Helium LongFi™ is a technology architecture that combines a leading wireless technology, LoRaWAN, and the Helium Blockchain. LongFi™ is optimised for miles of range, and long battery life for IoT devices.
The Nebra HNT Indoor Hotspot Miner comes in three different frequency variants:
- 470 MHz (CN470) – this is suitable for China.
- 868 MHz (EU868, IN865, RU864) – this is suitable for EU, India, Russia and a variety of other countries.
- 915 MHz (US915, AU915, KR920, AS923-1/2/3) – this is suitable for USA, Australia, New Zealand and lots of countries in South America and Asia.
If you are unsure which frequency you need to order you can take a look at our “What Helium Region” tool created by our engineer Ryan.
In the Nebra HNT hotspot miners, the frequency plan for the LoRa concentrator (for example US915 or AU915) is determined automatically based on the location that you choose for the “location assert”. This means that within the frequency variants (470 MHz, 868 MHz, 915 MHz) you can move it to a new location with a different frequency plan and it will auto-update. This only works within a single frequency – for example you can change from a US915 to AU915 location. But you can’t change from a US915 location to EU868 or CN470 without changing the concentrator module.
