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.
“In addition to improving the experience for users, the two big advantages of this system are that it uses inexpensive components, and it integrates with existing WiFi systems,” said Thinh Nguyen, an OSU associate professor of electrical and computer engineering. Nguyen worked with Alan Wang, an assistant professor of electrical and computer engineering, to build the first prototype.
The electromagnetic spectrum with wifi can be flakey and interconnecting access points using this spectrum can fail frequently and cause significant bandwidth problems. Integrating led tech into devices may take time to develop some kind of standard but using this for point to point wireless communication could prove very useful in certain use cases.
