toistinlaitteet
Toistinlaitteet, known in English as repeaters, are electronic devices used in telecommunications and computer networking to regenerate and retransmit a signal. They are essential components for extending the range of signal transmission over long distances. When a signal travels through a medium like a cable or the air, it gradually loses strength, a phenomenon called attenuation. A repeater receives this weakened signal, amplifies it, and then retransmits it, effectively boosting its power and allowing it to travel further without significant degradation.
In networking, repeaters operate at the physical layer (Layer 1) of the OSI model. They do not
