juurdepääsuvõrk

Juurdepääsuvõrk, also known as the access network, refers to the part of a telecommunications network that connects end-users to their service provider's wider network. It is the final link in the chain that delivers services such as voice, data, and video to homes and businesses. In simpler terms, it's the infrastructure that brings the internet and phone lines from the street cabinet or exchange to your doorstep.

Historically, the juurdepääsuvõrk was primarily based on copper wire telephone lines, supporting voice communication and dial-up internet. However, with the increasing demand for high-speed data, significant advancements have been made. Fiber optic cables are now a major component of modern access networks, offering much higher bandwidth and faster speeds compared to copper. Technologies like DSL (Digital Subscriber Line) utilize existing copper infrastructure to provide broadband internet, while newer fiber-to-the-home (FTTH) deployments directly connect fiber optic cables to individual residences.

Wireless technologies also play a crucial role in the juurdepääsuvõrk, especially in areas where laying physical cables is difficult or uneconomical. Mobile networks (like 4G and 5G) provide wireless access to the internet for mobile devices, and fixed wireless access (FWA) can offer broadband services to homes and businesses without physical cables. The development and expansion of the juurdepääsuvõrk are critical for digital inclusion, economic growth, and the adoption of new technologies and services.
