Fourth generation (4G) wireless represents an enormous opportunity in transportation. 4G will not only enable new vehicle applications, but transportation infrastructure and "right-of-way" may potentially play host to these networks
This paper examines how next generation wide-area cellular such as 4G will be able to support vehicular applications, and how transportation infrastructure may mesh with wireless networks.
Specifically, the report suggests that automotive electronics engineers will need to be cognizant of how application data is treated by 4G Long Term Evolution (LTE) networks, and how innovations such as self-organizing small-cells, “traffic shaping” and heterogeneous or “vertical roaming” across different radio access technologies may improve the performance of off-board or “cloud” -based vehicular applications
This report speculates on the future impact of a given technology to the transportation sector in general, and specifically to a future Vehicle-to-Vehicle, Vehicle-to-Device, Vehicle-to-Infrastructure (V2X) core system relying on vehicle Dedicated Short Range Communications, as contemplated in USDOT's Connected Vehicle R&D program.
This a companion report to Machine-to-Machine Communications: M2M Technology and Potential for the Transportation Sector.
