Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Provided is a method for identifying radio signal transmission characteristics in a wireless communication system. The method may include: identifying a signal transmission site; identifying a signal reception site; finding an area where a tree is present between the signal transmission site and the signal reception site; checking characteristics of the crown of the tree and characteristics of the trunk of the tree; and examining transmission characteristics of a radio signal sent from the signal transmission site to the signal reception site on the basis of the characteristics of the crown and the characteristics of the trunk.
