Researchers from Czech Technical University in Prague, Czech Republic, Indian Institute of Technology, Delhi, India, and Northumbria University, UK are studying relay-assisted visible light communications to improve the indoor coverage of mobile network connectivity. Their new technique turns mobile phones into relays, forwarding data from the transmitter to the end user.
Researchers from IISST used simple polymethyl methacrylate (PMMA) to partially correct a turbulent laser beam and restore its statistical order.
