US: SAE Other J2735 - WAVE TCP
Description
This solution is used within the U.S.. It combines standards associated with US: SAE Other J2735 with those for V–X: WAVE TCP. The US: SAE Other J2735 standards include upper–layer standards required to implement V2X information flows that do not yet have fully specified functionality and performance charcateristics. The V–X: WAVE TCP standards include lower–layer standards that support connection–oriented vehicle–to–any communications within ~300m using the Transmission Control Protocol (TCP) over Internet Protocol version 6 (IPv6) over IEEE WAVE in the 5.9GHz spectrum.

| TransNet | 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: Moderate–Low
Readiness Description
Multiple significant and minor issues. For existing deployments, the chosen solution is likely deficient in security or management capabilities, and the issues should be reviewed and upgrades developed as needed. Some solutions in this category may also be becoming obsolete from an interoperability perspective and if this is the case, then upgrades should be planned as soon as possible. For new deployments, the solution may be viable for pilots when applied to the triples it supports; such pilot deployments should consider a path to addressing these issues as a part of their design activities. The solution does not provide sufficient interoperability, management, and security to enable proper, full–scale deployment without additional work.
