Designed to help extend IoT connectivity range with multiprotocol support for AI applications, Semtech's new LoRa Gen 4 transceivers extend the capabilities of the LR2021 into cost-optimized and application-specific solutions. The LR2022 dual-band and LR2012 sub-GHz transceivers leverage fourth-generation LoRa performance across a variety of deployment scenarios, offering optimized feature sets and price points.
The expanded Gen 4 portfolio is able to deliver up to 2.6-Mb/s data rates while maintaining power efficiency and range performance. This helps create scalable solutions that support everything from AI-powered edge applications requiring image-transfer capabilities to traditional sensor networks prioritizing cost-optimized connectivity. Features include multi-PHY capability for legacy system integration, dual-band operation for global coverage with a single SKU, or sub-GHz radio with best-in-class link budget
LoRa Gen 4 transceivers deliver data rates comparable to those achieved by short-range protocols, while extending LoRa capabilities with superior link budget and range. They also offer improved resilience against environmental challenges and interference for industrial environments or extended outdoor deployments.
Among their other features are enhanced LoRa and frequency-shift-keying (FSK) radio performance for more efficient channel activity detection (CAD), support for multiple spreading factors (SFs), and round-trip time of flight (RTToF). Furthermore, they maintain backward compatibility with over 450 million deployed LoRa devices.
The LR2021 multiprotocol transceiver is compatible with LoRa, LoRaWAN, and fast long-range communication (FLRC) at data rates up to 2.6 Mb/s, while the LR2022 is designed as a dual-band solution to address applications that require global sub-GHz, 2.4-GHz, or satellite connectivity. The LR2012 targets sub-GHz operations, delivering enhanced sensitivity down to –142 dBm.
