What is ADSL?


ADSL is a relatively new technology that stands for Asymmetric Digital Subscriber Line. ADSL is more commonly known as just DSL. It can provide a very fast transmission of video and voice to homes over ordinary copper telephone wires. It requires a special DSL modem to function.

ADSL modems transmit faster than conventional modems. They are generally designed to be the most cost-effective way to provide high-speed Internet access to areas with low market penetration of high-speed cable Internet access. Thus, it is its primary competition.

Differences between DLS types

Unlike other forms of DSL, ADSL has an asymmetric high-speed data flow, meaning that it can process data flow at high speeds in only one direction. Providers market ADSL as a way to access the Internet and download at very fast speeds without needing to run servers that would require bandwidth in the other direction.

Technical Statistics

While a conventional dial-up modem can only download up to 56 kbps per second, the ADSL modem can download at the rate of 256 kbps and can typically go as fast as eight mbps. While the download speeds are very high, the upload speed of the ADSL is comparable to dial-up modems. The ADSL starting upload speed is around 64 kbps and can typically go as fast as 256 kbps. Your upload and download speeds will depend on your distance from the provider?s central office or remote terminal.

The ADSL is relatively slower than today?s cable modem when it comes to both download and upload speeds. However, cable modem connection is sometimes limited to certain areas and not available in smaller markets. In these places, if people want to have high speed Internet they have no choice but to use ADSL. Typically, you can get more information on ADSL and ADSL servers online.
