Overview
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.

The devastation caused by wildfires makes headlines every year and continues to worsen. Wildfires cause not only enormous humanitarian and economic hardship but also have a massive environmental impact. In addition to destroying animal and plant life, wildfires emit between 5 and 30 tons of carbon per hectare. All of the land that burns globally in an average year adds 13 billion metric tons of additional carbon to the atmosphere annually, a significant contribution to climate change.
