Lifi or Light Fidelity is one of the technological innovations generating the most excitement in the field of wireless connectivity.
This new technology promises to revolutionize the way people connect to the Internet and share data.
This is particularly useful in an increasingly connected world with a growing demand for faster and more efficient data transmission technologies.
The expectations surrounding Lifi are such that, depending on its development, it could become a viable and even superior alternative to Wifi.

What is Lifi?
As its name indicates (Light Fidelity), it is a wireless communication technology based on the use of LEDs (light-emitting diodes), using visible light, such as infrared or ultraviolet, to transmit data.
That is to say, it uses light modulation to send information at high speeds, unlike Wifi which uses radio waves.
The technology relies on the ability of LEDs to flash or modulate light at speeds imperceptible to the human eye.
This modulation is then captured by a receiver, such as a photodetector or specialized camera, to convert it into electronic data.
Finally, this data is processed by the receiving device for use, such as a computer or phone.
This process allows Lifi to transmit large amounts of data at speeds much higher than those offered by Wifi.
In this way, it opens the door to new possibilities for wireless connectivity.
Advantages
Lifi offers a series of significant advantages that make it a strong competitor against Wifi. These are:
- Higher transmission speed: Tests suggest that Lifi can reach speeds of 10 GB per second, a figure higher than Wifi.
- Less interference: The use of light minimizes interference from radio signals or other electromagnetic sources, providing more stable and reliable connections.
- Enhanced security: The Lifi signal does not penetrate walls, limiting its range, which reduces the risk of unauthorized access to the network.
- Energy efficiency: LEDs are known for their energy efficiency, resulting in a benefit for the data transmission system.
- Greater bandwidth: Visible light has a greater bandwidth than radio waves, allowing for better handling of more simultaneous data.

Its Future
Although Wifi remains the most widely used option for wireless connectivity, Lifi offers a very promising alternative.
Its ability to offer higher transmission speeds, combined with its capacity to reduce interference and improve security, makes it a key technology in the next generation of wireless communications.
Depending on how it develops, we may see a shift to this new technology, especially in environments where speed and security are of utmost importance.
The era of Lifi is just beginning, but if used well, its impact could be as great as that of Wifi in its time.
