The last mile is the final leg of the network that connects the local points of presence to individual homes, businesses, or end-user devices. This is often considered the most critical and challenging part of the network due to the varying distances, diverse user needs, and potential obstacles that can affect data delivery quality. The goal of the last mile is to provide reliable, high-speed connectivity directly to the end-users. Last mile networks can take various forms, such as DSL (Digital Subscriber Line), cable, fiber-optic, wireless (like Wi-Fi or cellular networks), and even satellite connections. The technology used depends on factors like location, available infrastructure, and the desired level of service quality.
