We live in an ultra-connected world. A new world where a new race is born: The impatient human being. Nowadays, the cellphones have become an extension of our hands and for some years ago –not so many- we cannot live without the Internet neither without Wi-Fi. Lots of people prefer a train for travelling to flight because they don’t need to switch off the electronic devices. The first thing we ask when we are abroad is: may I ask you for the Wi-Fi password please? But as everything in this demanding world, life is moving a step forward and the Wi-Fi has a new competitor: the Li-Fi. Do you know what it is?
Do you remember life before the Internet or how we use to spend our time? Although some memories are still there, we can’t remember the noisy modem trying to connect to the net. We couldn’t speak by phone and surf at the same time either. We did have enough time to go the kitchen and be back and… the computer was still charging the same page! But now, waiting a couple of seconds more for a page to load feels like an eternity. It was exasperating when our friends were late and we couldn’t reach them but we were patient and wait for them 5, 10, 15 minutes or even more. Now, we send a whatsapp or snapchat waiting for a quick response. We are getting more and more impatient.
When the WIFI was invented, it was a huge revolution. Not only because the new impatient human being could surf faster but also cheaper. For those who don’t like wires, like me, this invention was like a blessing. No more wires around!
However, the WI-FI has a new competitor thanks to technology: the LI-FI. LI-FI means light and fidelity and it is an optical wireless communication system. In simple words: the Li-Fi is the optical equivalent of the WiFi and uses the light instead of radio frequency waves.
After the very firsts laboratory tests, it seems to be a promising future for the LiFi and it’s projected to have an annual growth rate around 82% between 2016 and 2018. The LiFi has a lot of advantages: high-speed communication (100 more times than wifi) and being useful in aircrafts, hospitals, etc. without causing electromagnetically interferences. But the most important thing is that in the coming years we will charge Facebook or Instagram in 5 seconds or less.
But there are some disadvantages as well: the light can’t pass through the walls so the implementation of this technology in our homes is, nowadays, improbable. New opportunities? Definitely. The followings years, WiFi and LiFi will live together but I’m pretty sure that in the future digital natives won’t know that LiFi was previously written with W.
