Strong Communication Compatibility

The LR2021 can communicate with LR1121, SX126X, SX127X, and SX128X series, maintaining backward compatibility with existing LoRa products after upgrades, and provides higher power efficiency and longer transmission distance.

Dual Spread Spectrum Modulation for Complex Environments

The LR2021 integrates both LoRa Chirp Spread Spectrum and Long Range Frequency Hopping Spread Spectrum technologies, supports Sub-GHz, 2.4 GHz ISM band, and 1.5 ~ 2.5 GHz licensed tri-band coverage, enabling both terrestrial IoT and satellite IoT communication requirements. It is suitable for applications in industrial, agricultural, smart city, and satellite IoT scenarios.

ISM Band

This frequency band is globally license-free and is ideal for short-range, high-speed data transmission
