The document discusses the history and growth of The Things Network (TTN), an open global network for Internet of Things devices. It was founded in 2015 and has since expanded to over 350 cities in 70 countries with over 800 active gateways. Key aspects of TTN include its open-source and community-driven approach, with users owning the network rather than telecom companies. The goal is to boost IoT innovation by bringing people and technologies together to build the network.
