Table 5: Commercial V2X devices currently on the market—Part III. Although the same manufacturer's RSU and OBU devices, the supported standards and protocols are practically identical, and these devices often differ in quantity and type of interfaces, power supply methods and casing and installation structures. For example, OBU's devices have CAN interfaces that can be connected to the vehicle's information systems to obtain various readings from the vehicle's integrated sensors. Meanwhile, RSU and mobile devices do not have such interfaces. Furthermore, the OBU devices are powered from 6V to 24V power supply, as this corresponds to the rated voltage of the vehicle battery. Meanwhile, the power supply of RSU devices comes through the power-over-ethernet (PoE) interface that transfers both data and supply voltage. This interface is widely used and is especially appropriate for the deployment near street installation, combining many different devices to one PoE source.
