Microwave Link

A microwave link is the channel that is used to transmit the information between stations.

The radio frequency signal whose frequency ranges from 300 MHz to 300 GHz is usually called to be the radio signal. The line that transmits the radio signal is the microwave link.

NOTE:

Figure 1 shows the classification of radio stations. The communication channel between two radio stations is the microwave link. The radio stations are classified by function as follows:

Figure 1 Classification of Radio Stations

• Terminal station: A station located at either end of the link or at the endpoint of a tributary link.
• Relay station: A station located in the middle of the link without adding or dropping services.
• Pivotal station: A station located in the backbone link to communicate with other stations in various directions.
• Add/drop station: A station located in the middle of the link to add/drop tributaries and realize the communication in two directions of the backbone link.
