Propagation Model Selection for Unmanned Ground Vehicles Communication Links

The paper presents results of a propagation test performed for a Unmanned Ground Vehicle wireless communication link. Tests were performed using Orthogonal Frequency Division Multiplexing signals generated by a Universal Software Radio Peripheral in two frequency ranges: 2.4 GHz and 4.4 GHz. Achieved results were compared with predicted signal level obtained from a Vehicles in Network Simulation framework. The propagation models parameters were adjusted to minimize errors between measured results and predicted values to achieve high fidelity simulation environment.
