电子收费 专用短程通信 第5部分：物理层主要参数测试方法
Application Summary AI generated
This standard specifies the test methods for key physical layer parameters in dedicated short-range communication (DSRC) systems used for electronic toll collection (ETC). It is applied in the testing and validation of DSRC equipment, such as roadside units (RSUs) and onboard units (OBUs), to ensure compliance with communication performance requirements. The standard is primarily used by manufacturers, testing laboratories, and highway operators in China to verify signal characteristics, modulation accuracy, and transmission reliability in ETC systems.
