利用毫米波波叚的波导管傳輸系統是中距离和远距离發送訊号的最新类型。这种傳输訊号的方法和以前的类型完全不同,它的特点是傳輸容量非常巨大,比微波接力中继线路大許多倍,而且初步研究結果指出它是非常經济的。
Waveguide transmission systems that utilize millimeter wave 是 are the newest types of signals transmitted at medium and long distances. This method of transmitting signals is completely different from the previous one. It features a very large transmission capacity and is many times larger than a microwave relay trunk line, and preliminary results indicate that it is very economical.
