In telecommunications, relay systems are used to extend the range and improve the reliability of signals across vast distances. Relay stations in telecommunication networks act as intermediaries, receiving signals and retransmitting them to far-off destinations. This is especially important in satellite communication systems, where signals sent from Earth need to be bounced off satellites before reaching remote locations. Similarly, relay stations are integral to mobile networks, including 4G and 5G systems, as they ensure robust coverage in urban and rural areas alike. Additionally, data relays in packet-switched networks, such as the internet, allow for efficient and reliable data routing between multiple nodes, ensuring seamless connectivity.
