US: SAE Other J2735 - Local Unicast Wireless (1609.2)

Description:

This solution is used within the U.S.. It combines standards associated with US: SAE Other J2735 with those for V-X: Local Unicast Wireless (1609.2). 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: Local Unicast Wireless (1609.2) standards include lower-layer standards that support local-area unicast wireless solutions applicable to North America, such as WAVE DSRC, LTE-V2X, LTE, Wi-Fi, etc.

Comm Profile: V-X: Local Unicast Wireless (1609.2)

Standards in Profile:

Level	Doc #	Standard	Description
Access		Bundle: Local Unicast Wireless SubNet (US)	A set of alternative standards that can be used to wirelessly unicast information device-to-device in a range of a few hundred meters without requiring the aid of a 3rd entity base station. This includes technologies such as WAVE, C-V2X, and the device-to-device mode of 3GPP 4G and 5G. NOTE: WAVE and C-V2X are both intended for the same 5.9 GHz spectrum, which is currently assigned to WAVE within the US; however, as of late 2019, the FCC is considering a proposal to reassign portions of this spectrum.
Security		Bundle: IEEE 1609.2	A bundle of standards that groups a set of IEEE security standards together for easy reference.
TransNet	IEEE 1609.3	IEEE 1609.3 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.

Data Profile: US: SAE Other J2735

Standards in Profile:

Level	Doc #	Standard	Description
Facilities	SAE J2735	SAE J2735 DSRC Message Set	This standard defines the data and messages for use in DSRC (i.e., V2V, V2I, and V2D) applications. The SAE J2945 series defines additional requirements on how to use these messages.
ITS Application Entity	SAE J2735	SAE J2735 DSRC Message Set	This standard defines the data and messages for use in DSRC (i.e., V2V, V2I, and V2D) applications. The SAE J2945 series defines additional requirements on how to use these messages.

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.
