Ligipääsuvõrku

Ligipääsuvõrk, also known as the access network, refers to the part of a telecommunications network that connects end-users to the wider network infrastructure. In essence, it is the final link that brings services like internet, telephone, and television to homes and businesses. This network typically comprises a variety of technologies, ranging from traditional copper telephone lines to more modern fiber optic cables and wireless solutions such as 4G and 5G. The primary function of the ligipääsuvõrk is to provide the necessary bandwidth and connectivity for individual subscribers to access the services offered by their internet service provider or telecommunications company.

The evolution of the ligipääsuvõrk has been driven by the increasing demand for higher data speeds and greater capacity. Early access networks were primarily designed for voice communication and had limited data transmission capabilities. However, with the advent of the internet and the proliferation of data-intensive applications, there has been a significant shift towards broadband technologies. Fiber-to-the-home (FTTH) is increasingly becoming the preferred solution for new deployments due to its ability to deliver exceptionally high speeds and its future-proofing potential. Conversely, hybrid fiber-coaxial (HFC) networks, commonly used for cable television, also provide broadband internet access. Wireless access technologies, while not always a permanent replacement for wired connections, play a crucial role in providing flexibility and reaching areas where wired infrastructure might be difficult or expensive to deploy. The performance and capabilities of the ligipääsuvõrk are critical factors in the overall quality of service experienced by end-users.
