LiFi, a wireless technology used to transmit high speed data, was first invented in Scotland by scientist Harald Haas, who demonstrated that by flickering an LED lights at extremely high speeds, one can transmit more data than a cellular tower. Scientists have tested LiFi in their labs and have been able to chieve speeds upto 224 GB/s! Now, for the first time since its inception in 2011, LiFi has been tested outside a lab situation, indicating that the technology may be available for consumer usage sooner that we hoped. Currently, LiFi is being tested in office and industrial work environments in Tallinn, Estonia. Why Estonia? Well, for those of you who don't know, Estonia is one of the world's most tech savvy country.
