XGain is a project aimed at fostering sustainable, balanced, and inclusive development of rural, coastal, and urban areas. The project facilitates access to smart connectivity, last-mile connectivity, and edge computing solutions for stakeholders such as municipalities, policymakers, farmers, and foresters. The main XGain outcome will be the Knowledge Facilitation Tool, a user-centric and easy-to-use online platform that supports decision-making in the selection of internet connectivity and edge technology options with appropriate operational business models. The platform will be validated through a variety of use cases, covering diverse locations, connectivity needs, local requirements, sectors and edge and connectivity solutions. This ensures that we are capable of meeting the wide range of connectivity needs in European rural communities.
