RSU-201E

V2X Roadside Unit, ETSI TC-ITS protocol stack

An extended temperature V2X roadside unit with cellular capability, RSU-201E provides preloaded ETSI TC-ITS stack running on Linux OS. The SDK enables direct Linux version V2X application software porting on C/C++ user space code to meet "Tomorrow's Smart City, Today."


Tomorrow’s V2X RSU, Today

Integration of module-structured i.MX6/Cellular/GNSS main board (HVP-201), DSRC sub-system (VTX-201), and ETSI TC-ITS stack (VPS-201E) in an IP67 enclosure to directly port V2X applications on Linux® and explore V2X sensor fusion feasibility.
