TMC - Wide Area Broadcast

Description:

This solution is used within Australia, Canada, the E.U. and the U.S.. It combines standards associated with TMC with those for C-X: Wide Area Broadcast. The TMC standards include upper-layer standards required to support multi-modal information services to the vehicle. 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.

Solution Issues Severity: 9

Solution Issues:

Default	Severity	Name	Type	Description
True	Low	Ubiquitous broadcast technology	SubNet Gap	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.
True	High	Out of date (high)	Standardization Gap	The standard includes normative references to other standards that have been subject to significant changes that can impact interoperability of systems and the industry has not specified if and how these updates should be implemented for deployments of this standard.
