The document discusses a new wireless data transmission technology called Li-Fi that uses LED light bulbs to transmit data instead of radio waves. It notes that current wireless networks are inefficient, unsecure, and oversaturated due to the high volume of data usage. Li-Fi could provide wireless internet access through everyday light fixtures like lamps and replace congested radio wave networks with light wave transmission, but there are still challenges to address around implementation costs and signal interference.

Harald Haas: Wireless data from every light bulb!

2.  Inefficient!
 Unsecure!
 Oversaturated!

3. 1.4 million! 5 billion data phones!
cell towers!
Over 600 terabytes monthly!

4. Replace radio waves with light waves,
using light emitting diodes (LEDs)!
Wireless data through everyday light bulbs!
Li-Fi!
