LoRa1120:160mW Multi-Band Wireless Communication Module

LoRa1120:160mW Multi-Band Wireless Communication Module

LoRa1120 adopts Semtech's LR1120 chip, an ultra-low-power module designed specifically for global geolocation applications. It supports multi-band LoRa and long-range frequency hopping spread spectrum (LR-FHSS) communication, operating in the sub-GHz and 2.4GHz industrial, scientific, and medical (ISM) bands, as well as the S-band authorized for satellite communication. The module integrates a cloud-native multi-constellation Global Navigation Satellite System (GNSS) scanner and a passive WiFi MAC address scanner, both of which are serviced through Semtech’s LoRaCloud™. The LR1120 complies with the physical layer requirements of the LoRaWAN standard specification released by the LoRa Alliance while maintaining configurability to meet various application and proprietary protocol needs.
