Industrial environment, smart home, and data acquisition...
The LR1121 can communicate with SX126X, SX127X, and SX128X series, which is still compatible with previous LoRa products after upgrading, and provides higher power efficiency and longer transmission distance.
The LR1121 supports both LoRa Chirp Spread Spectrum (CSS) and Frequency Hopping Spread Spectrum (FHSS) technologies, with modulation coverage across Sub-GHz, S-band, and 2.4GHz ISM frequency bands. Suitable for applications in industrial, agricultural, smart city, and satellite IoT scenarios.
This frequency band is globally license-free and is ideal for short-range, high-speed data transmission
