Here you go :
In a wireless communications system, a repeater consists of a radio receiver, an amplifier, a transmitter, an isolator, and two antennas.
The transmitter produces a signal on a frequency that differs from the received signal. This so-called frequency offset is necessary to prevent the strong transmitted signal from disabling the receiver.
The isolator provides additional protection in this respect. A repeater, when strategically located on top of a high building or a mountain, can greatly enhance the performance of a wireless network by allowing communications over distances much greater than would be possible without it.

Repeaters are used to re-generate the signals over a network cable. The purpose for this is so that the signal can be reaced from the sender to the receiver over the network.

They basically just extend the wireless signal.
