ADSL vs. VDSL: What's the Difference?
Edited by Sumera Saeed || By Sawaira Riaz || Published on November 1, 2023
ADSL (Asymmetric Digital Subscriber Line) and VDSL (Very-high-bit-rate Digital Subscriber Line) are both DSL broadband technologies, with VDSL offering faster speeds but over shorter distances than ADSL.
Key Differences
ADSL and VDSL are both forms of DSL (Digital Subscriber Line) technologies. ADSL has been around longer and is more commonly found in households, especially in areas farther from a central office or node.

The primary distinction between ADSL and VDSL is speed and range. VDSL can deliver faster internet speeds, often up to several times faster than ADSL. This is particularly beneficial for data-heavy tasks like streaming in HD or online gaming.

While VDSL boasts higher speeds, it comes with a limitation in distance. VDSL connections are most effective over shorter distances, typically less than a mile from the central office. ADSL, on the other hand, can cover longer distances but with reduced speeds.
