Li-Fi is the technology that can make WiFi disappear

Li-Fi is the technology that aims to replace WiFi, it is nothing new, what happened is that about 10 years ago, it was working in this form of Internet connection, although it is much faster, it has its advantages and disadvantages.

Working on the basis of light, the devices will be much cheaper and at a much faster speed than the current ones. The LiFi system works by transmitting data using visible light. As simple as that, it is necessary to have LEDs, which flash at a speed imperceptible to the human eye, this signal is captured by an image receiver connected to the device that will be used to transmit data (PC, notebook, cell phone, etc.), similar to the system WiFi.

The advantages of this new technology are the stability of the connection, there is almost no interference, the range is very small, and it provides a great deal of safety in traffic. With WiFi, walls are often insurmountable obstacles or weaken the signal, and distance is another inconvenience when we move away from the router. With Li-Fi, the receiver takes the signal with high accuracy in any of the spectra between infrared and ultraviolet, providing low possibilities for signal failure, allowing better bandwidth to be used, without the same suffering from some kind of breakdown.

For home use, it is enough to place the lamps strategically, which will provide a quick and safe service.

Unfortunately, the Li-Fi system is not perfect, if there is no possibility of light from the lamp that sends the signal, then the system does not work. In order to have coverage in a certain area, several lights are needed (eg from room to room), a situation that does not happen with WiFi. Using a cell phone is another problem that needs to be solved, if it is in a pocket or inside a backpack, there will be no access to the light and therefore no access to the network of networks.

Under these circumstances, the million-dollar question isn’t it worth it then? The answer to this question is that at present they are designed for buses, planes and open areas such as hospitals, supermarkets, offices and the like. WiFi download speed is 2.4GHz to 5GHz, with Li-Fi we will be browsing at up to 100Mbps. For now, it will be a matter of waiting to see how this system develops.
