In the "Rosetta Rossi" Comprehensive Institute in Rome , in the Primavalle district, it is the first example in Italy , and among the first in the world, to experiment with Li-Fi (Light Fidelity) connection and data transfer technology , a type of connection wireless that uses the modulation of the LED light to connect to the Internet. The project was made possible thanks to the collaboration between Roma Capitale and a startup, To Be.
Rome smart city
"We took this opportunity with great enthusiasm, thus strengthening our commitment to bring Rome towards an increasingly smart, innovative and sustainable future"
Virginia Raggi, Mayor of Rome
These are the words of the mayor of Rome Virginia Raggi, present during the presentation of the project, which join what has already been done in the capital where over 1500 Access points have been activated in over 450 institutes.
“Rome is the first city in Italy, and one of the first in the world, to experiment with Li-Fi in a school. We took this opportunity with great enthusiasm, thus strengthening our commitment to bring Rome towards an increasingly smart, innovative and sustainable future. I am particularly proud that this technology, which is faster, more efficient and more secure than Wi-Fi, is being tested in a Roman school. Our students become protagonists of innovation "
Virginia Raggi, Mayor of Rome
Roma Capitale thus continues on a path of technological evolution aimed at a “smart” urban model based on modern technologies in order to make the city more liveable and accessible.
Connection with Li-Fi technology
This "new" wireless technology uses LED bulbs that emit light to transfer information . The difference between this technology and Wi-Fi transmission technology is the non-use of radio frequencies and all the benefits associated with this.
An example is the possibility of providing a greater bandwidth and at the same time eliminating the potential risks associated with this type of frequency . We also speak of "safe connection" since the connection to the Li-F emitter can only take place inside the cone of light.
Li-Fi is a form of visible light communication that can be traced back to optical wireless communications (OWC) . The name was first coined and used in 2011 by Professor Harald Haas, of the University of Edinburgh, during a speech on Visible Light Communication at TED Global, the annual American conference dedicated to innovation and creativity.
The technology used allows to reach download / upload speeds higher than traditional Wi-Fi , in order to improve the performance of activities by both teachers and students, fundamental in this forced digital turnaround brought about by the COVID-19 pandemic. . The spectrum of visible light is in fact 10,000 times larger than the entire radio spectrum. And in addition to higher bandwidth, Li-Fi can achieve data rates of over 10 Gbps , proving much faster than Wi-Fi.
The Rossetti plant
The system installed inside the computer room consists of nine Li-Fi lamps positioned on the ceiling, they are coupled with LED lamps designed to provide a perfect light / color combination in order to simultaneously allow a psychophysical well-being of the student and Internet broadcast. Technology and light design come together with the aim, in addition to providing an Internet connection, to also encourage students to learn.
“We founded To Be following a dream and a vision: to make every light a source of information. This is the LiFi Revolution. Our startup "
Paolo Russo, Founder of To Be
These are the words of the founder of To Be, Paolo Russo, who spoke of the growth that the company has had in recent months and the desire to expand the staff at their disposal with new talents and further accelerate the growth of their reality.
