At its core, Relay technology refers to a method of transferring signals, data, or information between two points via intermediate devices, called relays. These relays are responsible for receiving and forwarding the signals, often with amplification, modulation, or filtering to maintain the quality and strength of the transmission over long distances. Relay systems are vital in extending the range and reliability of communication networks, especially when direct transmission between the sender and receiver is not possible due to distance, signal degradation, or obstacles.
