A low cost communication alternative could allow better V2I communications. In this way, the alternative would complement the 5G technology, driving the reliability of the system up. For that purpose, a selection of low cost technologies, which cover a short/middle range, was carried out. Then, theirs capabilities were tested and compared by means of a test-bed, achieving knowledge about theirs strengths and weaknesses. The final goal is to apply the technology in a real proof of concept.
