Repeaters extend the communication distance. The maximum number of nodes has been increased. Each network segment can use different communication rates. Improved reliability. When the network fails, it generally only affects individual network segments. The Internet performance is improved.

The main advantages of repeater are simple installation, convenient use and relatively low price. It not only plays the role of network distance, but also can connect networks of different transmission media together. The repeater works at the physical layer and is completely transparent to the high-level protocol.
