LiFi joins the informative “STEM” program Rai Culture. With the science communicator Davide Coero Borga, we had the opportunity to tell the story and evolution of this wireless technology, which uses LED light modulation to transmit data.
Progetto Scienza – STEM is Rai Culture’s informative science program. In Progetto Scienza, Davide Coera Borga meets several innovation and research experts at a global level. This program aims at showing people how science and technology can improve our lives and how they can be a good investment for the future of the youth.
STEM (Science, Technology, Engineering, and Mathematics) is everywhere, even where we don’t think there is. The episodes of this program want to show countless STEM fields of applications.
In the third episode, the focus is all on light and its potential. Among the solutions that the program talks about, we find our innovative technology: Li-Fi, which stands for Light Fidelity.
“Light is very important to us. Not only does it illuminate our space, but it also makes it alive.”- With these words, our CEO Francesco Paolo Russo embarked on a journey with Davide Coero Borga, in which light and innovation were the protagonists.
Li-Fi is a wireless technology that uses light modulation to transmit information. It is an innovative method of wireless data transmission that works through the signal emitted by every LED source: a 0/1 sequence non-detectable by the human eye that allows data transmission. Li-Fi falls within “5G connections” and is a fast, secure, and radio-wave-free technology. Li-Fi is emblematic of light making space alive. All the LED sources are potential data transmitters, and every device is a potential user.
Li-Fi can have several fields of application. For example, with computers, Li-Fi can allow a bidirectional connection to the network, with the name of LiFi S (streaming). Computers, equipped with a USB key, are able to detect and elaborate the signal emitted by the illuminating body, and, in turn, can upload data to the modem, which is actually the illuminating body itself. This light source is equipped with a photosensor that can detect Li-Fi signals.
The beauty of this technology is that it can be applied to so many different sectors: from retail to marketing of proximity to cultural heritage, continuing with healthcare, cybersecurity, smart city, energy & utilities, and so on.
To watch the episode on RAI Play, you’ll find Li-Fi at the minute 30: https://bit.ly/3wzGPRM
