Helium LongFi™ is a technology architecture that combines a leading wireless technology, LoRaWAN, and the Helium Blockchain. LongFi™ is optimized for miles of range, and long battery life for IoT devices.
RAK Hotspot Miners earn HNT when devices connect, and for validating wireless coverage delivered by peers. Using a system called Proof-of-Coverage, RAK Hotspot Miners earn more HNT when they’re in range of other RAK Hotspot Miners, but need to be at least 300 meters apart.
Range depends on the environment, for rural areas up to 10 miles or more, but for more dense areas up to a mile. Single RAK Hotspot Miners earn less as they can only issue Challenges over the internet, and can’t participate in Proof-of-Coverage.
