民航的通信包括有线通信无线通信。其中有线通信包括电话通信、电报通信。而无线通信主要是地空通信,即地面管制人员与空中机组人员的通信。近几十年来,随着科学技术的突飞猛进,民航的通信取得了飞跃的发展,特别是计算机技术广泛应用于有线、无线通信的各个领域。电话机已广泛采用程控交换技术,自动转接代替了人工操作。电报的通信从人工莫尔斯码收发到电传机,发展到现在的自动转报系统。以前需要手工完成的大量工作已由计算机代替,电报的传递更准确、更迅速、更方便。无线通信从过去到现在已经历了近百年,其技术也发生了很大的变化,从模拟到数字,从点对点通信网进入地域通信网;从无干扰措 Civil aviation communications include wired communications wireless communications. The wired communication includes telephone communication and telegraphy communication. The wireless communications are mainly ground-based communications, that is, ground control personnel and air crew communications. In recent decades, with the rapid development of science and technology, civil aviation has made leaps and bounds in communications. In particular, computer technology is widely used in various fields of wired and wireless communications. Telephone has been widely used program-controlled switching technology, automatic transfer instead of manual operation. Telegraph communications from the manual Morse code transceiver to the teletype machine, the development of the current automatic reporting system. Much of the work previously required to be done by hand has been replaced by computers, where the transmission of telegrams is more accurate, faster and easier. Wireless communication has experienced nearly a hundred years from the past to the present, and its technology has undergone great changes. From analog to digital, it enters the area network from the point-to-point communication network. From the non-interference
