Why 802.11p beats LTE and 5G for V2x.pdf

Abstract
V2x communication, which involves vehicles exchanging data with each other and the infrastructure, has
proven to improve traffic safety and increase the efficiency of transportation systems. Direct Short
Range Communication (DSRC), which is based on IEEE 802.11p, has been the subject of extensive
standardization, product development and field trials by all stakeholders, proving its benefit for V2x.
Unlike cellular technologies, DSRC is ready for V2x deployment today, and addresses the most
challenging V2x use-cases.

作为一款专业的汽车工程师，关于802.11p在V2x通讯方面优于LTE和5G的原因有以下几点：首先，802.11p拥有专门针对车联网的快速通信标准；其次，在延迟与稳定性方面，它能保证高效实时的数据传输，尤其适用于高速行驶的车辆的通讯需求；再者，其在短距离通信领域拥有较高表现。因此，相较于LTE和5G，802.11p更适用于V2x场景下的通信应用。基于Direct Short Range Communication（DSRC）技术的运用确保了高效、安全的车辆与基础设施间的数据交换。
