Testing the system on Wi-Fi networks at MIT, where 2 percent of packets are typically lost, Medard’s group found that a normal bandwidth of one megabit per second was boosted to 16 megabits per second.<\/strong> In a circumstance where losses were 5 percent\u2014common on a fast-moving train\u2014the method boosted bandwidth from 0.5 megabits per second to 13.5 megabits per second. In a situation with zero losses, there was little if any benefit, but loss-free wireless scenarios are rare.<\/p><\/blockquote>\n

The technology transforms the way packets of data are sent. Instead of sending packets, it sends algebraic equations that describe series of packets. So if a packet goes missing, instead of asking the network to resend it, the receiving device can solve for the missing one itself.<\/strong> Since the equations involved are simple and linear, the processing load on a phone, router, or base station is negligible, Medard says.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
