Indoor Propagation Modeling for Radiating Cable Systems in the Frequency Range of 900-2500 MHZ

Abstract

Abstract-The aim of this paper is to propose and evaluate a semiempirical propagation modeling for radiating cable used in indoor environments. This propagation modeling takes into consideration propagation mechanisms such as reflections, penetration loss and cable termination that result from a particular environment, as well as specific cable paths that actual propagation models for radiating cable systems have not considered. The proposed modeling is carried out using three different propagation models and has been experimentally validated by sets of measurements performed in a university building in the frequency range from 900 MHz to 2.5 GHz. A careful selection of the data sets validates the robustness of the proposed model. The results show a mean of the error less than 1 dB while the standard deviation is between 2.2 dB and 4.6 dB in all cases. To the best of our knowledge, this is the first time such a robust modeling for radiating cable operating between 900 MHz to 2.5 GHz has been presented.

Tuning Selection Impact on Kriging-Aided In-Building Path Loss Modeling

“…Measurement-based models employ radio measurements to perform model fitting and model validation through tuning and testing datasets, respectively. In most studies, these datasets are selected from the corresponding measurements according to a desired ratio a/b that is based on random sampling [8], [9], i.e., an a% for tuning the model and a b% for testing the model. In [10] the authors analyze the following approaches: what happens when the method selection of tuning dataset varies in order to select the right one to get the The authors wish to acknowledge the support received from the National Council of Science and Technology CONACYT, through the student scholarship number 746015.…”
