The National Recovery and Resilience Plan (PNRR) is the tool adopted by the Italian government to distribute and invest the European Resources from the Recovery Fund, with more than 220 billion euros of total investments. 27% of the total amount will be invested in digitalization, 40% will be invested to fight climate change and more than 10% will support social cohesion. The plan, divided into six main sections and objectives, includes a series of legal reforms that aim at digitalizing and modernizing Italy, to increasingly attract more and more investments in the long run. This would increase Italy’s GDP and employment rate. Innovation, Culture, Healthcare, and Sustainability are at the core of the digital and green revolution, where technology plays a central role.  

Among several cutting-edge technologies, we have Li-Fi, which characteristics meet the needs of the PNRR, as it offers several benefits in different contexts. Li-Fi is a wireless technology able to transmit data and information through LED light modulation. It is an innovative wireless transmission method:  all the LED light sources become potential data transmitters, and every device is a potential user. Li-Fi has multiple benefits. The first one is speed: this technology can reach up to 100 Gbps in laboratories. Then, Li-Fi is characterized by large bandwidth, about 10’000 times wider than WiFi. Security is also an important feature: being enclosed in a specific area, light is hard to be intercepted by external hackers. Finally, LiFi can be characterized by extreme accuracy when it comes to geolocation: it can offer advanced geolocation and indoor navigation services, as well as the opportunity to transmit proximity content. Differently from other technologies, LiFi does not emit radio waves, therefore it has no interference issues with other devices. This is an electrosmog-free technology that significantly reduces energy consumption in the telecommunication and light engineering sectors by incentivizing the use of cutting-edge LED lamps and using light as a data transmitter.   Considering these beneficial features, LiFi can be applied in several contexts, among which we find healthcare facilities, schools, museums, and transportation, all of which are very important for the green revolution that the PNRR aims at.
