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.
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.
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.
