Results of mobile channel sounding measurements in the 4.9 GHz public safety band

This paper describes a channel sounding system and a corresponding data processing method for the characterization of wireless channels in the 4.9 GHz public safety band. The equipment and subsequent processing enable high-resolution estimation of propagation delay, Doppler frequency shift, and direction-of-arrival (azimuth and elevation) associated with multipath signal components. Results are shown that verify the proper functioning of the equipment and parameter estimation method.
