Semtech,a provider of semiconductors, Internet of Things (IoT) systems and cloud connectivity services, has introduced the LR2021, the first chip in the LoRa Plus family.
Incorporating a fourth-generation LoRa IP, the transceiver supports both terrestrial and SATCOM networks in the Sub-GHz, 2.4 GHz ISM bands and licensed S-band.
The transceiver has been designed to be backward compatible with previous LoRa devices and, in addition, it features expanded physical layer modulations for fast long-range communication (FLRC) and is compatible with various low-power wireless protocols including Amazon Sidewalk, Meshtastic, W-MBUS, Wi-SUN FSK, and Z-Wave when integrated with third-party stack offerings.
The LR2021 is intended to address the demand for AI-enabled edge devices requiring low-power, extended range and penetration. It supports sensor data transmission for applications like glass break sensing, license plate recognition, and fall detection, while operating on small batteries for years.
With a data rate of up to 2.6 Mbps, it enables audio streaming and image transfer with an impressive link budget and efficiency. The RF and analogue architecture supports multi-region deployment via a single-SKU design, while high integration reduces BOM costs, PCB footprint and power consumption compared to previous LoRa transceivers.
Key features of LR2021 include:
