Highly innovative, o Li-Fi (Light Fidelity) is a solution that promises speed, security and practicality when accessing the internet. This system standard guarantees web browsing by suspending routers. To connect, the user will only need good LED lighting.
Its difference lies in the transmission of data through the power of light. In this way, innovation predicts speeds 100 times faster than that currently delivered by conventional Wi-Fi.
On theory, any electronic device compatible with Li-Fi will have access to the internet while being below an LED lamp. This way, You can quickly connect anywhere, whether at home or offices.
What is Li-Fi?
Studies believe that light is a resource that could transform connectivity around the world. While Wi-Fi uses radio waves to create wireless connections, the Li-Fi solution relies only on light energy for data transmission.
In an explanatory way, This technology is a communication system that operates through visible light. for it to work, the project uses LED lamps flashing millions of times per second. This modulation of light is so fast that the human eye cannot perceive it..
But, by analyzing the invisible spectrum of light in the infrared, it is possible to read the light pulses as if it were a kind of optical Morse code. Finally, information is quickly synthesized with a readout that converts light into binary data.
Pros and Cons of Li-Fi
In addition to being faster, Li-Fi is an alternative that has less interference and has the ability to reduce the weight of spacecraft. That's because, as discovered by German physicist Harald Hass, the technology is capable of transmitting data bilaterally.
Increased speed remains the biggest benefit: while Wi-Fi has a frequency of 5 GHZ, Li-Fi reaches up to 200.00 GHZ. Internet access security is also another strong point of this innovation.
The risks of unauthorized access are lower with Li-Fi. After all, signal transmission is restricted only to the area illuminated by the light source., not allowing the signal to pass through walls. Nonetheless, despite being innovative, technology also has its cons.
Among them is the fact that the potential of light is limited., which could be harmful especially between companies and industries. Furthermore, not all devices are adapting to this standard and, yet, Li-Fi is not suitable for users who subscribe to slow internet plans.
Market launch
Research into this type of technology has been carried out since the beginning of the year 2000. But, only in 2018 a empresa Oledcomm, from France, obtained rights to effectively exploit Li-Fi.
Europe began testing the new technology in July this year. The first experiment was carried out in space, during the Ariane mission 6. The innovative technology remains in the research phase on the European continent, but also in the United States and other regions of the world.
At the moment, it is believed that Li-Fi could be beneficial for projects such as smart cities, virtual reality and 4K content streaming. Nonetheless, despite the experiments and benefits, The technology must be available within 2 years, compliant or Li-Fi Group.
