Statistical Analysis of an Outdoor mmWave Channel Model at 73 GHz for 5G Networks

Abstract

In recent years, an increasing interest in the millimeter wave (mmWave) communications plays a vital solution for the growing demands of the data and speed. As a vast unused spectrum, mmWave is expected to handle a key role in the access network of the fifth generation (5G) mobile technologies. Despite its ability to provide higher transmission rate and spread spectrum capability, mmWave suffers from several major drawbacks such as high attenuation and sensitivity due to its weather dependency which causes the modeling of an mmWave channel to be very challenging. In this research, we investigate a statistical analysis of an outdoor channel in 73 GHz for access network of an urban micro cell. A well known mmWave channel modeling simulator NYUSIM is used for both LOS and NLOS scenarios. Simulation scenarios consider some crucial network parameters such as angle of arrival, angle of departure, power delay profiles, and path loss to characterize an mmWave channel in the 73 GHz E band. These investigations may be utilized to demonstrate the potential of 73 GHz mmWave band and its suitability for the 5G outdoor networks.
