摘要

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, it 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 femtocells, traffic shaping and heterogeneous or vertical roaming across different radio access technologies may improve the performance of off-board or cloud-based vehicular applications Furthermore, the paper suggests that over the long term, vehicles will serve as wireless gateways that manage and collect data a number of devices or sensors deployed in vehicles and highway infrastructure, utilizing 4G cellular as the last-mile wide-area connection to the cloud. 4G will likely manage devices and sensors that utilize a variety of short range radio access technologies such as Wi-Fi that provide the last yard connection.
