RSU-101U

V2X Enabling Roadside Unit, IEEE 1609.x protocol stack

An extended temperature V2X enabling roadside unit with preloaded IEEE 1609.2/3/4 stack running on ThreadX in an IP67 enclosure, RSU-101U and SDK enable direct SPaT/MAP and V2X application deployment for communication between vehicles and traffic controllers in co-operative ITS applications.


Preloaded 1609.x stack and the SDK to Enable Traffic Priority Systems

Connects RSU-101U to traffic control system through Ethernet to enable the next generation real-time traffic priority systems for certain vehicle types and minimize the impact of non-prioritized to increase road efficiency.
