A repeater is a network device used to regenerate and amplify signals to extend the range of a network.
Repeater: A Layer 1 (Physical Layer) device that receives a weak or distorted signal and retransmits it at its original strength.
| Specification | Description |
|---|---|
| Layer | Operates at Layer 1 (Physical Layer) |
| Speed Support | Matches network speed: 10/100/1000 Mbps or Wi-Fi standard |
| Port Types | Ethernet (for wired repeaters) or wireless (Wi-Fi extenders) |
| Range Extension | Typically doubles the standard range of the medium |
| Power Source | Requires external power for operation |
| Form Factor | Wall plug, desktop unit, or inline network device |
A repeater is a basic but essential device in networking used to overcome distance limitations. By regenerating signals, it ensures reliable communication across extended networks.
