Wi-fi on rays of light: 100 times faster, and never overloaded

and has no comments yet.
Slow wi-fi is a source of irritation that nearly everyone experiences. Wireless devices in the home consume ever more data, and it’s only growing, and congesting the wi-fi network. Researchers at Eindhoven University of Technology have come up with a surprising solution: a wireless network based on harmless infrared rays. The capacity is not only huge (more than 40Gbit/s per ray) but also there is no need to share since every device gets its own ray of light. This was the subject for which TU/e researcher Joanne Oh received her PhD degree with the ‘cum laude’ distinction last week.
