For the first time, technology stepped outside the labs in 2015. When the Etonian company Velmenni installed experimental devices in its office. After setting up, the speed reached 1 GB per second, which is impressive.
Such a technology can gradually replace the existing Wi-fi as two problems are solved at once: lighting and the Internet. Plus, the speed of data transmission is even redundant at the moment. The advantage of Li-fi technology is also that the user can quickly get information, for example, at a public transport stop under a lamp, or cars can update navigation maps or traffic situations simply by being close to such devices. The creation of a seamless network within large agglomerations will also be greatly simplified. (e.g. cities)
The only downside is the way the signal is propagated, which is the light. If there is no source of light, there will be no network. Therefore, the round-the-clock use of such technology in everyday life is still doubtful.
