Propagation results at 11 GHz for microcellular radio

Given the limited spectrum allocated to cellular mobile radio, we consider the use of frequency bands where larger bandwidth allocations may be feasible. A radio network of ‘microcells’ has been proposed for such bands. We have conducted a propagation experiment at 11 GHz to characterise such communication channels in various environments. Results are given here for rural and semiurban environments, where propagation is found to be dominated by interference between the direct ray and a roadway-reflected ray.
