Six new technologies that will enable faster, better internet to the world
By Cat DiStasio The internet is one of the most important inventions of the modern era. However, current estimates say that only 40 percent of people around the globe have access. As internet connectivity becomes ever more important, new technologies are emerging to connect the entire globe with better, faster service. On several continents, research and development projects are underway to provide internet connectivity via high-altitude balloons -- not unlike those used to capture weather data, unmanned solar-powered drones and next-generation wireless routers. Each offers higher speeds and more reliability than current modes, plus the obvious benefit: getting the world online, all at the same time.
Light-based data transmission can replace wires in hospitals
It's not unusual to see patients in hospitals with wires sticking out of their bodies -- it's just something you expect, especially in ICUs. A group of South Korean researchers, however, believe there's a better alternative: lights. The team from Pukyong National University in Busan is suggesting the use of visible light-based communications or LiFi for some machines, according to IEEE. For instance, it could be used to transmit signals from an EEG, so a patient's head doesn't have to be tethered to an obscene number of wires.
