California-based Semtech has expanded its LoRa Plus family with the LR2022 and LR2012 transceivers, both now in production.

The two devices extend the LoRa Plus family to address a full range of IoT application requirements from sub-GHz deployments to multi-band global tracking with satellite connectivity, bringing the LoRa Plus portfolio to three production-ready transceivers.

The LR2022 and LR2012 share the same fourth-generation LoRa IP core as the LR2021, offering backwards compatibility with LoRaWan, LR-FHSS and legacy OOK devices. The devices feature radio performance with best-in-class sensitivity and extended data rates up to 125kbit/s for LoRa and 2Mbit/s for FSK applications. This throughput enables high-speed burst data transmissions within a low-power envelope, supporting large file transfers including images, audio, and firmware over-the-air updates. The devices also support use cases requiring low latency in proprietary wireless protocols.

An early customer is German meter maker Zenner. “Zenner selected Semtech’s LR2012 LoRa Plus transceiver for our stealth reader meter interface unit for AMR and AMI due to its superior LoRaWan performance, backwards compatibility with legacy OOK and support for LR-FHSS enabling scalable satellite connectivity,” said Rich Sanders, president of Zenner (zenner.com) in the USA.

Another user is German firm Engelmann Sensor. “For our next-generation metering, we wanted a LoRaWan platform that could fully leverage the latest LoRa innovations,” said Tobias Knop, team leader for firmware development at Engelmann Sensor (www.engelmann.de). “Semtech’s LR2012 delivers exactly that at the right price point, making it the ideal choice to power our roadmap.”

The wireless IC portfolio comprises the LR2021 (www.semtech.com/products/wireless-rf/lora-plus/lr2021) multi-band, multi-protocol transceiver with FLRC 2.6Mbit/s for edge AI; LR2022 (www.semtech.com/products/wireless-rf/lora-plus/lr2022) multi-band, single-hardware-design transceiver for global terrestrial and non-terrestrial networks; and LR2012 (www.semtech.com/products/wireless-rf/lora-plus/lr2012) sub-GHz transceiver for traditional low-power wireless and LPWAN.

“With the LR2022 and LR2012 now in production, there is a LoRa Plus chip for multiple IoT applications from sub-GHz sensor nodes to global multi-band trackers with satellite connectivity to edge AI devices supporting multiple wireless protocols,” said Shahar Feldman, senior product marketing director at Semtech (semtech.com). “These devices share the same fourth-generation LoRa IP platform and unified software platform, backed by a global ecosystem of more than 500 million deployed LoRa devices.”
