This week's Question: A technology called ìLi-Fiî uses light waves from ordinary LED light bulbs to deliver internet connectivity that, according to its creators, is cheaper, more secure, and 100 times faster that broadband internet. Velmini ó a tech company in Tallinn, Estonia ó is the first to test visible light communication technology in a real-world scenario, using Li-Fi-equipped LED lights. According to the International Business Times, the technology transmits data at 1 gigabit per second (Gbps); Li-Fi lab simulations recorded speeds up to 224 Gbps. Li-Fi will not entirely replace Wi-Fi entirely since light waves, unlike radio waves, cannot travel through walls. In addition, the tool does not work outdoors with direct sunlight. The company's co-founder estimates that the technology will be ready for public use within the next two to three years. What do you think? Will Li-Fi catch on?
