Today, the radio spectrum must accommodate an increasing number of IoT devices, and mobile users who require faster data anywhere and anytime. Because of this, radiofrequency connections like WiFi, are becoming oversaturated.
LiFi however, does not use the band of frequencies that currently are used for IoT devices, mobile communications, etc. LiFi transmits data through LED lights that can already be found on the streets, in cars, and in homes.
LiFi can be used to connect us to high-speed wireless internet, avoiding what is known as the spectrum crunch. For this reason, Optiva Media and UC3M are very committed to the research and development of LiFi technology through the MediaLiFi project.
