Description

The ultimate guide to modeling the propagation of radio waves by a leading expert, a professor at Polytechnic University of New York.

- Top techniques and innovative propagation prediction models.
- Detailed comparisons with real measurements.
- Multipath models, wave propagation, diffraction, and other phenomena.
- A groundbreaking analysis of path loss in communication with mobile devices in urban areas.

Specifically, the book includes the following:
- The concept of cellular communication and the need for propagation prediction (spatial reuse, linear cells as an example of FDMA system spectrum reuse, hexagonal coverage cells, etc.).
- Examination of characteristics observed in propagation channels (measurements of narrowband signals, fast fading, shadow fading, separation of shadow fading from distance dependence, tilt-slope models as a function of distance for macrocells, effects of road geometry, etc.).
- Propagation, reflection, and transmission of flat waves (wave levels in unbounded areas, reflection of flat waves at boundaries, incidence of flat waves on dielectric layers).
- Antennas and radiation (radiation of spherical waves, receiving antennas, reciprocity and path gain or loss, two-ray models for propagation above flat ground surfaces, propagation in line of sight in urban canyons, cylindrical waves).
- Diffraction on edges and corners (the local nature of propagation, diffraction of flat waves by absorbing screens, diffraction for other edges and for oblique incidence, diffraction of spherical waves, diffraction by multiple edges).
- Wave propagation on ground with buildings (modeling propagation above arrays of low buildings, approaches to calculating PG1 reduction of fields above roofs, incidence of flat waves for macrocell predictions, incidence of cylindrical waves for microcell system predictions).
- Shadow fading and the effect of ground morphology and trees (statistics of shadow fading, modeling the effect of ground morphology and the effect of trees).
- Propagation prediction in specific locations (in outdoor areas using a two-dimensional building database, in two dimensions for a road grid in Manhattan, in outdoor areas using 3D building databases, predictions for specific indoor locations).
