Path Loss Models for Wireless Access Network Systems Using High Frequency Bands

Abstract

To design coverage areas for wireless communication systems and evaluate the performance of the systems, it is necessary to develop a path loss model that can be used for the systems' frequency bands. The fifth-generation mobile communication system (5G) is expected to use high frequency bands above 6 GHz. Therefore, developing a path loss model for wireless access communication systems using high frequency bands has become a pressing issue. NTT Access Network Service Systems Laboratories has developed path loss models for the 20-40 GHz bands that are suitable for use scenarios of mobile phones and wireless local area networks. This article introduces the developed models.
