IEEE Smart Tech Metro Area Workshop: Glasgow

We have held a one day intensive workshop on LiFi.

The workshop will provide the basic technical information about the emerging Li-Fi technology. The differences to traditional radio frequency (RF) based wireless communications technologies will be highlighted. The lectures will cover fundamental digital modulation techniques for Li-Fi as well as techniques to achieve full wireless networking including multiuser access and handover indoors and outdoors using existing lighting infrastructure. In this context, you will see how in the future, novel optical attocell and hybrid networks will enable three orders of magnitude higher area spectral efficiency, and learn how Li-Fi elegantly supports the trend of ever smaller cells in wireless communications to improve data coverage and mobile user experience without the need for expensive new infrastructure. You will also see how using LED lights in a room as a base station or access point, data rates in excess of 10 Gbps can be achieved – this is faster than the fastest Wi-Fi in the 60 GHz band, referred to as WiGig.
