A proposal of spot access system for millimeter-wave road-to-vehicle communication systems by means of radio-on-fiber technology

摘要

Road-to-vehicle communication system is considered as a key technology to realize Intelligent Transport systems (ITS). In this paper, a spot access system is proposed for broadband wireless package Road-to-vehicle transmission system based on radio-on-fiber (ROF) technology. The proposed system is characterized by the following: (1) Its cell is enough small not to hold more than one vehicle. (2) Each cell has no overlaps. (3) A large package is divided into several small unit packages and transferred from several cells. By using numerical evaluation, it is clarified that higher average data transmission rate can he obtained in comparison with continuity access system, which has overlapped cell structure.
