GENERAL PURPOSE CALCULATOR FOR OUTDOOR PROPAGATION LOSS
For seven different propagation models, this calculator gives the propagation loss
in dB for the distance in kilometers that is entered by the user.
The calculation also is a function of frequency and antenna heights, and
the user may enter values for these parameters. The models for calculating
the propagation loss that are included are
-
the CCIR model, taking the parameter "percentage of buildings"
-
four cases of the Hata model that correspond respectively to "open", "suburban", "small
city", and "large city" terrain
-
two cases of the Walfisch-Ikegami model that correspond respectively to line-of-sight
(LOS) and non-LOS situations and that take parameters that describe the
building heights, street width, etc.
The calculator was originally developed as an Excel spreadsheet application by Leonard
Miller. New C++ and TCL pop-up versions were developed by Tim Hall,
as was a command-line executable file that can be run in a DOS window.
