Vehicular communications represent the novelty in road safety and improvement of traffic conditions, as they allow the exchange of appropriate data between vehicles or between vehicles and infrastructure (road side units). However, in such dynamic environment, a safe and reliable communication is very difficult to obtain. The most tested and appropriate technologies appear to be, in 2.4 GHz: Wi-Fi, Bluetooth and ZigBee, while in 5.8/5.9 GHz the FCC has allocated typical Dedicated Short Range Communication frequency band. However, for typical non-critical applications there is no need for expensive communications. There are several cheaper options, like ZigBee, Bluetooth or Wi-Fi. In this paper we have performed a series of analysis on Bluetooth technology, as the most common short distance communication and we have tested the possibility of transferring data in noisy Wi-Fi environment. The results obtained (in terms of handshake time) were assessed and conclusions regarding the possibility of implementing Bluetooth communications in vehicular environments have been formulated.
