Residential users and businesses can connect to the Internet in a variety of ways through Internet Service Providers (ISPs). The different methods of achieving this are called access technologies. While these technologies are traditionally based on wired technologies, wireless Internet connectivity is increasingly driving innovation based on access technology. Access technologies are generally divided into two categories which encompass a range of different access methods. Narrowband technologies refer to data download capabilities of up to 128 kbps and include dial-up connections, leased circuits using modems, split T1 data circuits, and integrated services digital networks ( ISDN). (Comer, 2009). Broadband technologies refer to technologies with higher download capacity. DSL and cable modems are considered broadband, along with wireless technologies and data circuits that are T1 or higher. The differences between technologies generally lie in the different ways each technology can use its local loop, that is, the connection between the ISP and the subscriber location. For narrowband technologies, the main Disadvantages are limitations in speed capabilities. The fastest of these is ISDN, which provides connectivity up to 128k over telephone lines using digital signals and twisted pair technology with two 64kps channels having the ability to combine and link. A third channel controls the connection. ISDN is twice as fast as dial-up technologies and provides a reliable, long-distance connection over the local loop. Krutzke says that for some low-speed applications, narrowband technologies provide a more reliable connection.
