RSU, abbreviated as Road Side Unit, is a device installed on the roadside in the ETC system that uses DSRC (Dedicated Short Range Communication) technology to communicate with the On Board Unit (OBU), achieving vehicle identification and electronic deduction of points. In the management of highways and parking lots, install RSUs on the roadside and establish unmanned express lanes. The design of RSU follows the national standard GB20851 and the communication frequency is 5.8GHz. The RSU is composed of a high gain directional beam controlled read write antenna and an RF controller. The high gain directional beam controlled read write antenna is a microwave transceiver module responsible for sending/receiving signals and data, modulation/demodulation, encoding/decoding, encryption/decryption; The RF controller is a module that controls the transmission and reception of data, as well as the processing of sending and receiving information to the upper computer
