What are the differences between VDSL and ADSL and which is faster?

The internet has become one of the essential tools within society in recent times. The type of connection varies according to user demand, as well as the tools that companies have to offer a good service.

Given this scenario, what type of connection is best for your desktop or laptop? This time you will be able to delve a little deeper into the world of internet connections and find out which element will allow you faster access to navigate.

ADSL and VDSL connections

When it comes to connections, these are one of the most used in the world. While there is a practically abysmal difference in performance, the economic part is always something to consider.

Throughout this article, you will get much more information about ADSL and VDSL connections: advantages, differences and everything you need to draw your own conclusions about which is better, faster and ideal for your pocket .

Identifying connection

Before starting with the differences that may exist, it is necessary to agree that both are, simply and simply, internet connections through a cable that allow the uploading and downloading of files thanks to the data transfer capacity they offer .

Differences between ADSL and VDSL

However, the similarities between both types of connection can only reach the concept. Since the performance and the way they work are considerably different . Read on to learn more!

Asymmetry vs Symmetry

The main difference between the two connections: the ADSL is nothing an asymmetric digital subscriber line. This means that this type of connection is not capable of maintaining parity between download and upload speeds .

Which is greater? Well, for this type of connection, the download capacity can be 8 Mbps, while the upload speed is 1.3 Mbps.

On the other hand, VDSL (or high-speed digital subscriber line). Its very name shows that the difference is very well established, right?

This type of connection stands out for being very fast and for its versatility , offering an asymmetry of 20 Mbit / s download and 5 Mbit / s upload or a symmetry of 20 Mbit / s for upload and download.

What is the difference in speed?

The distance that one type of connection marks over the other has much to do with the number of channels that each one uses . On the one hand, the ADSL uses only 2: the upload (corresponding to user-network) and the download (corresponding to network-user).

On the other hand, VDSL has a total of 4 channels: 2 for uploading and 2 for downloading, so that is why the abysmal difference in the speed of each arises.

Distances between the control panel and the user

The ISPs that use each of these connections try to do the best possible job of providing stable service to their customers .

In this sense, distance is not a fundamental factor by itself, so is the number of connections that exist along the way . In the case of ADSL connections, if the user is more than 6 km away from the central, their internet service could be considerably affected, and more if there are many connections that can reduce power.

Regarding the VDSL connection, the problem is the same, as it is fiber optic connection that, although it is much more effective, not many companies have enough material to cover long distances, a reason why (for now), perhaps it has not reached the expansion that it was expected to have.

Which one do you choose?

ADSL and VDSL connections are very good and the definition of the best one will depend on your needs . In terms of speed, the VDSL connection is a huge favorite.

The disadvantage? It has a higher cost, but if you have the resources, it will be an excellent long-term investment. Speed ​​and stability are guaranteed.
