The chip works on earth and satellite networks, uses many frequencies, sends data fast, supports many wireless types, and helps devices run longer and reach farther.
Semtech Corporation, a semiconductor, IoT systems, and cloud connectivity services provider, introduced the LR2021, the first chip in the LoRa Plus family. Using fourth-generation LoRa IP, the transceiver supports terrestrial and SATCOM networks in the Sub-GHz, 2.4 GHz ISM bands, and licensed S-band. The transceiver is backwards compatible with previous LoRa devices, ensuring LoRaWAN compatibility. It also supports physical layer modulations for fast, long-range communication (FLRC). When used with third-party stack offerings, it is compatible with wireless protocols including Amazon Sidewalk, Meshtastic, W-MBUS, Wi-SUN FSK, and Z-Wave.
The chip addresses the demand for AI-enabled edge devices requiring low power, extended range, and penetration. It supports sensor data transmission for applications like gunshot detection, glass break sensing, license plate recognition, and fall detection, operating on small batteries for years. With a data rate of up to 2.6 Mbps, it enables audio streaming and image transfer with link budget and efficiency. The RF and analogue architecture supports multi-region deployment via a single-SKU design, while integration reduces BOM costs, PCB footprint, and power consumption compared to previous LoRa transceivers.
Some of the key features of the LR2021 include:
- Works on earth, satellite networks, Sub-GHz, 2.4 GHz, and licensed S-band.
- Supports many wireless protocols with extra software.
- Fast data rates: FLRC up to 2.6 Mbps, LoRa up to 200 kbps, and others.
- It works worldwide with one design, so no switches are needed.
- It transmits from +22 dBm to -10 dBm and uses low power.
“The LR2021 revolutionises IoT connectivity by addressing key challenges for AI-powered deployments of any scale,” stated Shahar Feldman, senior product marketing director for LoRa ICs at Semtech. “Whether for European utilities requiring both LoRaWAN and W-MBUS, North America utilities with LoRaWAN and Wi-Sun FSK, or security systems and smart home applications necessitating long-range LoRa connectivity with protocols such as Z-Wave, this single-chip solution simplifies complexity and enhances performance. LoRa data rates are now increased to support an extended range of applications, from small payload sensor data to high-definition image transfer, facilitating the development of a new generation of intelligent IoT devices.”
