The current frequency allocation methods always use measured data to analyze interference and do not directly consider the disturbance intensity which is directly related to the distance, azimuth, relative position, and other factors. During the measuring period, many problems may occur such as not enough sampling points, barriers, base station failure or other problems caused by accidental factors. Such problems affect the data accuracy and the same or adjacent channel frequency allocation results. Same and adjacent channel interference then affects the network performance. Therefore, factors such as distance, azimuth, and relative position of the network should be considered for adjacent channel interference verification and optimization.
