Abstract :
The authors present novel site-specific propagation prediction methods for emerging personal communication system (PCS) services which will offer high capacity in urban settings. The propagation prediction models, composed of 3-D diffraction and ray tracing, are being implemented as software tools on SUN computer workstations. A geographical information system software package is being used to interface building and terrain data with the propagation prediction programs. Early work at Virginia Tech´s Mobile and Portable Radio Research Group shows that the predicted signal strengths are within a few decibels of average measured signal strengths for some test cases
