Helium is a decentralized wireless network that allows devices to connect to the internet using a unique technology called LongFi. It combines the Helium blockchain with a low-power, wide-area network (LPWAN) tailored for Internet of Things (IoT) devices. Users can set up their own hotspots, which are hardware devices that provide network coverage. In return for sharing their internet connection, these hotspot operators earn Helium tokens (HNT). This incentivizes people to build and maintain the network, enhancing its reach and reliability.The Helium network operates on a proof-of-coverage mechanism, ensuring that hotspots are genuinely providing coverage in their locations. As more hotspots are added, the network expands, making it easier for IoT devices to connect over long distances with minimal power consumption.By democratizing access to a network, Helium aims to create a more robust and cost-effective solution for IoT connectivity, offering a compelling alternative to traditional cellular networks.
