LR1121
The LR1121 is Semtech’s third generation ultra-low power LoRa® transceiver. It provides multi-band LoRa and Long Range - Frequency Hopping Spread Spectrum (LR-FHSS) communication over sub-GHz and 2.4GHz ISM bands as well as satellite S-Band connectivity. The LR1121 is designed to comply with the physical layer requirements of the LoRaWAN® specification released by the LoRa Alliance®, while remaining configurable to meet different application requirements and proprietary protocols.
