Abstract :
One of the key parameters of radiowave propagation characteristics is the temporal change in the surrounding environment. Here, we report the development of a system for measuring line-of-sight (LOS) centerline blocking and its use in measuring the path loss when the LOS centerline is blocked in LOS propagation in an urban environment with low base station antenna height. The results of statistical processing of path loss for when there is centerline blockage by vehicles and when there is no blockage are presented.
