So, imagine a redstone repeater…

Network repeaters work on the Physical layer and boost signals and reduce noise, unlike an amplifier, which increases both noise and signal.

They're a simple way to extend network range and ensure good signal quality.

1. Usage scenarios
   • wired repeaters;
   • wireless repeaters;
   • optical repeaters.
2. Data handling
   • analog repeaters;
   • digital repeaters.
3. LAN domain location
   • local repeaters;
   • remote repeaters.

==== Shortcomings ====

1. Lack of data filtering or segmentation.
2. The number of repeaters must be limited.
