LED lights could become network devices, too | CNET News
Fraunhofer Institute has demonstrated how conventional LED lighting could be used to send and receive data to laptops or smartphones, with speeds up to 3Gbps.
Today, you’ve got wireless networks that use radio waves and you’ve got optical networks that use light traveling in tiny glass fibers. Tomorrow, if Fraunhofer Institute research comes to fruition, a combination of the two could turn living-room lights into network devices.
The German applied-research lab has developed wireless networking that uses rapidly blinking LEDs to transmit data through the air. The technology can send data at speeds up to 1 gigabit per second — and by using three colors of light, triple that data rate is possible, Fraunhofer said.
