This solution is used within the U.S.. It combines standards associated with US: ATIS with those for I–M: Secure Wireless Internet (ITS). The US: ATIS standards include upper–layer standards required to implement traveler information communications. The I–M: Secure Wireless Internet (ITS) standards include lower–layer standards that support secure communications between two entities, either or both of which may be mobile devices, but they must be stationary or only moving within wireless range of a single wireless access point (e.g., a parked car). Security is based on X.509 or IEEE 1609.2 certificates. A non–mobile (if any) endpoint may connect to the service provider using any Internet connection method.

One serious or several significant issues. This category often includes proprietary or partial solutions. The communications solution may fail to provide even a base level of interoperability and security. Consider alternative solutions, or define specific revisions or upgrades that would provide a level of interoperability or security that are needed for the deployment.
