Abstract

The design of future-generation mobile communication systems depends critically on the suitability of path loss prediction methods and their suitability to various regions. To investigate the radio channel behavior, experimental measurements in the 1.8 GHz band were conducted in the dense urban regions of New Delhi for six GSM base stations. Path loss exponents and break point distances have been deduced, and observed results have been compared with various prediction methods, and their standard deviations have been presented. Measured regression line exhibited lowest standard deviations followed by rooftop propagation method compared with Cost 231 Hata and Cost 231 Walfisch–Ikegami (WI) prediction methods. Variation of observed results has been explained in terms of vertical and horizontal propagation mechanisms which is the novelty of this paper.
