随着我国国民经济的飞跃发展,陆上移动无线电通信事业必将迅速发展起来;工矿企业和城市的甚高频与超高频无线电车辆调度就是一个很现实的例子。由于使用无线电台数量的不断增加和这种通信业务范围的不断扩大,这就给无线电频率管理工作提出一个问题:即移动无线电通信中频率的合理使用问题。本文对此就以下三种情况作一个一般性的介绍。一、大面积连续复盖各基地台的移动通信; 二、基地台装备无线电交换设备的意义; 三、城市汽车无线电调度通信网。
With the rapid development of our national economy, land mobile radiocommunications will surely develop rapidly. The scheduling of VHF and UHF radio vehicles for industrial and mining enterprises and cities is a very realistic example. As a result of the increasing use of radio stations and the expanding range of such communications services, this raises a problem for radio frequency management: the question of the fair use of frequencies in mobile radiocommunication. This article gives a general introduction to the following three situations. First, a large area of continuous coverage of the base station mobile communications; Second, the base station equipped with the meaning of the exchange of radio equipment; Third, the urban car radio dispatching communication network.
