LoRa module Node DL7612

The DL7612 incorporates the LoRa® spread spectrum modem which is capable of achieving significantly longer range than existing systems based on FSK modulation. At maximum data rates of LoRa® the sensitivity is 8dB better than FSK, but using a low cost bill of materials can improve receiver sensitivity. LoRa® also provides significant advances in selectivity and blocking performance, further improving communication reliability. For maximum flexibility the user may decide on the spread spectrum modulation bandwidth (BW), spreading factor (SF) and error correction rate (CR). Another benefit of the spread modulation is that each spreading factor is orthogonal - thus multiple transmitted signals can occupy the same channel without interfering. This also permits simple coexistence with existing FSK based systems.The DL7612 offer bandwidth options ranging from 7.8 kHz to 500 kHz with spreading factors ranging from 6 to 12, and covering upper UHF bands.
