Using light to transmit data is faster and more secure; it's a bright idea.

Most studies have concluded that WiFi is safe, but some people still worry that we shouldn't be bathing in EMF radiation all day and night. WiFi also goes through walls and is not totally secure.

Then there is LiFi, or Light Fidelity, where the invisible flickering of a light source transmits data at very high speed, up to 224 gigabits per second. There are no interference issues as there can be with radio frequencies, and it could be more secure since it can't go through walls.

VLNComm looks to LED technology to provide better network

University Engineering Prof. Maite Brandt-Pearce and her former graduate student, Mohammad Noshad, have found a new alternative to wireless networks like Wi-Fi which uses radio waves. Their new technology “Li-Fi” instead uses LED lights to provide network connectivity.

In wireless networks like Wi-Fi, a wireless adapter converts data into radio signals and transmits it using an antenna. A wireless router then receives and decodes the signal, sending the information to the internet with a physical, wired connection.

Li-Fi Is the New Wi-Fi

This new wireless system hit speeds of 224 gigabits per
second in the lab, and has the potential to revolutionize
internet usage. The Li-Fi technology uses visible light between
400 and 800 terahertz (THz) and transmits messages through
binary code.

- System invented in 2011 hits speeds of 224 gigabits per second in the lab
- Scientists are now testing Li-Fi in offices and industrial environments
- Li-Fi is uses visible light communication and would be more secure

Step aside, Wi-Fi. Scientists have just taken to the streets with a new wireless technology called Li-Fi, and it's 100 times faster than current speeds.

Li-Fi transmits data using visible light communication, and it's now being tested in offices and industrial environments in Tallinn, Estonia.

This new wireless system hit speeds of 224 gigabits per second in the lab, and has the potential to revolutionize internet usage.

Harald Haas from the University of Edinburgh, Scotland invented Li-Fi in 2011.
