Conclusion

Across the growing ecosystem of Nova Labs–approved Helium miners, one of the most important technical distinctions is the operating frequency band—primarily 915 MHz for the US and 868 MHz for Europe, with certain regions such as India using 865 MHz and China using 470 MHz. While many miners support dual-band operation, several models are built for a single regional frequency, making proper selection essential for compliance and performance.

Despite differences in housing, features, and intended deployment environments, all miners share a common design theme: reliable LoRaWAN connectivity supported by either RP-SMA or N-type antenna interfaces, depending on whether the unit is meant for indoor or outdoor installation. From rugged, enterprise-grade gateways like the Kerlink and LongAP Pro to consumer-friendly indoor units such as Bobcat, Linxdot, and Nebra, each hotspot provides a pathway to participate in Nova’s Helium Network through proof-of-coverage and IoT device support.

Together, these miners offer a wide spectrum of options for hobbyists, integrators, and professional installers, ensuring that users can match the right gateway, enclosure type, and antenna interface to their regional frequency band and deployment scenario.


FAQs

What frequency bands do Nova-approved Helium miners operate in?

Nova Labs–approved miners typically operate in the 915 MHz band for the U.S. and the 868 MHz band for Europe. Some regions use different bands, such as 865 MHz in India and 470 MHz in China.

Can one Helium miner be used in multiple regions?

Many models—such as the Bobcat Miner 300, RAK Hotspot Miner, Linxdot, Syncrobit, and LongAP gateways—support both 915 MHz and 868 MHz, making them suitable for US/EU operation. Others, like the Nebra Indoor/Outdoor and ClodPi Pro, are single-band devices built for one specific region.

What antenna connectors do Helium miners use?

Most indoor miners use RP-SMA connectors, while outdoor or professional gateways (such as Kerlink or LongAP Pro) typically use N-type connectors, which are more rugged for external installations.Most indoor miners use RP-SMA connectors, while outdoor or professional gateways (such as Kerlink or LongAP Pro) typically use N-type connectors, which are more rugged for external installations.

Do Helium miners come with antennas included?

Yes. Nearly all miners include a LoRa antenna:
