What is it?

Li-Fi is a bidirectional, high speed and fully networked wireless communication technology. It uses visible light communication capable of carrying more information, and has been proposed as a solution to the Wi-Fi bandwidth limitations. It can function at brightness levels undetectable to the human eye.

Why is it important?

The exponential increase in mobile data traffic has led to the massive deployment of wireless systems; the University network already hosts over 60,000 devices on any given day. The limited available RF spectrum has been subject to an aggressive spatial reuse and co-channel interference has emerged as a major capacity limiting factor.

What to do next?

To cope with the rapid wireless network requirements, we should continue to investigate these emerging wireless technologies. The University should pilot and prototype a small scale Li-Fi solution while ensuring we maintain the robust infrastructure we already have.
