HI all,

This may well be the next tech for WLAN. See link.

Take care,

Scientists Use LEDs to Create 800 Mbit/s Optical WLAN

Flickering LEDs used for data transfer.

Credit: HomedesigninteriorThanks to the work of researchers at Fraunhofer Institute for Telecommunications in Berlin, Germany, we could be one step closer to a reliable and efficient optical WLAN based off of conventional LEDs. The idea behind such tech is to orchestrate the transmission of data through the rapid flickering of LEDs. Although this isn't the first instance of flickering LED lights used for line-of-sight networking, Fraunhofer researchers have developed a better, faster implementation that is more practical for real life applications.
