US: SAE Safety Awareness Messages - WAVE WSMP

Description

This solution is used within the U.S.. It combines standards associated with US: SAE Safety Awareness Messages with those for V–X: WAVE WSMP. The US: SAE Safety Awareness Messages standards include upper–layer standards required to implement V2V safety situation awareness information flows. The V–X: WAVE WSMP standards include lower–layer standards that support connectionless, near constant, ultra–low latency vehicle–to–any communications within ~300m using the WAVE Short Messaging Protocol (WSMP) over IEEE WAVE in the 5.9GHz spectrum. The broadcast mode is interoperable with M5 FNTP.

Readiness: High–Moderate

Readiness Description

One significant or possibly a couple minor issues. For existing deployments, the chosen solution likely has identified security or management issues not addressed by the communications solution. Deployers should consider additional security measures, such as communications link and physical security as part of these solutions. They should also review the management issues to see if they are relevant to their deployment and would require mitigation. For new deployments, the deployment efforts should consider a path to addressing these issues as a part of their design activities. The solution does not by itself provide a fully secure implementation without additional work.
