Application Summary AI generated
This standard specifies the physical layer parameters for dedicated short-range communication (DSRC) in electronic toll collection (ETC) systems, including frequency bands, modulation methods, and data transmission rates. It is applied in China's highway and parking lot ETC systems to ensure interoperability between on-board units (OBUs) and roadside units (RSUs) from different manufacturers. The standard defines the radio interface requirements for the 5.8 GHz frequency band used in Chinese ETC deployments.
