Propagation loss prediction in the urban environment with rectangular grid-plan streets

To design the MultiGain Wireless system constructed by Tadiran Telecommunication, it is essential to investigate the propagation characteristics and cell coverage of urban/suburban radio channels. A two-dimensional crossing-waveguide model is proposed which is based on the preliminary results obtained from the two-dimensional waveguide model used in the investigation of radio wave propagation along the street in line-of-sight (LOS) conditions. The redistribution of wave energy near each intersection inside the rectangular grid pattern of crossing streets depends on the processes inside each waveguide and on the parameters of brokenness, that is, on building distribution in each radial and perpendicular street waveguide inside the grid.
