TMC - Wide Area Broadcast
Description:
This solution is used within Australia, 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.Relevant Regions:
- Australia
- European Union
- United States
Comm Profile: C-X: Wide Area Broadcast
Comm Class: WAN - Wide Area Network

Solution Issues Severity: 4
The severity issue score calculation only includes issues associated with standards that are included by default.
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 | Medium | Security inadequate | Security Gap | The solution does not provide adequate communications security for the information triple, which potentially jeopardizes C-ITS operations. |
