Semtech’s LR1120: An Industry First
Integrating a LoRa® Edge transceiver, Semtech’s LR1120 is the industry’s first ultra-low power, highly integrated multi-technology geolocation, Cloud-ready solution. Based on Semtech’s LR1110, the LR1120 features enhanced connectivity with 2.4 GHz LoRa modulation. Optimal for geolocation applications, the LR1120 enables affordable and simplified asset management.
The LR1120 supports multi-band and long-range Frequency Hopping Spectrum (LR-FHSS) communication over sub-GHz, 2.4 GHz for Industrial, Scientific, and Medical (ISM) bands, and licensed S-Band for satellites. Integrating a multi-constellation global navigation satellite (GNSS) scanner and passive Wi-Fi Access Point address scanner, the LR1120 complies with the physical layer requirements of LoRaWAN® standard specifications and provides flexibility to meet a wide range of applications.
