We were invited by Smart Catalonia to present during three days at SCEWC2019 the new Solar Urban Hub solution generating Light & Data to illuminate the cities. Our proposal to install 10 pilot units of this solution in small and large cities has raised much interest in the municipalities and Catalan institutions but also worldwide. Countries like Holland, France, USA, Qatar, India, Japan, etc. are very interested in starting deploying these infrastructures to generate light and data network in their cities.
