This paper presents several models of the literature applied to a wooded cross-road configuration in microcellular context at 1.9 GHz. A new UTD-based model is detailed, in which two modes of propagation are taken into account: direct and lateral waves. Simulations are compared with measurements.
The frequency bands, presently used by space telecommunications systems, are saturated, hence the need for using higher frequencies (EHF). However, for millimetre waves, the atmospheric propagation of electromagnetic waves is more perturbed than at lower bands. Precipitation, clouds and gases are responsible for that. The contribution of the melting layer, in terms of attenuation, is also no more...
