RSU-201U

V2X Roadside Unit, IEEE 1609.x protocol stack

An extended temperature V2X roadside unit with cellular capability, RSU-201U provides preloaded IEEE 1609.2/3/4 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.MX 6/Cellular/GNSS main board (HVP-201), DSRC sub-system (VTX-201), and IEEE 1609.x stack (VPS-201U) in an IP67 enclosure to directly port V2X applications on Linux® and explore V2X sensor fusion feasibility.
