Relay reliability plays a pivotal role in ensuring that communication networks, particularly wireless and remote systems, operate seamlessly and efficiently. In the context of communication systems, relays act as intermediaries that forward information between two or more devices, often extending the reach and improving the coverage of the network. As such, the reliability of relays is crucial for maintaining system integrity, minimizing downtime, and ensuring the consistent delivery of data. This article explores the concept of relay reliability, its importance, the factors that influence it, and strategies for improving it in modern communication networks.
