Internet Access Options
Even if you weren’t around to hear it, you know what a dial-up internet connection sounds like. Movies and commercials are rife with jokes about the antiquated internet access technology. Most people have switched to a more updated connection and left it at that. But with separate service and data plans for your cell phone, home computer and mobile devices it may be time to cut back on the expenses and go back to basics-or take out a third mortgage.
This is the oldest and most widely used type of internet connection. It works by connecting a computer to an Internet service provider (ISP) using an analog modem and POTS (plain old telephone system). Even though cable and satellite internet have since expanded their coverage, dial-up still supports a large number of customers in remote regions. Dial-up service is inexpensive to set-up and maintain; and the existing POTS infrastructure is extensive, making internet access through dial-up widely available. However, the average speed is only 56 kbps. This makes dial-up too slow for certain activities such as online gaming and video streaming.
Digital Subscriber Line (DSL)
DSL internet uses the same physical network as a dial-up connection but produces speed from 256 kb to 24 mb per second.
T1 lines use existing POTS infrastructure as the framework for laying fiberoptic or copper cabling. This cable must be physically connected to a network router to create a connection making it an expensive service to obtain. However a t1 line may support data rates up to 1.544 megabits per second.
Cable connects consumers using a radio frequency signal similar to the over-the-air (radio-wave) method used in traditional television broadcasting. This signal is transmitted to the computer or web-enabled device physically, through fixed optical fibers or coaxial cables located on-site. Cable internet can be expensive as it requires the use of a transmitter near the subscriber; the subscriber essentially pays for the maintenance and upkeep of this tower.) Also this technology is not able to conquer the problem of “the last mile” providing access to individuals in remote locations.
