CHARACTERISTIC OFREPEATER

REPEATERRepeater are the simplest type of connectivity devices that regenerate a digital signal

Repeater operate in the Physical layer of the OSI Model

A repeater contains one input port and one output port, so it is capable of receiving and repeating only the data stream

Repeaters are suited only to bus topology networks

Functions of RepeaterRegenerates & replicate signals

Extend the LAN segments

Moves packets from one LAN transmission medium

Connect buildings togetherAnalog frequently amplify signals

Digital can additionally reconstruct signals

Relay messages between subnetwork

Provide simple way to solve the Ethernet distance limitations

AdvantagesWireless Repeater or range extender is a device that help computer maintain stronger wireless signal by taking in signal from router and remitting them.

Detect and rebroadcast the wireless signal

Effectively halves the bandwidthDisadvantageWireless router can also served as repeater

Real world performance metrics show that router has a longer foot-range compare to repeater
