近年来,由于无线电通信事业的兴旺发展,频率分配非常紧张,有效利用频谱的呼声越来越高。因此,也促进了世界各国对各种基本技术进行研究和利用。其中之一是有关国家的主管部门为满足用户对通信需求量大,要求设备简单和操作容易的特点,已组织开发了一种称为“个人无线电台”的通信方式。目前美国和日本等国均已投入使用,本文就日本的个人无线电台的情况加以介绍。
In recent years, due to the rapid development of radiocommunication services, the frequency allocation has been very tense, and the voice of effectively utilizing the spectrum has become louder and louder. Therefore, all countries in the world have also promoted the research and utilization of various basic technologies. One of these is that the competent national authorities of the countries concerned have developed a means of communication called “personal radio” to meet the demands of users for their high demand for communications, their simplicity of equipment and ease of operation. At present, the United States and Japan have all put into use. This article introduces the situation of personal radio stations in Japan.
