Wideband channel characterization at UHF band for LTE applications

Abstract

This paper presents the preliminary results obtained in two field tests, aimed to evaluate some important characteristics of a broadband radio channel operating in the UHF band. Such characteristics include: Selective and depolarization fading, impulsive noise intensity, path loss modeling and its variation due to the terminal antenna height and due the antenna polarization, and polarization discrimination at the terminal antenna. This analysis was intended to answer these critical issues, applicable to the LTE-450, a broadband radio access system based on the Long Term Evolution technology, to be deployed at the 450 MHz band.
