reläasemien
Reläasemien, often translated as relay stations or repeater stations, are crucial components in the infrastructure of telecommunications and power transmission. In telecommunications, a relay station is a facility that receives a signal, regenerates it, and then retransmits it to its destination. This process is vital for extending the range of signals over long distances, especially in older analog systems or in areas where direct transmission is not feasible due to terrain or other obstructions. They were particularly important in the development of telegraph and telephone networks, acting as intermediate points to boost signal strength and clarity. In modern digital networks, while the concept of regeneration remains, dedicated physical relay stations are less common, with the function often integrated into more sophisticated network equipment.
In the context of power transmission, relay stations, more commonly referred to as substations or switching
