Application of GRASS in Mobile and Portable Communications

This paper discusses the application of GRASS iil the area of mobile and portable radio communications. The growing interest in wireless personal communications has fueled efforts to produce systems with better performance and increased capacity. A brief view of mobile communications is presented along with the motivation for this research. The role of GRASS in radio propagation prediction is discussed. GRASS is used to analyze spatial information as well as display the results graphically. The work done in interfacing and applying GRASS toward the development of an integrated radio propagation prediction tool is presented. Finally, directions for future work are noted, including tessellation algorithms and enhanced_ attribute storage facilities. The adaptability of GRASS combined with the technical capabilities of propagation prediction software promise an effective software tool for mobile communication system design. ·
