This solution is used within the U.S.. It combines standards associated with US: SAE Safety Awareness Messages with those for V-X: WAVE WSMP. The US: SAE Safety Awareness Messages standards include upper-layer standards required to implement V2V safety situation awareness 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 the 5.9GHz spectrum. The broadcast mode is interoperable with M5 FNTP.
