The RFM95W/96W/98W transceivers feature the Lo-Ra TM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. Using Lo-Ra TM modulation technique RFM95W/96W/98Wcan achieve a sensitivity of over -140dBm using a low cost crystal and bill of materials.
The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. Lo-Ra TM also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range,
