Measurements of Communication Channel in Different Scenarios with the Channel Characterization Tool System

Nowadays, the wireless networks have an important role in the deployment of several means of transports, platforms and applications. In the particular case of roads and vehicle area, some ideas are starting gaining importance such as the autonomous vehicle. In order to reach this ambitious goal, the wireless networks are a strategic issue for the communication between vehicles (V2V) and between infrastructure and vehicles (V2I), generally known as vehicle-to-everything (V2X). In this current moment, the most deployed cellular network is LTE (Long Term Evolution), progressing to 5G technology. Because of this, this paper shows the measurement of the LTE technology and the phenomena that affects this technology at IP level. To reach this last goal, the on-site testing of a measurement system is needed allowing to quantify network impairments of a communication channel in a given road environment. In this paper, the system capable of measuring a communication channel is explained and it is shown how an on-site testing of the communication channel of a specific road has been measured in terms of the RTT network impairment. As well, the results of the measurement has been analysed and explained. Finally, some conclusions are presented.
