WSA - WAVE WSMP
Description:
This solution is used within the U.S.. It combines standards associated with WSA with those for V-X: WAVE WSMP. The WSA standards include standards required to advertise ITS services to short-range wireless devices. 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.Relevant Regions:

Solution Issues Severity: 14
The severity issue score calculation only includes issues associated with standards that are included by default.
Solution Issues:
| Default | Severity | Name | Type | Description |
|---|---|---|---|---|
| True | Medium | Overlap of standards | Overlap | Multiple standards have been developed to address this information and it is unclear which standard should be used to address this specific information flow. |
| True | Medium | Uncertainty about trust revocation mechanism | Security Gap | The mechanisms used to prevent bad actors from sending authorized messages is unproven. |
| True | High | Regulatory Issue | Standardization Gap | Deployment of this standard is subject to regulatory approval, which is not currently expected to be granted for deployments in the near-term. |
Solution to Triples
This solution is used on the following information flow triples:
