Feasability of Bluetooth 5.0 connectionless communications for I2V applications

Vehicle communications are one of the pillars of the development of Intelligent Transport Systems. This is a complex scenario, where several types of entities interact with each other, using a range of communication infrastructure. In this area there are several applicable technologies, with different advantages and disadvantages. Therefore, flexible and ubiquitous communication, capable of using any communication type, will allow Smart vehicles to use the most appropriate one to improve traffic movement systems. Although the use of Bluetooth has been considered in this field, it has normally been done in intra-vehicle communications, or if it has been done outside this field, for inter-vehicle communications, it has been done based on standard 4.2 or earlier versions. The Bluetooth BLE 5.0 standard has features that allow the use of this technology in previously unimaginable scenarios; in particular, the increase in range, and greater robustness in communications allowing the analysis of its use as an infrastructure to vehicle network. The preliminary results obtained demonstrate this viability and the potential of this technology in this field.
