US: SAE Weather Info - LTE-V2X WSMP
Description:
This solution is used within Canada and the U.S.. It combines standards associated with US: SAE Weather Info with those for V-X: LTE-V2X WSMP. The US: SAE Weather Info standards include upper-layer standards required to implement V2X weather information flows. The V-X: LTE-V2X WSMP standards include lower-layer standards that support connectionless, near constant, ultra-low latency vehicle-to-any communications using the WAVE Short Messaging Protocol (WSMP) over 3GPP C-V2X in the 5.9GHz spectrum.Relevant Regions:
- Canada
- United States
Comm Profile: V-X: LTE-V2X WSMP
Comm Class: LAN - Local Area Network

Solution Issues Severity: 10
The severity issue score calculation only includes issues associated with standards that are included by default.
Solution Issues:
| Default | Severity | Name | Type | Description |
|---|---|---|---|---|
| True | Low | Data not defined in standard format | ITS Info Gap | The definition of data concepts should conform to ISO 14817-1 to promote reuse among ITS. |
| 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 | Regulatory Permission Needed | Standardization Gap | Deployment of this standard requires regulatory approval, which is currently subject to significant delays. |
| True | Medium | Uncertainty about trust revocation mechanism | Security Gap | The mechanisms used to prevent bad actors from sending authorized messages is unproven. |
