Path Loss and Delay Spread Characterization in a 26 GHz mmWave Channel Using the Ray Tracing Method

Abstract

The application of millimeter wave band is a promising technique to achieve the high rates requirements in the Fifth Generation (5G) of wireless communications. In Brazil, the frequency spectrum regulatory agency must use the 26 GHz band to mmWave applications in 5G. This paper presents results of a 26 GHz micro-cellular urban channel obtained from a 3D ray tracing simulation. The applied ray tracing simulation is based on the Shooting-and-Bouncing Rays (SBR) method, which considers reflected and diffracted rays. The considered scenario of simulation is based on the mapping of Manaíra and Jardim Oceania neighborhoods, seafront of João Pessoa city, Brazil. As results, are presented the characterization of the path loss exponent, shadow fading standard deviation and RMS delay spread statistics.
