Reasearch Of Indoor Coverage Prediction Based On LTE System

As the increase of the use of the indoor planning system in buildings like factory, office, exhibition hall and related environment, a variety of efficient propagation models has been proposed. In order to solve the problem of indoor distribution, the study of indoor propagation loss model and indoor optimization algorithm is very necessary.This article mainly discusses the indoor propagation loss model and indoor optimization algorithm. In the aspect of indoor propagation loss model, we mainly study the experience model and deterministic models,and we compare their time complexity after that. Then we compare the field intensity distribution of different experienced models in different scenarios. The result is that in empty scenario, the line-to-sight model or Keen-Motley model fit the scenario, however, when the scenario become more complex, Keen-Motley model seems more suitable.Then we studied and compared the indoor optimization algorithms.We mainly compared traditional algorithms and NSGA-II in efficiency and final results. Finally, we get the answer that both from the efficiency and the optimized result, the NSGA-II is better than the traditional algorithms.
