An access network is a user network that connects subscribers to a particular service provider and, through the carrier network, to other networks such as the Internet.
Some types of access networks:
- Ethernet is the most commonly installed wired LAN (local area network) technology. Ethernet LAN typically uses coaxial cable or special grades of twisted pair wires.
- Wireless LANs allow mobile users to connect through a wireless (radio) connection.
- Fibre optic networks such as fiber to the home (FTTH) use optical fiber from a central point directly to individual buildings such as residences, apartment buildings and businesses.
- ADSL (Asymmetric Digital Subscriber Line) is a technology for transmitting digital information at a high bandwidth on existing phone lines to homes and businesses.
