RAK Hotspot Miner v2 Datasheet

Overview

Description

Hotspot Details

Efficient miner 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

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 Helium when devices connect, and for validating wireless

coverage delivered by peers. Using a system called Proof-of-Coverage, RAK Hotspot

Miners earn more Helium 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.
