MSRFM-a prediction tool for radio system design

The development and evolution of a versatile radio propagation and performance modeling system known as MSRFM (multisite RF model) is described. The modeling system consists of four major functional classifications: (a) the propagation model (MSRFM), (b) database utilities, (c) analysis programs, and (d) a plotting program (MSPLOT). Database and device support utilities are used initially to digitize and process terrain and clutter data. Output from MSRFM is in the form of predicted signal level. The accuracy and usefulness of MSRFM has been field-proven through its´ use in the design of a large number of cellular systems in North, South, and Central America and numerous countries throughout the eastern hemisphere. Data taken from field measurements made in a wide variety of environments (ranging from jungle to urban and open areas) have been used in an on-going manner to further improve the accuracy of the calculation methods
