EU: CA Service - BTP/GeoNetworking/G5 (13)
US: SAE LTE-V2X BSM - LTE-V2X WSMP (16)
US: SAE Basic Safety Messages - WAVE WSMP (18)

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

US: SAE Basic Safety Messages - WAVE WSMP

Solution Description

This solution is used within the U.S.. It combines standards associated with US: SAE Basic Safety Messages with those for V-X: WAVE WSMP. The US: SAE Basic Safety Messages standards include upper-layer standards required to implement V2V safety information flows. 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.
