Simple LoRa network was built to enhance the data throughput performance. Slotted Channel Activity Detection (CAD) carrier sense multiple access with collision avoidance (CSMA/CA) method was applied to LoRa network to avoid collision without sacrificing the data throughput. Experiment shows that the proposed CSMA/CA method keeps 100% packet delivery ratio with 4800 bps.
