Roadside units (RSUs), which are important components of ETC devices, play a crucial role in ensuring the proper operation and performance of the entire ETC device. The roadside unit is arranged right above an expressway or an urban road, has the height of 3.m5.5m, and realizes the non-stop toll collection of vehicles running on the expressway or the urban road by communicating with an on-board unit (OBU) on the inner side of a front windshield of the vehicle running on the expressway or the urban road, so that the vehicles are allowed to pass at high speed, and the traffic capacity of the expressway or the urban road is greatly improved.

Obviously, the roadside unit of the ETC device of the Roadside (RFID) needs to arrange a large number of inductance lines densely on the road, so that the construction is complicated, the communication reliability is reduced, and other reasons are brought, and the conventional roadside unit of the ETC device can not meet the requirements of the user vehicle on the passing speed (up to 100km/h), the communication quality (the transaction success rate is more than 99%) and the communication effectiveness (the transmission of data with large information quantity such as pictures and the like can be realized).
