(April 20, 2015) Researchers
at Oregon State University have invented a new technology that can increase the
bandwidth of WiFi systems by 10 times, using LED lights to transmit
information.
The technology could be integrated with existing WiFi
systems to reduce bandwidth problems in crowded locations, such as airport
terminals or coffee shops, and in homes where several people have multiple WiFi
devices.
Experts say that recent advances in LED technology have made
it possible to modulate the LED light more rapidly, opening the possibility of
using light for wireless transmission in a “free space” optical communication
system.
