How It Works

A Cable Modem is a digital modem that uses a coaxial cable connection. The same line as Cable TV, except filtered for the data. This data connection is received by a Cable Modem, which decodes the signal into your PC. This Internet cable traffic is typically filtered and separate from the rest of the Cable TV lines in your house.

Cable modem speeds vary, depending on the cable modem system and traffic load. In the downstream direction, network speeds can reach 27 Mbps, an aggregate amount of bandwidth that is shared by users. Few computers will be capable of connecting at such high speeds, so a more realistic number is 1 to 3 Mbps. In the upstream direction, speeds can be up to 10 Mbps. However, most modem producers have selected a more optimum speed between 500 Kbps and 2.5 Mbps. Some service providers limit upstream access speeds to 256 Kbps or less. An asymmetric cable modem scheme is most common. The downstream channel has a much higher bandwidth allocation (faster data rate) than the upstream, primarily because Internet applications tend to be asymmetric in nature. Mouse clicks and e-mail messages are not bandwidth intensive in the upstream direction. Image files and streaming media (audio and video) are very bandwidth intensive in the downstream direction.


How Is It Installed?

Your local cable company will have a couple of installation options available. Either a technician will come to your home and connect the cable to your new high speed modem, or you may be able to choose to do it yourself. Doing it yourself will involve a kit provided by the local cable service provider with everything needed to get the service up and running.

- Preparation

- Time Frame

Cable is usually connected more quickly (usually with a few days of placing the order) than DSL or a dedicated circuit, because cable does not have to provision service through the local exchange carrier (the phone company.)
