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

LiFi technology and Wifi, have been used to a great extent to be able to carry out various applications and advances, based on their network to the Internet. You may not have heard much about the LiFi, but this technology uses light as the main means of communicating with various data that is sent through it.

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 LiFi, it 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 it can help us in our daily life, 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 by means of 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 the Street 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.

So how are you facilities They 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 is transmitted in such a way that it is modulated by the intensity of light.

In order to function properly, please use LEDs, which are placed at both ends of the transmission and likewise, in the photo detectors that are at the reception ends.

LiFi technology uses light which has a length waveform from 380nm to 780nm, which operates in such a way that there is no interference with the data communication between the LEDs and the photo detectors.

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 a move towards better times, the technology LiFi, does not seek to be a replacement for Wifi. Both technologies can coexist perfectly and work for the comfort of their users, since both have unique characteristics.

LiFi generally operates, at wavelengths that have a range of 380 nm at 780 nm. However, 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, which seeks to develop the LiFi technology it’s 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 speeds of download, of up to 30 Mbps. Likewise, it should be noted that its form of installation and service is one of the most powerful on the market, since it manages to function even while it is 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?
