Description: Link quality refers to the performance characteristics of a network link, which are fundamental to ensuring efficient and effective communication between devices. This quality is measured through various parameters, including latency, bandwidth, packet loss, and latency variability (jitter). A high-quality link allows for fast and reliable data transmission, which is crucial in applications that require consistent performance, such as real-time video streaming or online gaming. Link quality also influences user experience, as a poor link can result in interruptions, delays, and poor service quality. In the context of modern networks, link quality has become even more relevant with the growth of technologies like 5G, where links are expected to offer ultra-fast speeds and low latency. Additionally, in edge computing environments and wide area networks (WAN), link quality is essential for optimizing performance and efficiency of distributed applications. In summary, link quality is a critical aspect of network infrastructure that directly affects communication effectiveness and user satisfaction.
