to implement WifiAt the time, the processes were revolutionary and simplified the use of computers and the connection to other devices, leaving aside the use of cables, at least in practice.
Now the technology is developing levi It is here and can be, more than a replacement, a complement to Wifi; While the second uses “slow” radio frequency waves, the first relies on light.
What is LiFi and how can it be used?
Refers to a light-based wireless communication technology that allows data and location to be transmitted between devices, a term used by Harald Haas, during a talk at TEDGlobal 2011 in Edinburgh, Scotland.
Now, technically, there aren’t many differences with WiFi, but there is a noticeable difference: Wifi uses radio frequency to induce voltage in the antenna for data transmission; while, Li-Fi He carries Adjusting the intensity of the light.
The advantage over Wi-Fi is that it will be implemented in aircraft cabins, hospitals or the military, where it can be used in sensitive areas electromagnetic interference.
Its downside? For LiFi to work, it has to be light bulb on, so its use is limited to the moment of illumination; Any other light sources, such as the suncan interfere with the signal. As if that weren’t enough, the light He can’t walk through wallsso its action spectrum is very short.
But it’s not all bad, Li-Fi stands out as an ideal solution for high-traffic areas, such as shopping malls, where there are many lighting points and a good data transmission network is established.
