第一条微波电话通信应用试验电路出现在50年前,即1931年3月31日,它架设在英国的多维尔(Dover)和加来斯(Calais)之间.这次试验成功表明,自1000至10000兆赫频段在提供宽频带通信信道方面具有相当大的潜力.由于第一条试验电路的成功,一个由微波接力线路组成的广阔的通信网已在联合王国建成,它具有190个中继站和终端站,总数约3.5亿话路公里.这种通信网提供了一种传输方法,它与同轴电缆系统根本不同但互为补充,从而保证整个通信网的基本安全.而且无线电接力线路对于连接干线传输网到那些遥远的或地理上电缆难以沟通的地方具有特殊的价值.例如,苏格兰的高地和岛屿,以及远离本土的北海油田和气井.
The first microwave telephony application trial circuit appeared 50 years ago, on March 31, 1931, between Dover and Calais in the UK This trial has shown that since The band 1000 to 10000 MHz has considerable potential for providing broadband communication channels.As a result of the success of the first pilot circuit, a vast telecommunications network of microwave relay lines was completed in the United Kingdom with 190 relay stations and Terminal station, a total of about 350 million road kilometer.This communication network provides a transmission method, which is fundamentally different from the coaxial cable system but complement each other, so as to ensure the basic safety of the entire communication network.And the radio relay line connection Trunk transmission networks are of particular value in places that are remote or where the geographical cables are difficult to communicate with, for example, the highlands and islands of Scotland, and the North Sea fields and gas wells far from home.
