The Night Flight Demonstrator is part of a City of Tomorrow approach. The aim is to integrate state-of-the-art telecommunications network technologies, such as fibre optics, ultra-high-speed radio, 4G LTE and the LP/WAN network, in order to meet the needs expressed by the project partners, to ensure significant digital attractiveness. This Demonstrator will allow to integrate the technologies on which the uses of the future will be based. The aim is to provide a network support capable of integrating the innovations of tomorrow in the long term. The duration of the experiment will be reduced to a full year of experimentation, considering the time of installation and the exploitation of the results.
