American and Israeli researchers have created the fastest wireless network in the world by using twisted, vortex beams to transmit data at 2.5 terabits per second. It is possible that this technique will be used in the next few years to increase the throughput of both wireless and fiber-optic networks. The 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 ...
