The Function of a Repeater in Networking 

In this article we have explained and answered frequently asked questions like, Types of repeater in networking, Features of repeater in networking, and How repeater works in network, a repeater is a network device that returns a received signal faster and to an extended geographic or topological network boundary than the original signal could.

A repeater is implemented in a computer network to extend the coverage area of ​​a network, propagate a weak or damaged signal, or serve remote nodes. The repeater extends the received signal to a higher frequency range, making it reusable, scalable, and usable.

Repeaters have been introduced into cable data communications networks as a result of the restriction on signal propagation over longer distances and are now more commonly installed in wireless networks to expand cell size.

Any computer or data communication network running has a certain limit in which it can serve the connected and authorized hosts or nodes. This is the planned network bandwidth, but sometimes the network needs to expand its routing domain to accommodate new/existing hosts or to increase the level of service in a particular topology domain. In such a scenario, the network uses a repeater service, which amplifies the received signal to an ideal or near-ideal power to allow the destination/receiving node to receive data.


Installation of a repeater is paramount, especially in areas where signal attenuation and loss is very much critical. Repeaters are more often than perceived as illogical devices as they pass any signal, regardless of size, type, etcetera. The repeater supports both analog and digital signals and is able to reproduce both electrical and optical signals.

The function of a Repeater in Networking

A repeater is used to connect two signals from a local area network (LAN). It is impossible to connect all devices with a cable thus, repeaters allow you to extend coverage and access a wider network with the same signal strength. Repeaters are used to extend the transmission so that the signal can travel long distances. This ensures a long signal coverage and makes it accessible to the destination, which is not possible with the router itself.

In a wireless communication system, the repeater receives the current signal from the access point

and sends it back to establish a second network. A repeater is a dual-port device and it is often used in homes and small offices to use the signal on a larger scale. It boosts the signal and extends the Wi-Fi range.

The repeater has always been considered an illogical device as it will transmit every time regardless of the part. A repeater supports both analog and digital signals and removes unwanted noise from the signal so that the signal is noise-free. Digital repeaters are capable of reproducing signals distorted by transmission as well as reproducing the interrupted signal.

Repeaters are not difficult to install and they are inexpensive and do not require a complicated installation process. Some of the drawbacks are; It only connects to the network as it is, does not differentiate sound, does not reduce traffic or congestion, and the router or network may have some restrictions regarding the number of repeaters that can be installed on a network.
