4G for Vehicle Safety Communications

This chapter first provides a brief overview of the leading fourth-generation (4G) cellular technology — the Long-Term Evolution (LTE). It then uses examples to illustrate the technical feasibility and potential issues to be addressed when using LTE to support vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) safety communications. The leading 4G cellular network standard is the LTE developed by the Third-Generation Partnership Project (3GPP). LTE offers significantly higher capacities and lower delays than third-generation (3G) cellular networks. As LTE deployment progresses worldwide, 3GPP has been developing LTE Advanced. Using cellular networks for supporting the communications of a large number of vehicles can have a profound impact on the cellular networks and requires an in-depth examination of several fundamental issues. Third-generation (3G) cellular networks support cell broadcast service (CBS) that broadcasts low-rate text messages to all receivers inside one cellular cell.
