Sometimes looking back opens your eyes to what awaits us in the future. If you look in the rear view mirror for internet use, you can see an incredibly fast development. A trend that is certain to continue and that places ever increasing demands on data throughput and bandwidth of the Internet connection. Together with Vodafone we show how you can prepare yourself for the future of the Internet.

Sometime in the Year 1995 the future began in Germany. Because this year ISDN was introduced nationwide in Germany. For the first time it was possible to make phone calls AND use the Internet at the same time. If both ISDN lines were usable for the Internet, you surfed with a maximum of 128 kbit / s. So it only took about 5 minutes to download a song.

Despite these modest data rates from today's perspective, ISDN enabled permanent and unrestricted use of the World Wide Web for the first time – and made an important contribution to the development of the Web as one of the central ones Elements of the economy and our everyday life.

With the introduction of ISDN, data consumption and the quality of Internet applications also increased. A development that continues to this day and will continue. But the DSL technology currently prevailing in Germany is already reaching its physical limits and is increasingly slowing down users.



Because data exchange over the fixed network grows and grows. During the year 2013 still approx. 20 Gigabytes of data per month and broadband connection were transmitted, it was 2019 beautiful 110 Gigabytes per month and broadband connection.



And the trend is unbroken, because more and more devices per household are connected to the Internet and more and more actively used Internet Services per person make our lives more enjoyable and exciting with video telephony, streaming, high-definition films or online gaming. However, all of them also bring with them a huge hunger for data.

With the long-serving DSL and the new Internet via cable fiber optics, two technologies are currently on the market that have to face the challenge of growing data hunger. We want to clarify which of the two Internet technologies is better positioned both today and in the future.

Cable fiber versus DSL: who is ahead?

The difference between the two technologies starts at the distribution box. Until then, both of them have an internet signal via cable fiber. The cable fiber is comparable to a data superhighway without a speed limit. In our analogy, the distribution box marks the departure and from there our signal takes different paths.

Because while DSL continues to travel towards our house or apartment connection due to the thin and not particularly well shielded telephone line, the cable uses fiber optic signal the thicker and better shielded coaxial cable of the cable TV connection.

And that has immense consequences for data speeds. Because while with DSL maximum 250 MBit / s reached in the download, delivers Cable fiber already 1 gigabit / s and therefore 10 – times faster internet.

Admittedly, from the perspective of Internet users in the year 1995 or even more 2010 both download rates are impressive, but 2020 is not just surfed on a computer in a household, but a number of devices with data-intensive applications access the Internet at the same time. Online gaming, video telephony and streaming often take place at the same time and require high stability as well as speed.

Here, too, cable fiber can shine due to the best shielded cable and stands out DSL in terms of data quality.

The internet of the future?

Nobody can say for sure how the Internet will develop. But looking back clearly helps if you want to make a basic forecast. Because while Internet companies and trends come and go, there is one thing that is constant: The growth of data exchange has increased year after year since the invention of the Internet.

With regard to our two technologies, we must therefore state that the development of DSL has ended and no significant increases in speed and stability can be expected here.

Cable-glass fiber, on the other hand, holds further development potential despite the current superiority. Only recently, the new DOCSIS 3.1 cable protocol created a new standard with which Vodafone can make even better use of the capacity of the cable fiber optic network and allow gigabit transmissions over many kilometers. In perspective, there are even download rates of 10 Gigabit / s possible.

Conclusion: Cables and fiber optics offer what DSL lacks

The solid DSL was able to serve the data demand for many years, but now technology is reaching its limits. With cable fiber optics, however, a technology is available that can already be used today without any construction effort up to 10 – times faster internet possible and offers further development potential.

Vodafone is currently 17 Millions Gigabit access ready. By 2022 the company wants to be almost entire cable network with 24 Trim millions of connections to gigabit speed – together with cable fiber optics it will even be 25 million. In the next few years, Vodafone will therefore be implementing more high-speed connections for German citizens and businesses than all other competitors combined.

The step into the future is very easy: Because Vodafone also offers the free exchange service and low tariffs also an award-winning WiFi router, making switching to cable fiber a breeze.
