Uudelleenlähettimet
Uudelleenlähettimet, often referred to as repeaters in English, are electronic devices used to regenerate and retransmit a signal. Their primary function is to extend the range of a signal, whether it be radio waves, data signals in a network, or other forms of communication. By receiving a weak or degraded signal, a repeater amplifies and cleans it up before sending it onward. This process allows signals to travel much further than they would be able to on their own.
In telecommunications, repeaters are crucial for long-distance communication systems. For instance, in early telegraphy, repeaters were
In computer networking, repeaters operate at the physical layer of the OSI model. They are simple devices
