picture the Earth, SAM is our planet spinning on its axis, while OAM is our movement around the Sun. Basically, the breakthrough here is that researchers have created a wireless network protocol that uses both OAM and SAM.
The combination of the two provides some amazing possibilities. So far, the researchers, from University of Southern California, NASA's Jet Propulsion Laboratory, and Tel Aviv University, have twisted together eight data streams, each operating at 300 Gbps, to achieve the new record of 2.5 terabits per second. At the moment, they've only transmitted signals as far as 1 meter. That should be scaled up before long—though the researchers admit 1 kilometer is probably an upper limit, Gizmodo reports.
