What is Repeater in Networking

A Repeater is a network device that regenerates the incoming signal gives strengthens to transmit it to the next devices which are connected without losing any actual data or the information. To know more about What is Repeater in Networking keep reading this article till the end.
It is used in the transmission system to regenerate the analog or the digital signals distorted by transmission loss. An important point needs to be noted that repeater does not amplify the signals it only regenerates the signals to transmit at the longer distance. When the signals become weak, they copy the signals which are in the bit form and regenerate it at the original strength.
It is a two-port device and it operates at the physical layer of the OSI Model.
Repeaters were introduced in wired data transmission networks due to the limitation of a signal in propagating over a longer distance and it is a common installation in wireless networks for expanding cell size.
There are several different types of repeaters some of these are:

• Telephone repeater
• Optical communications repeater
• Radio repeater

Telephone Repeater

Telephone repeaters are used to increase the range of telephone signals in telephone lines. Telephone repeater is further categorized into two types-
