Researchers Working on LED-based Alternative to Wi-Fi

Wi-Fi is fast emerging as the most popular technology for wireless communication between disparate gadgets, but security remains a major concern. However, researchers at Boston University’s College of Engineering are working on an alternative way of connecting devices that will be innately more secure than Wi-Fi.

They intend to use LEDs (Light Emitting Diodes) for wireless communications . If they are able to develop an optical communication technology, LEDs could then be used in the same manner as Wi-Fi access points. These LEDs could also be used as a low-power source of light.

Moreover, an LED-based communication technology will enjoy a distinct security advantage. It will be more secure compared to Wi-Fi due to the inability of light to penetrate through opaque surfaces like walls.

“Imagine if your computer, iPhone, TV, radio and thermostat could all communicate with you when you walked in a room just by flipping the wall light switch and without the usual cluster of wires,” said an ebullient Thomas Little, a BU engineering professor, about the idea. Soon, our networks will quite literally “light up”.
