Two men from the Penn State University seem to have built and tested a device capable of performing wireless transmissions based on reflected infrared light. This device was said to transmit data through the air at a speed six to 14 times faster than the most capable WiFi networks currently in existence. Not only that but the two inventors even state that their system can support data rates “well beyond†the 1 gigabit per second they claim to have reached.
The two inventors are Mohsen Kavehrad, professor of electrical engineering and director of the university's Center for Information and Communications Technology Research, and graduate student Jarir Fadlullah. Part of their setup modulated a beam of infrared light that was focused on the ceiling, with a specially modified photodetector being tasked with picking up the reflections. Such optical networks may prove more suitable and capable in hospitals, factories and aircraft, among others, because, in such cases, radio frequency transmissions can interfere with the control systems, navigation systems or medical devices. - source: softpedia.com
