The NEXT SMARTWAVE project aims to develop and spread solutions to meet the connectivity needs of buildings and smartcities at the level of glazing, namely: Need for connectivity: Bring telephone/cellular connectivity within buildings simply, quickly and energy-efficiently through on-site glazing processing using new laser processes. This will meet the growing demand for in-building connectivity. Security need: Protect user data and health as well as critical equipment with the development of wave-stopping glazing. This need for shielding is particularly demanded in the field of cybersecurity in order to avoid hacking of connected buildings, in the EMC domain in order to protect equipment and ensure its proper functioning and in the field of health by protecting users from the waves.
