The relation between the diffusion of smart-working and the Internet infrastructures is debatable and for a better understanding of this association, the research needs to focus more on the local level, a scale where the territorial endowment might act as a barrier in the development of teleworking practices. In Europe, the experience of the COVID 19 closure period and the sudden shift from traditional activities to remote work already created the theoretical frame for a geographical investigation of the ITC endowment, usually at regional scale. Different policy studies (ESPON – T4, e.g.) and some scientific papers (Capello R. and Lenzi C., 2019; Edquist, H., 2022, e.g.) are already focusing on this direction of study. Our approach is based on the integration of large datasets of Internet speed measurements (provided by a specialized company - Ookla) in the local administrative geometry, using the 2021 information and vectors. The integration process allowed us to create local indicators of territorial performance (Internet speed and latency) and to compare them with the business and employees’ structures, in a limited number of case studies – France, Spain, Italy, Poland and Romania. The main conclusion of the European analysis and the case studies points that the combination between ITC infrastructures and smart-working oriented local structures will reshape the map of the economic performance in the EU, raising new challenges for planning and policy design.
