近年来，人们对ITS（智能交通系统）进行了大量的研究。实现ITS网络的主要规范是使用5.8GHz频段的RC-005。然而，由于无线电的特性，如果某些东西干扰通信设备之间的视线（LOS），则很难连接。本文提出了一种基于时间备份和频率备份的通信系统，以提高通信的稳定性和覆盖范围。我们实现了原型系统，并进行了一些实验使用它们。结果表明，时间备份和频率备份在数据到达率和通信稳定性方面是有效的。我们得出结论的情况下，非视距（NLOS）通信，时间备份和频率备份是有效的。
Recently, there have been large numbers of research related to ITS (Intelligent Transport System). The major specification to realize ITS network is RC-005 using band frequency 5.8GHz. However it is difficult to connect if something disturbs Line-of-Sight (LOS) between communication devices due to characteristic of radio. In this paper, we propose a communication system based on approaches of temporal backup and frequency backup to increase communication stability and to cover wider area. We implement the prototype system and conduct some experiment using them. The result shows that temporal backup and frequency backup are effective in terms of data arrival rate and stable communication. We conclude in case of Non Line-of-Sight (NLOS) communication, temporal backup and frequency backup are efficient.
