Meaning – The term repeater, refers to a node of a local area network; a device that regenerates signals in order to extend the range of transmission between data stations or to interconnect two branches.
It receives a signal on a specific frequency, then amplifies and rebroadcasts it. By amplifying the signal, a repeater increases the transmission range of the original signal.
Repeaters have many applications, but in computing, they are most commonly used in wireless networks.
While repeaters all serve the same purpose, they come in many forms. Some wireless devices, often called “range extenders” are designed to be used specifically as repeaters.
Example of usage – “A Wi-Fi network in a large home may benefit from using one or more repeaters to relay the signal to different areas of the house. Homes that have brick walls or cement floors may also benefit from having a repeater relay the signal around the obstacle.”
