Industrial environment, smart home, and data acquisition...
Ā
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.
Ā
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.
Ā
This frequency band is globally license-free and is ideal for short-range, high-speed data transmission
