Downloading...with light!

The common form of transmitting data today is using WiFi or Bluetooth, which has its limitations. What if there was a way that we could download whole movies in a second. Well it has been done before with something called LiFi. Lifi is wirelessly transmitting data through very fast light pulses, faster than the human eye can see. As it transmits using light, there is very little interferences and very fast transfer speeds (up to 28 Gigabytes per second), compared to tradition WiFi signals through electromagnetic radio waves. LiFi is also very secure as a hacker cannot access the signal unless they have direct visual access to your data, in other words they practically have to be in the same room as you. This is also a downside to LiFi, it cannot pass through solid objects like Wifi can so it will not work in different rooms. Although inexpensive to implement, LiFi will most likely not be commercially available due to its limitations. Light travelling through fibre-cables is in use in infrastructure around the globe to deliver internet at relatively high speeds. It is more than possible that LiFi will be a part of our lives at some point in time.
