What if we could use existing technologies to provide Internet access to the more than 4 billion people living in places where the infrastructure can't support it? Using off-the-shelf LEDs and solar cells, Harald Haas and his team have pioneered a new technology that transmits data using light, and it may just be the key to bridging the digital divide. Take a look at what the future of the Internet could look like.

Harald Haas: Forget Wi-Fi. Meet the new Li-Fi Internet

Forget Wi-Fi. Meet the new Li-Fi Internet

Li-Fi, using LEDs to transmit data, offers a green alternative to bridge the digital divide with light instead of Wi-Fi.

Solar cells can act as Li-Fi receivers, decoding data from light changes, enabling high-speed, energy-efficient Internet access.

Integrating Li-Fi with solar cells in everyday objects could connect billions to the Internet without increasing energy consumption.
