Datasheet

Description

RSU-352 is the most advanced V2X roadside unit featuring a global V2X solution; the hardware supports either C-V2X or DSRC-V2X communication standards with appropriate V2X stack embedded, reducing the cost and complexity for cooperative intelligent transportation systems (C-ITS) deployments.

The rugged waterproof IP67 aluminum enclosure protects against water and dust ingress. A GORE® vent balances the air pressure to increase the RSU service life. Additionally, surge protectors are affixed to both the antenna and PoE ports, increasing the level of protection.

With embedded ITS-G5 or IEEE 1609 V2X stack for either DSRC-V2X or C-V2X (PC5), users can directly use the RSU for secondary software development, without the hassle of handling the V2X protocol details from scratch.
