A New Integral Propagation Model for Radio Coverage Prediction in Indoor Environments

摘要

This paper presents an integral model for radio coverage prediction in indoor environments. The proposed method considers the mapping relations between the complex propagation mechanisms and structured indoor environments in a new point of view. The coverage problem in indoor environment is solved by those mapping relations under some a priori constraints, and the complicated propagation-prediction problem is reduced to solving a system of large-scale integral equations. With the same simulation environment, the results show that the accuracy of integral model is similar to Finite-difference Time-domain (FDTD) method, but the computing efficiency is at the same level with empirical model.
