What is high speed internet access

DSL speed

High-speed Internet does not mean fast Internet for everyone - Find out what the term is here and whether you get the bandwidth paid for.

What does high-speed DSL mean?

The term high-speed DSL or high-speed Internet is becoming more and more common. But the term is broad. There is no clear definition of when an Internet connection can be described as high-speed. In the past, ISDN access with a bandwidth of 128 Kbit / s was called high-speed Internet. But this download speed can hardly be called high speed anymore. When the term high-speed internet is used, it usually means broadband connections to the internet. There are different definitions of the bandwidth from which high-speed DSL can be used. You should, however, assume a download speed of at least 1 Mbit / s. However, DSL is not the only variant of high-speed Internet.

How do I get access to the high-speed internet?

It is now possible to surf the Internet at high speed via the TV cable network. This is often referred to as cable internet. Satellite connections are another option for high-speed access. These enable high-speed internet via the satellite systems. Wireless high-speed access is currently also possible with cellular technologies such as UMTS or LTE (link to https://www.wieistmeineip.de/ratgeber/internet/mobiles-internet/). If you take a closer look at the variants presented, it becomes clear that the value of 1 Mbit / s for the designation of high-speed Internet is set very low. Nowadays, all variants promise up to 200 Mbit / s. But they have their advantages and disadvantages, so that high-speed access can rarely be implemented at such speeds.

What does upload and download speed mean?

Upload means “upload”, download means “download” accordingly. The respective speed describes how long it takes to upload a certain amount of data to a server or to download it from there. The unit of measurement used is usually megabits per second (Mbit / s or Mbps). Providers of DSL and other bandwidths advertise with information on upload and download speeds, for example "surfing at up to 100 Mbit / s". But what actually is a normal or good speed? Basically, you should know that the number given in advertisements actually always refers to the maximum download speed. As a user, you can usually download data much faster than uploading data to a file server yourself, for example. The upload speed is often only 15 - 20% of the maximum download speed; with extremely fast connections via fiber optics, 50% of the maximum speed can sometimes be achieved. Only with so-called SDSL is data downloaded and uploaded at the same speed. However, there are hardly any tariffs of this type for private customers.

What speeds does a typical DSL connection achieve?

The "average DSL connection" has a download rate of 16 Mbit / s, which is usually completely sufficient for surfing and streaming. Good or fast connections via VDSL or fiber optic can easily reach 100 Mbit / s and more in downloads. In the upload, 20 Mbit / s is a normal or average value - the upper limit is currently 40 - 50 Mbit / s. To get a feeling for what these values ​​mean, an example helps: A 90-minute film in medium quality is approximately one gigabyte in size. If you want to download it with a 100 Mbit / s connection, it takes a little over a minute. An upload at 20 Mbit / s takes more than six minutes for the same file. Since in reality the actual upload and download speed also depends on other factors, it can be useful to regularly carry out a speed test in order to find out what actual speeds you get when surfing.

In the download calculator you can calculate how long individual downloads would take with your connection.
