Abstract :
Field trial results for different scenarios (propagation conditions, antenna heights, distance from the access point, etc.) in the city of Cambridge (UK) with a broadband FWA operating system (3.5 GHz) are used to evaluate the predictions of a 3D ray tracing propagation model. The model is optimised for FWA operational scenarios and combines the deterministic ray tracing techniques with the Fresnel zone theory. Rays diffracted over foliage as well as buildings are considered. The analysis considers the propagation characteristics of the FWA radio channel and also, the accuracy of the presented deterministic propagation modelling approach. It is shown that simulation results follow the measurements with a mean error -0.11 dB and standard deviation 4.86 dB.
