Outdoor Propagation
Detailed Description
This is an example of how to directly carry outdoor propagation. The full example is distributed with the installation.#include <stdio.h> #include <string> #include <iostream> #include "outdoor_propagation.h" #ifndef API_DATA_FOLDER #define API_DATA_FOLDER "../../api/winprop/data/" #endif // !API_DATA_FOLDER int main(int argc, char** argv) { int Error = 0; WinProp_ParaMain GeneralParameters; WinProp_Antenna Antenna; WinProp_Callback Callback; WinProp_Result Resultmatrix; WinProp_RayMatrix RayMatrix; WinProp_Propagation_Results OutputResults; // name of .opb database without extensions const char* my_opb_database = API_DATA_FOLDER "outdoor/City"; /* ------------------------ Initialisation of parameters ----------------------*/ WinProp_Structure_Init_ParameterMain(&GeneralParameters); WinProp_Structure_Init_Antenna(&Antenna); WinProp_Structure_Init_Callback(&Callback); WinProp_Structure_Init_Result(&Resultmatrix); WinProp_Structure_Init_RayMatrix(&RayMatrix); WinProp_Structure_Init_Propagation_Results(&OutputResults); /*---------------- Definition of scenario -------------------------------------*/ /* Definition of general parameters. */ GeneralParameters.ScenarioMode = SCENARIOMODE_URBAN; // Urban prediction GeneralParameters.PredictionModelUrban = PREDMODEL_UDP; // Use Dominant Path Model /* Definition of prediction area. */ GeneralParameters.UrbanLowerLeftX = 100.0; GeneralParameters.UrbanLowerLeftY = 100.0; GeneralParameters.UrbanUpperRightX = 2200.0; GeneralParameters.UrbanUpperRightY = 3200.0; /* Copy coordinates to prediction area of second model (not yet used) */ GeneralParameters.RuralLowerLeftX = GeneralParameters.UrbanLowerLeftX; GeneralParameters.RuralLowerLeftY = GeneralParameters.UrbanLowerLeftY; GeneralParameters.RuralUpperRightX = GeneralParameters.UrbanUpperRightX; GeneralParameters.RuralUpperRightY = GeneralParameters.UrbanUpperRightY; double PredictionHeight = 1.5; /* Size of matrix with results. */ GeneralParameters.Resolution = 10.0; // Resolution in meter GeneralParameters.NrLayers = 1; // Number of prediction heights GeneralParameters.PredictionHeights = &PredictionHeight; // Prediction height in meter /* Building vector data and topography. */ GeneralParameters.BuildingsMode = BUILDINGSMODE_UDP; // load a .opb database (urban + topography) sprintf(GeneralParameters.BuildingsName, "%s", my_opb_database); // Vector database in WinProp format /*--------------------------- Definition of antenna ---------------------------*/ /* Position and configuration. */ Antenna.Id = 1; Antenna.SiteId = 1; Antenna.Longitude_X = 1100.0; Antenna.Latitude_Y = 2100.0; Antenna.Height = 20.0; Antenna.Power = 43.0; // Power in dBm Antenna.Frequency = 1800.0; // Frequency in MHz sprintf(Antenna.Name, "%s", "Antenna 1"); /* Definition of outputs to be computed and written in WinProp format. */ GeneralParameters.OutputResults = &OutputResults; sprintf(OutputResults.ResultPath, "%s", API_DATA_FOLDER "output/OutdoorArea_Output"); // Output data directory OutputResults.FieldStrength = 1; OutputResults.PathLoss = 1; OutputResults.StatusLOS = 1; OutputResults.RayFilePropPaths = 1; OutputResults.StrFilePropPaths = 1; /*-------------------------- Callbacks ----------------------------------------*/ Callback.Percentage = CallbackProgress; Callback.Message = CallbackMessage; Callback.Error = CallbackError; /*----------------------- Compute outdoor prediction --------------------------*/ Error = OutdoorPlugIn_ComputePrediction( &Antenna, &GeneralParameters, NULL, 0, NULL, NULL, NULL, NULL, &Callback, &Resultmatrix, &RayMatrix, NULL, NULL); /*----------------------- Do something with results ---------------------------*/ if (Error == 0) { const char* Filename = API_DATA_FOLDER "output/Results.txt"; write_ascii(&Resultmatrix, Filename); } else { /* Error during prediction.
