Helium Hotspot LoRaWAN Gateway also Earns Cryptocurrency

A Helium Hotspot is a LoRaWAN gateway that also allows you to earn HNT cryptocurrency, and it could more than just prove a way to fund the deployment of public LoRaWAN networks, as as we’ll see below some people or companies are making some serious money, while others not so much. A DIY Helium Hotspot can also be made from a Raspberry Pi 3/4 and a RAK2245 Pi HAT.


Helium Hotspot key features and specifications:

  • SoC – Quad-core Arm Cortex-A53 application processor
  • System Memory – 1GB RAM
  • Storage – 64GB Storage
  • Connectivity
    • Ethernet
    • Dual-band Wi-Fi
    • Bluetooth 4.2 LE
    • LoRaWAN bands – RF: 902-928MHz (US), 868MHz (Europe), 779MHz (China)
    • Capacity: Approximately 1.5 million devices per day, 62,500 per hour
    • ZOE-M8Q GNSS timing module
  • Power Consumption – 5Watts
  • Dimensions – 14 x 14 x 3.8 cm

The specs are a bit better than MatchX M2 Pro, but there’s no ASIC for crypto-mining, and instead, Helium relies on the same low-power Proof-of-Stake model, except it’s called “Proof-of-Coverage challenge”. HNT token allocation is currently 5 million per month, and are shared among users depending on the work done by their gateway(s), as well as to pay for network data transfer and maintain the infrastructure.

There’s no mention of the LoRa module used, but there are instructions to build an Helium Hotspot with a Raspberry Pi 3/4 and RAK2245 Pi HAT, and the source code is on Github. Considering Helium Hotspot is only currently available in some countries, and it costs 450 Euros to purchase, make your own look like an interesting proposition, except I was told DIY gateways cannot participate on the blockchain yet, but that something that should change next month (September 2020).

The price of the gateway is quite steep, so it would be interesting to find out how much money you can actually make… The answer is it depends on the location and traffic going through your gateway. But it’s easy to check as everything is public just like most other blockchain-based solutions.
