What if a wireless Internet system could run on nothing more than an LED lightbulb? A new way to transmit data is coming that could radically change the way that devices communicate with each other, Li-Fi. Short for Light Fidelity, Li-Fi uses visible light to send data, creating the link between router and device with imperceptible pulses of light. This type of Visible Light Communication (VLC) uses something that is probably present in nearly every room — an LED lightbulb. Li-Fi can achieve data transmission at 1 GB per second — that’s 100 times faster than current average Wi-Fi speeds. This class introduces participants to this exciting new technology.
