The purpose of repeater is to extend the LAN segment beyond its physical limits.


Repeaters are used to connect two physically close building together.

Repeaters operate at the  "Physical layer" of OSI model.

Repeaters can join two different physical physical media  but they must use the same access method.

Repeaters handle only the electrical and physical characteristics of the signal.

Repeaters works only the same type of physical layer as Ethernet-to-Ethernet.
