Topic > Access Technologies: Connecting to the Internet

There are various ways that residential users and businesses can connect to the Internet through Internet Service Providers (ISPs). The various methods for doing this are called access technologies. While these technologies have traditionally relied on wired technologies, wireless Internet connectivity is increasingly driving access technology-based innovation. Access technologies are generally divided into two categories that include a range of different access methods. Narrowband technologies refer to data download capacities up to 128 kbps and include dial-up connections, leased circuits using modems, fractional T1 data circuits, and Integrated Services Digital Networks (ISDN). (Comer, 2009). Broadband technologies refer to technologies with higher download capabilities. DSL and cable modems are considered broadband along with wireless technologies and data circuits at T1 or higher. Differences in technologies generally lie in the different ways each technology can use its local loop, which is the connection between the ISP and the location of the subscriber. For narrowband technologies, the main disadvantages are limitations in speed capabilities. The fastest of which is ISDN, which provides up to 128k of connectivity over telephone lines using digital signals and twisted-pair technology with dual 64kps channels that have the ability to combine and link. A third channel controls the connection. ISDN is twice as fast as dial-up technologies and offers a reliable, long-distance capable connection over the local network. Krutzke says that for some low-speed applications, narrowband technologies offer a more reliable connection.
