LiFi, probamos la tecnología que quiere desbancar al WiFi usando la luz para transmitir datos
AppleInsider has confirmed what one developer has posted on Twitter: traces of iOS mentioning support for Li-Fi networks found in fragments of the system library cache. It has been present since iOS 9.1, so it must have been studied in Cupertino for some time.
We have already talked about Li-Fi networks in Xataka, but they can be summarized as a wireless network to connect to the Internet like Wi-Fi, but they work by means of interruptions of a light bulb that are detected by a receiver diode. With millions of detectable interruptions every second, the theoretical speeds that can be achieved with these networks are 224 Gigabits per second .
The advantage we would have is that we could transmit data from a simple LED bulb , and wherever the light arrives, data can be received. Suddenly, we would have at home a whole network of “routers” ready to send data at speeds hundreds of times higher than we are used to today.
Li-Fi is in an experimental phase, but already promises
For indoors, it seems ideal. For outdoors, it’s already more complicated, because the sunlight would make data transmission very difficult. But outdoors we already have the mobile networks, right?
On an iPhone or iPad, the receiving diode that detects light variations could be in the phone’s own external case (perhaps in the bitten apple logo?), or sticking out at one end of the phone. It is all about seeing how the technology evolves, because at the moment it is in an experimental but promising phase .
