This presentation was part of our virtual conference (26-29 Apr): WE meet @ Digital Days 2021 Wirepas Mesh is a connectivity protocol for radio modules, optimized for large scale and energy efficient wireless mesh networks. This innovative technology can be used to create large IoT networks, for example using battery-powered sensors, in which each node also functions as a router. In this session, we would like to present the technical characteristics and applications of Wirepas Mesh protocol. Using the Würth Elektronik Thetis-I Evaluation Kit for a live demonstration, we will show how to connect devices in a Wirepas Mesh prototype network in few easy steps.
