Analysis of Propagation Loss in Urban Microcells at 1.9 GHz and 5.8 GHz

Abstract

Continuous Wave (CW) measurements carried out in downtown Ottawa were used as the basis for comparisons between propagation loss at frequencies near 2 GHz and 6 GHz in urban microcellular environments. The difference (dB) was found to have a Gaussian distribution over urban microcellular coverage areas. To provide physical explanations for measured results, modelling was carried out at 2 GHz. During this process, low complexity models reported for other parts of the world were evaluated against the measurements, which were made in an urban area, which is typical of North America. Comparison of selected models with measurement data resulted in median root mean square (rms) modelling errors that ranged between 4 dB and 7 dB
