Repeater

• In telecommunication networks, a repeater is a device that receives a signal amplifies it and then retransmits it along the next leg of the network. It is used to ensure signal strength and allow the high quality necessary for broadband.
  
  A series of repeaters make it possible to boost a signal over a much greater distance than would otherwise be possible.

Repeaters are also used to interconnect segments in a local area network (LAN) for example, to boost the signal to and from a wireless modem to ensure high quality signal.
