Differences in High Speed Internet Access

Broadband Internet access, also known as "high-speed Internet," has a high rate of data transmission. High-speed generally refers to any connection of 256 kbit/s (0.256 Mbit/s) or greater. Utilizing everything from telephone lines to satellites, differentiating between the various connection types can prove daunting. Basic information can eliminate the confusion.

Cable

Cable Internet service is provided via the same cable used to watch television. With some of the fastest download speeds available, cable Internet is offered by most major cable companies. Roughly 70 times faster than 56K dial-up, cable bandwidth is shared with others online. That said, shared bandwidth can thus somewhat slow connection speed. Choice of cable Internet providers is limited to the existing cable television provider in a geographical area. In 2009, monthly costs for a combination of cable television and Internet service range from $50 to $100.

DSL

Digital subscriber line (DSL) is a high-speed connection using the same wires as your regular telephone line. Shared lines do not interfere when using the Internet and telephone at the same time. Using DSL, information is sent faster than it is received. Signals become weaker as you get further away from the central office. Average monthly cost of service is $29.95. This service is not available everywhere.

Wi-Fi

Wireless Fidelity, or Wi-Fi, uses radio waves to provide wireless high-speed Internet connections. Physically wired connections from the user's computer to a modem are not required. All Wi-Fi stations utilize access points. An access point broadcasts a wireless signal, usually up to 100 to 300 feet. Computers detect the signal and connect to it. Computers and electronic devices must be equipped with a wireless network adapter. Installation of the adapter (router) costs about $50. Monthly service charges average $60.

WiMAX

Worldwide Interoperability for Microwave Access (WiMAX) provides wireless digital transmission communication, or transfer of data. Fixed stations provide WiMAX broadband wireless access up to 30 miles. Mobile stations reach anywhere from 3 to 10 miles. Many cities find WiMAX technologies cost effective and use WiMAX to connect to traffic lights and cameras. Home computers must have a WiMAX connection. The pricing scheme for this new technology, which is not yet widely available, is still being worked out.

Satellite

More expensive than cable or DSL, satellite provides a realistic high-speed alternative to those living outside cable or DSL provider areas. Start-up and installation costs for satellite service can range from $300 to $600. Monthly bandwidth costs range from $50 to $120 depending on location and provider.
