The next generation of wireless communications technology will use visible light instead of radio waves, with data piggybacking on interior lighting systems which researchers say will offer both greater speed and better security than today's radio networks. Boston University's College of Engineering (BU) is developing the "smart lighting" system using low-power light emitting diodes (LEDs) that can be switched on and off so rapidly that the change is imperceptible to the human eye.
