Download speed of 70 DVDs per second (26th June, 2012)

Internet download speeds are getting faster and faster. A decade ago, we measured things in kilobytes per second; today it's megabytes, and soon it may be terabytes (one terabyte is 1,000 gigabytes). Scientists in the USA and Israel have created a wireless system that can transfer 2.5 terabits per second. That's around 300 gigabytes, or the data on 70 DVDs. If you don't understand those numbers, 2.5 terabits a second is around 24,000 times faster than today's high-speed connections.

Researchers created what they call "infinite-capacity wireless vortex beams" that can transfer an unlimited amount of data. It is the fastest wireless network ever created and it could seriously change how we work and play online. The system works by twisting light in a corkscrew shape and the information travels along the beam of light. Things are still at the early stages – scientists can only send data a distance of one metre. They say that the next step is to figure out how to create satellite-to-satellite communication.
