WiFO System Increases Bandwidth with Light

Apr-22-15 By using LED lights to transmit data, the WiFO system from OSU increases WiFi bandwidth tenfold, and can be integrated into existing systems.

The WiFO system was developed as sort of hybrid system to help existing WiFi systems handle increased demands on bandwidth. Still in the prototype stage, the WiFO (WiFi and Free-space Optic) builds upon the evolution of LED technology that makes it possible to modulate infrared LED light more rapidly in order to transmit data wirelessly. Made of off-the-shelf components, the system transmits the data through an invisible cone of light about three feet square. The system can transmit about 100 megabits per second to each user, rather than dividing the available amount among many different users, via a small, inexpensive diode attached to the user's device.
