Use of wireless communication protocol LoRa for IoT system needs these days growing. The IoT system itself is increasingly extends to various fields and needs. However that way the IoT system needs a protocol communication with a wide range but also must Can be used by many devices at the same time. This study will examine the effect of spreading factor on the LoRa wireless communication protocol against packet collisions found.

End on research This will convey suggestions for using the protocol LoRa wireless communication with configuration a spreading factor that suits the needs of each IoT system. Where if the higher the spreading the factor, the wider the reach the network but the more packets the collision. Conversely, if the lower the spreading the factor will be the narrower the network coverage but the less packet collisionnya. Study It uses MatLab software as a simulation tool LoRa wireless communication protocol.
