What is the function of a repeater?

A repeater is a connecting device above the physical layer of the network.

It is suitable for the interconnection of two identical types of networks. Its main function is to expand the network transmission distance by retransmitting or forwarding data signals.

A repeater is a network device that regenerates and restores signals. A physical layer device of the OSI model.

Simply put, repeaters are used to amplify signals in network cables. The theoretically stable maximum transmission distance of general Category 5 network cables is 90 meters, but in practice, the average brand only has 70~80 meters.

Packets will be lost.

At this time, if we still have to use ordinary Category 5 twisted pair for transmission, we need to place a repeater at a position of 80 meters, so that the line can work stably within a length of 160 meters.
