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.
Includes Standards
| Level | DocNum | FullName | Description |
|---|
| Mgmt | IEEE 1609.3 | IEEE Standard for Wireless Access in Vehicular Environments (WAVE) – Networking Services | This standard defines the network and transport layer options for the WAVE environment. The standard defines three options: a bandwidth efficient single–hop solution known as WSMP, UDP/IP, and TCP/IP. It has been harmonized with ISO FNTP and FSAP – a common message format specified in ISO 16460. |

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.
