Abstract—Recently, the interest in Internet of Things (IoT) has been increasing. Thus, it is necessary to study on the coexistence between IoT devices and other radio communication services for the efficient use of limited frequency resource. In this paper, the interference of the IoT device using Wi-Fi HaLow to the Long Term Evolution (LTE) User Equipment (UE) was studied through Minimum Coupling Loss (MCL) method and Monte Carlo (MC) method. As a result, the separation distance and the number of acceptable Wi-Fi HaLow devices based on Duty Cycle (DC) were obtained to protect the LTE UE from the interference of Wi-Fi HaLow device.
Index Terms—Interference, Wi-Fi HaLow, LTE UE, MCL, MC, separation distance, DC
