Impacts of environment and antenna height on angular spread of radiowave propagation in a city street microcell

Model based results of impacts of environment and base station antenna height on RMS angular spreads of radiowave propagation are shown. The impact of environment is presented in terms of street width. Wider street width results in larger RMS azimuth angular spread and smaller RMS elevation angular spread. No significant difference in RMS azimuth angular spread is noticed for different base station antenna heights. Higher base station antenna height results in larger RMS elevation angular spread. Both RMS angular spreads reduce as the mobile station gets further away from base station. In city street microcell, the RMS angular spread is correlated with the RMS delay spread.
