Semtech LR1120
NEW
The LR1120 is an ultra-low power device targeting global geolocation applications. It provides multi band LoRa® and Long Range - Frequency Hopping Spread Spectrum (LR-FHSS) communication over sub-GHz and 2.4GHz Industrial, Scientific and Medical (ISM) bands as well as licensed S-Band for satellites. It integrates a Cloud-native multi-constellation global navigation satellite system (GNSS) scanner and a passive Wi-Fi MAC address scanner, both leveraging Semtech’s LoRa Cloud™ services.
The LR1120 is designed to comply with the physical layer requirements of the LoRaWAN® standard specification released by the LoRa Alliance®, while remaining configurable to meet different application requirements and proprietary protocols.
