Product Background​

Hotspot Details

  • Efficient for a new cryptocurrency, Helium (HNT)
  • Complete set-up in minutes using a smartphone
  • LongFi technology maximizes range and battery life without Wi-Fi, cellular or Bluetooth
  • Low Power – only uses about the same amount as an LED light bulb (5W)
  • Easily manage Hotspots and tokens from the mobile app
  • LongFi™ Technology

longfi

Helium LongFi is a technology architecture that combines leading wireless technology, LoRaWAN, and the Helium Blockchain. LongFi is optimized for miles of range, and long battery life for IoT devices.

proof-of-coverage

RAK Hotspot earns Helium when devices connect, and for validating wireless coverage delivered by peers. Using a system called Proof-of-Coverage, RAK Hotspot earns more Helium when they are in the range of other RAK Hotspot, 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 earns less as they can only issue Challenges over the internet and cannot participate in Proof-of-Coverage.

wireless-coverage

  • Deliver many square miles of coverage from a single RAK Hotspot
  • Based on initial testing, only about 50 to 100 RAK Hotspots are needed to provide complete coverage for an entire city.

connect-anything

  • Create a new global network for billions of devices
  • Any IoT device can become Helium-enabled using readily available off-the-shelf hardware components, software, and a reference design that is open source for anyone to improve upon.
