  • repeaters work by amplifying the received signal then rebroadcasts it to another area.
  • by amplifying the signal, a repeater increases the transmission range of the original signal.

  • WiFi Repeater - is used to extend the coverage area of your Wi-Fi network.
  • Network Repeater - this is that whatever it
    receives it transmits to the
    other LAN segment. This
    does not understand the
    frame format and also
    physical addresses. In other
    words, it is a transparent
    device. Therefore, multiple
    LANs connected by
    repeaters may be
    considered as a single LAN.
  • Telephone Repeater - is used to amplify signals to support and carry long distance calls.
  • Submarine Cable Repeater 
  • Radio Repeater - this is used to extend the coverage of a radio signal.

  • It amplifies the signal.
  • It does not affect the performance of the network when it’s performing its task on the signal.
  •  Repeaters can be used in different mediums for reception and transmission.
  • It does not increase or decrease the network traffic.

  • It is not possible to connect different network architectures using repeater. For this router or gateway is needed.
  • The number of repeaters to be used are limited between two ends. More repeaters create noise on the wire which results into packet collisions or problems in the packet detection.
  • Repeaters do not perform filtering of the data.

  • is a kind of networking device that interconnects two or more networks together by dividing LAN into different segments.
  • commonly has a single input and single output port, thus making it a 2 port device.
  • can be wired and wireless
  • can also work by
    connecting LANs that
    work on the same protocol.
