The WSL305S transceivers SX127x feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. 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.
