DSL vs. VDSL: The transmission rate
The first difference is in the possible transmission rate. In the case of a conventional DSL connection has a transfer rate of up to 16.000 kbit/s (16 Mbit/s) is possible, while, in contrast, VDSL bandwidths of up to 100,000 kbit/s (100 Mbit/s) permits. As a result, only higher Download Rates do not arise; also, the Upload of data can be done in the case of VDSL is faster.
DSL vs. VDSL: I watch TV
Some Internet providers, such as Telekom or Vodafone, offer a service called IP TV. Here are the TV signals are received via antenna or satellite, but via the Internet line. The transmission rate of the DSL would be too weak. In the case of VDSL, however, in the case of a corresponding transmission rate, it also HD can be used to receive content via the Internet line. VDSL also offers the technical prerequisites for other demanding Internet applications.
DSL vs. VDSL: The technology
DSL is transmitted over copper cable. By various physical aspects of the disadvantages here. Simply put: In the case of copper cables, the signal quality and thus also the transmission is getting worse every Meter rate. In the case of VDSL, however, a new type of transmission medium is used: fiber-optic cable. Although there is a signal drop, however, this is in contrast to the copper cables is very low. While in the case of copper cables to a physical transmission medium is glass fibers, an optical transmission medium.
DSL, or VDSL?
VDSL DSL is clearly superior, as it rates both higher Transmission as well as a future-proof technology. Unfortunately, VDSL is not yet available everywhere. If you play with the thoughts to switch from DSL to VDSL, talk to your Internet Provider - this can give you more information about whether VDSL is available, or whether it will be available in the near future.
