1. Expanded communication distance. 2. Increases the maximum number of nodes. 3. Different communication rates can be used for each network segment. 4. Improves reliability. When a network failure occurs, it generally affects only individual network segments. 5. Performance is improved.
The main advantages of the repeater are simple installation, ease of use and relatively low price. He not only plays the role of network distance, but also connects networks of different transmission media together. The repeater works at the physical layer and is completely transparent to higher layer protocols.
