Wireless Network Coverage Simulation, Measurement, and Propagation Model Correction

In the mobile communication system, the effective coverage of radio waves and the environmental adaptability of the propagation model largely reflect the construction quality of the operator’s wireless network. In order to evaluate the performance of the wireless network, this paper first conducts a coverage simulation on the existing LTE network, and then evaluates the performance difference between the simulation and the actual measurement data. In order to obtain the optimal propagation model of the measurement environment, we compared the ME (Mean Error), RMSE (Root Mean Square Error) and ESTD (Error Standard Deviation) of the predicted value and the measured value of Okumura-Hata model, SPM model, and Cost231-Hata model. Finally, the TREENETs model was established on the basis of the SPM, and the optimal propagation model parameters in the measurement environment were obtained. The simulation, measurement, and propagation model correction methods in this paper may be used in the coverage performance evaluation of future B5G (Beyond 5G) networks and C-V2X (Cellular Vehicle-to-everything) networks, and provide new construction solutions and optimization suggestions for these wireless networks.
