(None-Data) - Wide Area Broadcast
Description
This solution is used within Australia, the E.U. and the U.S.. It combines standards associated with (None–Data) with those for C–X: Wide Area Broadcast. The (None–Data) standards include an unspecified set of standards at the upper layers. The C–X: Wide Area Broadcast standards include lower–layer standards that support one entity broadcasting information to all wireless devices over an area that covers at least a metropolitan area without any expectation of acknowledgement or response; security is provided by the upper–layers.

Readiness Description
Many serious issues. This category includes solutions that have not been standardized, or do not have a basic level of interoperability or security. Consider selecting a different communications solution or if this is not possible (eg. a pilot of a new application that has not been standardized), take additional measures to provide an acceptable level of security or interoperability.
Issues
| Issue | Severity | Description | Associated Standard | Associated Triple |
|---|
| Data profile not defined | Ultra | Performance, functionality, and the upper–layers of the OSI stack have not been defined for this information flow. | (None) | (All) |
|---|
| Ubiquitous broadcast technology | Low | With the continual enhancement of broadcast technologies and a mixture of free and subscriber–based systems, it is difficult to identify any single technology that can be used to reliably reach the bulk of drivers in a timely manner. | (None) | (All) |
