WSA - LTE-V2X WSMP
Description:
This solution is used within Canada and the U.S.. It combines standards associated with WSA with those for V-X: LTE-V2X WSMP. The WSA standards include standards required to advertise ITS services to short-range wireless devices. 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: 13
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 | Overlap of standards (Minor) | 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. However, as this information transfer is infrastructure-based, agencies can deploy a solution throughout their jurisdiction with minimal downside and can use gateways to connect to other technologies. |
| True | Low | Time synchronization | Performance / Applicability Gap | The standard requires a highly accurate time shared between participants. |
| True | Medium | Uncertainty about trust revocation mechanism | Security Gap | The mechanisms used to prevent bad actors from sending authorized messages is unproven. |
| True | High | Draft not available (Critical) | Standardization Gap | The standards development organization has established a work item for the subject standard but a draft is not available for this critical feature to enable the interface. The draft may be missing due to the work item being new or simply a lack of activity on the work item. |
