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

Given this scenario, what kind of connection is it better 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 browse.



ADSL and VDSL connections

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

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

Connection identification

Before we start with the differences that may exist, you need to agree that both are, simply and simply, internet connections via a cable that allow for file uploading and downloading. thanks to the data transfer capacity they offer.

Differences between ADSL and VDSL

However, the similarities between the two types of connection can only reach the concept. Since performance and the way it works are noticeably different. Read on to learn more!

Asymmetry vs symmetry

The main difference between the two connections: the ADSL it is nothing of an asymmetric digital subscriber line. This means this type of connection cannot maintain 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 subscription line). Its very name shows that the difference is very well established, right?

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

What is the difference in speed due to?

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

On the other hand, VDSL has a total of 4 channels: 2 for upload and 2 for download, which is why there is a huge difference in the speed of each.

Distances between the control panel and the user

ISPs who use each of these connections try to do the best possible job for provide stable service to its customers.


In this sense, distance is not in itself a fundamental factor, as is the number of connections that exist along the path. In the case of ADSL connections, if the user is more than 6 km from the control panel, his internet service could be significantly affected, even more so if there are many connections that could reduce the power.

As for the VDSL connection, the problem is the same, as it is a connection in optical fiber that, while much more effective, not many companies have enough material to cover long distances, which is why (for now) it may not have achieved the expansion that was expected.


Which do you choose?

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

The disadvantage? It costs more, but if you have the resources, it will be a great long-term investment. Speed ​​and stability are guaranteed.
