Interactive coverage region and system design simulation for wireless communication systems in multifloored indoor environments: SMT Plus

This paper presents an approach to modeling indoor wireless communication systems using statistical path loss prediction calculations. The statistical calculations work with an indoor building database to accurately predict path loss and interference (C/I) values with much less computational complexity than brute force ray tracing methods. This paper describes the algorithms and illustrates typical coverage contours provided by the resulting indoor planning tool called SMT Plus^TM. This paper also describes techniques under development to incorporate measurements in order to further improve the accuracy of the statistical models, as well as several future directions for SMT Plus
