Importance of the effects of spreading factor interference in collisions LoRa radio interface

The Internet of Things (IoT) is a concept in which everyday objects and devices are equipped with connectivity, allowing them to exchange information. In recent years, interest this has increased led the creation numerous applications interested customers. Long Range (LoRa) technology part technologies that support IoT equipment LoRa popularity due its ability work low power consumption, very important factor when referring devices, as they dependent on your battery. work, we study importance interference Spreading Factor (SF) collision effects for LoRaWAN Radio Interface. To achieve intended objectives, will start by making an in-depth some types Wireless Sensor Networks (WSN) networks. Next, carry out practical tests outdoor environment. More than thousand measurements were made between gateway device, be explained throughout paper. These used compare real values theoretical ones SF collisions.
