What frequency does LoRaWAN use?

LoRa is the physical layer or modulation technique used for long-range, low-power communications links. LoRaWAN is a communication protocol and network architecture that sits on top of the LoRa physical layer.

The iM881A-M is a compact, low power, bidirectional radio module for the 868 MHz frequency band using Semtech’s LoRa® modulation technology. It has been specifically designed for battery driven devices.

LoRa (Long-Range) is digital wireless data communication IoT technology. LoRa transmits over license-free megahertz radio frequency bands: 169 MHz, 433 MHz (Asia), 868 MHz (Europe) and 915 MHz (North America) .
