ДОСЛІДЖЕННЯ ЗАВАДОСТІЙКОСТІ ТЕХНОЛОГІЇ LORAWAN

Proceedings of the international scientific conference " MODERN CHALLENGES IN TELECOMMUNICATIONS ", 2020
Research of interference noise immunity technology LoRaWAN  LoRaWAN is a promising low-power network technology (LPWAN). LoRaWAN is one technology that are less susceptible to noise and interference than other LPWAN protocols. This technology operates in the unlicensed range, which increases the chances of interference in the communication line.
