The RFM98W transceivers feature the LoRaTM long-range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
Using Hope RF’s patented LoRaTM modulation technique RFM98W can achieve a sensitivity of over -148dBm using a low-cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier yields an industry-leading link budget making it optimal for any application requiring range or robustness. LoRaTM also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity, and energy consumption.
