Semtech Corporation has unveiled the LR2021, the inaugural chip in the cutting-edge LoRa Plus family. This innovative transceiver, equipped with a fourth-generation LoRa IP, provides support for both terrestrial and SATCOM networks across the Sub-GHz, 2.4 GHz ISM bands, and licensed S-band. Backward compatibility with previous LoRa devices ensures seamless integration with LoRaWAN, while expanded physical layer modulations enable fast long-range communication (FLRC) and compatibility with various low-power wireless protocols like Amazon Sidewalk, Meshtastic, and more.The LR2021 caters to the growing demand for AI-enabled edge devices that prioritize low power consumption, extended range, and enhanced penetration capabilities. It facilitates sensor data transmission for applications such as gunshot detection, glass break sensing, and fall detection, all while running on small batteries for extended periods. With a maximum data rate of 2.6 Mbps, it enables seamless audio streaming and image transfer, boasting exceptional link budget and efficiency. The state-of-the-art RF and analog architecture allows for multi-region deployment through a single-SKU design, reducing BOM costs, PCB footprint, and power consumption compared to previous LoRa transceivers.
Key features of the LR2021 include support for terrestrial and non-terrestrial networks, Sub-GHz, 2.4GHz ISM, and licensed S-band radio frequencies, multi-PHY compatibility for LP wireless protocols, various modulations including FLRC and LoRa, and enhanced sensitivity down to -142 dBm at SF12/125 kHz. The transceiver’s innovative design eliminates the need for a temperature-compensated crystal oscillator (TCXO) and offers increased frequency offset tolerance, ensuring robust performance across different environments.
Semtech plans to make the LR2021 available for customer sampling in April 2025. Industry partners and customers can experience Semtech’s latest innovations and engage with technical experts at upcoming events such as Embedded World in Nuremberg, India Smart Utility Week in New Delhi, and DistribuTECH in Dallas.
