ACCESS NETWORK Meaning and
Definition
-
Access network refers to the part of a telecommunications system that connects end users or subscribers with the wider network infrastructure. It is the physical and logical infrastructure that enables users to access and utilize various services, applications, and resources provided by a service provider or network operator.
In the context of telecommunications, an access network can be described as the last mile connection between the user premises and the service provider's central network. It is responsible for delivering data, voice, and video signals from the user's location to the network, and vice versa.
Access networks may utilize various technologies, such as copper wire, coaxial cable, fiber optic cables, wireless connections, or a combination of these. The choice of technology depends on factors like distance, bandwidth requirement, cost, and geographical considerations.
These networks provide the vital link that facilitates communication and connectivity for end users. They enable individuals and organizations to access the internet, make phone calls, watch television programs, and access other network-based services. Access networks also play a crucial role in extending the reach of network services to remote and underserved areas.
Overall, the access network acts as the bridge between end users and the wider network infrastructure, serving as the conduit that enables the flow of information and services from the service provider to the customer.
