How does ADSL compare to cable modems?
ADSL gives you a private and secure connection over a single telephone line, while cable modems share their bandwidth with multiple users. This means that connection speeds for cable modems will vary according to the number of users who are using the same bandwidth. Cable modems are also limited to homes, which can support two-way cable modem transmissions, whereas ADSL is available to anyone with a phone line. Moreover, you will require additional new cabling to support cable modem, while ADSL can work on your existing phone line.
