N2 - This paper clarifies cell coverage improvement by bandwidth control corresponding to radio channel fluctuation in multi-band IoT systems with spectrum sharing. The results by computer simulation show that the bandwidth control can improve the coverage of an interfering multi-band system by 10% at the use rate of 70% and the inter-system power rate of 20 dB when an interfered system uses the frequency band of third-order inter-modulation distortion caused by the interfering system. The results also show that the usable bandwidth rate to achieve the required coverage can be improved by up to 12%.
