Definition ∞ Physical layer optimization involves enhancements made to the fundamental hardware and connectivity components of a network to improve performance, reliability, and data transmission efficiency. This process focuses on refining the physical infrastructure elements that carry data, such as cables, transceivers, and routing equipment. It aims to maximize the underlying network’s capabilities.
Context ∞ In the context of decentralized physical networks (DePINs), physical layer optimization is crucial for delivering high-quality services like internet access or data storage. Improvements at this foundational level directly impact the speed, stability, and cost-effectiveness of the decentralized service. News reports on DePINs often detail advancements in their physical infrastructure to attract users and resource providers.
