LR1278NA-G SX1278 Lora Module
1. The LR1278NA-G module is designed based on SX1278. The SX1278 incorporates the LoRaTM spread spectrum modem which is capable of achieving significantly longer range than existing systems based on FSK or OOK modulation.
2. At maximum data rates of LoRaTM the sensitivity is 8dB better than FSK, but using a low cost bill of materials with a 20ppm XTAL LoRaTM can improve receiver sensitivity by more than 20dB compared to FSK.
3. LoRaTM also provides significant advances in selectivity and blocking performance, further improving communication reliability.
4. 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. Standard GFSK, FSK, OOK, and GMSK modulation is also provided to allow compatibility with existing systems or standards such as wireless MBUS and IEEE 802.15.4g.
