HOPERF LoRa module RFM95W-868S2R

The RFM95W/96W/98W incorporates the LoRa TM spread spectrum modem which is capable of achieving significantly longer range than existing systems based on FSK or OOK modulation. With this new modulation scheme sensitivities 8 dB better than FSK can be achieved with a low-cost, low-tolerance, crystal reference. This increase in link budget provides much longer range and robustness without the need for external amplification. LoRa TM 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. 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. The RFM95W/96W offers bandwidth options ranging from 125 kHz to 500 kHz with spreading factors ranging from 6 to 12, RFM98W Band3 module options ranging from 20.83kHz to 125kHz with spreading factors ranging from 6 to 12, The RFM95W covers the higher UHF bands.
