LoRa module(KM26-R)
Overview:
Lora provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
It also achieves a sensitivity of over -148dBm with low cost. The high sensitivity combined with the integrated +20dBm power amplifier yields industry leading link budget making it optimal for any application requiring range of robustness.
Lora 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.
