智能交通系统的无线通信技术探讨

Discussion on the Wireless Communication Technology in Intelligent Transportation System

以智能交通系统的基础概念和基本架构展开介绍,分析智能交通系统在每种场景中的无线通信系统的时延、速率、覆盖等指标,并对现有主流无线接入系统GSM、3G(FDD、TDD、cdma2000)、LTE(FDD、TDD)、WiMAX、DSRC、McWiLL的对应指标进行研究,结合智能交通系统的无线需求和典型无线接入系统的特点,给出智能交通系统的无线接入系统应用建议和策略。

This article introduces the definition and architecture of intelligent Transportation System at first. Then it discusses the time delay, speed, data throughput and coverage of each scenario for wireless commication of ITS. Based on the analysis of charac-teristics of GSM, 3G, LTE, WiMAX, DSRC and McWiLL technology, it gives suggestion and applica-tion strategy of wireless communication for ITS.
