Large-Scale Propagation Analysis and Coverage Area Evaluation of 3G WCDMA in Urban Environments Based on BS Antenna Heights
The design of an efficient cellular system requires a detailed understanding of propagation characteristics of a mobile radio channel. A signal propagating through a channel undergoes two kinds of variations; large-scale and small-scale. Path loss is generally the most important parameter predicted by large-scale variations. In this paper a Large-scale propagation model is described for urban environments, to evaluate the coverage area of 3G WCDMA cellular system based on BS antenna heights. COST 231 Hata model is presented for large-scale analysis of WCDMA systems. The results are evaluated with different parameters; coverage radius, antenna heights and Eb/N0. It is observed that, path loss decreases from 167.55 dB to 155.67 dB as the BS antenna height increases from 30 m to 120 m for 8 km coverage radius in a WCDMA system for urban environments.
