Teleworkers typically use diverse applications (for example, e-mail, web-based applications, mission-critical applications, real-time collaboration, voice, video, and videoconferencing) that require a high-bandwidth connection. The choice of access network technology and the need to ensure suitable bandwidth are the first considerations to address when connecting teleworkers. Residential cable, DSL and broadband wireless are three options that provide high bandwidth to teleworkers. The low bandwidth provided by a dialup modem connection is usually not sufficient, although it is useful for mobile access while traveling. A modem dialup connection should only be considered when other options are unavailable. Teleworkers require a connection to an ISP to access the Internet. ISPs offer various connection options. The main connection methods used by home and small business users are: Dialup access - An inexpensive option that uses any phone line and a modem. To connect to the ISP, a user calls the ISP access phone number. Dialup is the slowest connection option, and is typically used by mobile workers in areas where higher speed connection options are not available. DSL - Typically more expensive than dialup, but provides a faster connection. DSL also uses telephone lines, but unlike dialup access, DSL provides a continuous connection to the Internet. DSL uses a special high-speed modem that separates the DSL signal from the telephone signal and provides an Ethernet connection to a host computer or LAN. Cable modem - Offered by cable television service providers. The Internet signal is carried on the same coaxial cable that delivers cable television. A special cable modem separates the Internet signal from the other signals carried on the cable and provides an Ethernet connection to a host computer or LAN. Satellite - Offered by satellite service providers. The computer connects through Ethernet to a satellite modem that transmits radio signals to the nearest point of presence (POP) within the satellite network.
