What is LiFi and what are the differences of WiFi? – Advantages and disadvantages

Contrary to WiFi, which uses electromagnetic waves, with the sole purpose of communicating and taking data to a specific device through the configuration of this wireless network , which can be done thanks to the use of a router and a modem . The LiF i, is understood as an optical communication technology and on its side the WiFi, a technology which carries its communication through radio.

Although both technologies are very similar, the Wifi has certain functions and advantages that the Lifi does not have and vice versa. If you are curious to know about these tools and how they can help us in our daily lives, just keep reading this post and you will find relevant information.

What is LiFi technology?

The main idea of ​​LiFi technology is quite simple. The objective of it is to offer hundreds of users the possibility of connecting to the broadband connection through different light waves.

The deployment of networks, which this type of technology uses, is by means of different types of streetlights, which we can find in places as common as public lighting. They are located in these places, due to the fact of being strategic places, in which the modems are located and they begin to transmit the signal from one place to another.

Just as these installations are made in public places, it is also possible to do it in domestic places, performing the same installation in some domestic light sources.

Knowing more about LiFi technology

LiFi, stands for Light Fidelity, forms a technology which works in such a way that you can have a connection in multiple places in your home or on the street at the same time. Your data are transmitted in such a way that they are modulated by the intensity of light.

In order to function correctly, it uses LEDs, which are placed at both ends of the transmission and likewise, in the photo detectors that are at the reception ends.

The Lifi technology uses light which has a length of wavelength 380 nm to 780 nm, which operates such that there is no interference with the communication of data between the LED and photodetectors.

It can support three different modes, which are: peer to peer, star and broadcast.

LiFi vs WiFi

As the main thing at this time, is to initiate an advance towards better times, LiFi technology does not seek to be the replacement of WiFi. Both technologies can coexist perfectly and work for the comfort of their users, since both have unique characteristics.

LiFi generally operates at wavelengths ranging from 380nm to 780nm. However, the WiFi works in different frequency bands 2.4 GHz and 5 GHz.

How is this technology best used and exploited?

One of the main companies looking to develop LiFi technology is Philips Lightnify. Its creators seek to adapt this tool to all possible areas, regardless of whether you are at home or in your office, you will always be safe and connected.

Each LiFi technology modem allows its users to reach download speeds of up to 30 Mbps. Likewise, it should be noted that its installation and service is one of the most powerful on the market, since it achieves work even while installed in a light source.

What do you think of these types of connections? Now that you know more about it, do you want to change?
