Infratel Italia launches a trial of Li-Fi at The National Archaeological Museum of Taranto (Marta)

Over a week ago, the Ministry of Economic Development made the announcement of a successful Li-Fi trial at the National Archaeological Museum of Taranto.  National Archaeological Museum of Taranto (Marta) is the first museum in Italy to use Li-Fi technology that allows fast and secure data transmission through LED light. A national record made possible thanks to the experimentation launched by Infratel Italia in collaboration with the start-up To Be and the Italian Videogames Academy (Aiv).

The “Li-Fi G1” solution developed and tested by Infratel thanks to the geolocation of information and users, allows the delivery of interactive multimedia contents, associated with the individual works on display, on the visitors' smartphones. The Li-Fi signal is decoded by the smartphone camera through a special app created by Infratel Italia and available on the main marketplaces.

In the continuation of the project, the introduction of technologies such as LiFi and AR / VR / Mixed Reality will make it possible to create and deliver puzzles and games, created by taking inspiration from images of works, artifacts or other contents present in the museum or inspired by the city of Taranto; drawings to colour and made taking inspiration from museum photographs, works, maps or images of finds; Static and dynamic storytelling with images and voices dramatized by actors, accompanied and synchronized with images of the museum or specially created.

CEO of Infratel Italia Marco Bellezza said that: “Through the project with the Marta we propose a model that can be applied to many Italian museums and places of culture, promoting a different and more interactive use of our historical and artistic heritage. We are very happy to leave Taranto for this project of national interest”.

The use of Li-Fi technology inside the museum - which currently houses 25 rooms for permanent exhibitions - aims to make the visitor experience as engaging as possible, accompanying the visitor through videos, touch media, images, recordings, Augmented and Virtual Reality, Mixed Reality technologies particularly appreciated by the new generations.

Eva Degl 'Innocenti, Director of the Museum  said: "The project, which sees the Marta as the first Italian museum to use Li-Fi technology, favours the widest accessibility to the cultural heritage, with the aim of making the museum visit as engaging as possible for the visitor. For this purpose, it was decided to introduce new technology to the Marta capable of making the multimedia contents associated with the works on display accessible, making them accessible to all with ad hoc content for the various visitor targets. The aim is to break down all types of barriers, allowing access to visitors with disabilities, such as deaf or blind people ".

What is Li-Fi?

Li-Fi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light-emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a Li-Fi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC):

VLC uses light as a medium to deliver high-speed communication like Wi-Fi and complies with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional, and fully networked wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11.

How does Li-Fi work?

Li-Fi is a high speed, bidirectional, and fully networked wireless communication of data using light. Li-Fi constitutes of several light bulbs that form a wireless network.

When an electrical current goes through to a LED light bulb, a stream of light (photons) emits from the lamp. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can change at extremely high speeds. The signal is sent by modulating the light at different rates. The signal can then be received by a detector which interprets the changes in light intensity (the signal) as data. Also when the LED is ON, you transmit a digital 1, and when it is OFF, you transmit a 0.
