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

A two-dimensional crossing waveguides model is proposed based on the preliminary results obtained from the 2D-waveguide model developed previously for the investigation of radiowave propagation along streets in line of sight (LOS) conditions. This model is expected to give a satisfactory theoretical treatment of the channeling phenomenon and thus present the real field strength distribution between streets and their intersections. Comparison between theoretical prediction and experimentally obtained data suggests that with an accuracy of (3-5) dB, a 2D-crossing-waveguide model can be used for microcell coverage and range predictions in urban and suburban areas with rectangular grid-plan streets.
