Repeater
Repeater is a physical layer networking devices that amplifies and regenerates an incoming analogue/ digital signal before transmitting. The repeater simply works as a relay here and extends the coverage area.
Why it is required
Signals ideally loss or get attenuated during the transmission. A repeater reconstructs or regenerates the signal and transmits ahead. Thus it is also known as signal boosters.
When the signal communicated in a channel, it gets attenuated depending upon the nature of the channel which seems a limitation of the LAN or cellular coverage. Repeaters installed in specific intervals can help in solving the problem. It restores the signal shape.
The best use of repeater is while it connects two LANs and creates a large LAN network. Multiple LAN can connect to make a single LAN.
There are different types of repeater available such as
- Digital Repeater
- Analogue Repeater
- Wired Repeater
- Wireless Repeater
Advantages
- They are simple to install and does not impact on network performance.
- They are cost effective
- It provides stability of the signals while eliminating the distance
- They can support dynamic networking
- They support all type of signals such as digital, analogue, electrical, light based.
Demerit
- It cannot be managed.
- It cannot recognize packets, noises for any filtration purpose.
