Helium Hotspots & IoT Devices | LoRaWAN Antennas, Mounts & FCC Guidelines

Reference Helium hotspots, LoRaWAN IoT devices, 900 MHz antennas, mounting options, and FCC Part 15 guidelines for compliant Helium Long-Fi deployments

Helium hotspot and IoT devices

Helium hotspots and IoT devices power a decentralized wireless network that enables long-range connectivity for LoRaWAN-enabled IoT devices.

If you’re familiar with HNT and Helium mining, you likely want to maximize the performance of your radio-based hotspot.

  • Network Type: LoRaWAN / Long-Fi
  • Primary Band: 900 MHz ISM
  • Use Case: Public IoT coverage & HNT mining

main content

For those new to the ecosystem, HNT is the cryptocurrency of the Helium blockchain a distributed network of hotspots that provides public long-range wireless coverage for IoT devices, with private CBRS networks also under development.

Helium hotspots enable long-range, low-power IoT connectivity by operating in the 900 MHz ISM band. Coverage, antenna gain, mounting height, and FCC compliance directly impact network performance and mining effectiveness.
