What is ADSL? Here’s the Answer

ADSL is an abbreviation of the name Asymmetric Digital Subscriber Line.

ADSL is a technology that will offer faster connection speeds than the traditional Internet through dial-up telephone lines could offer. ADSL is the technology that drives many Internet connections worldwide.

Although the new fiber technology allows faster connection to the Internet, ADSL is still a popular choice because of its flexibility. Fiber is connected to blocks or multi-dwelling houses ever since, but ADSL allows the individual customer to decide for themselves when the technology uses existing metal cables into the home or the business premises.

Within ADSL

Today, when we have constant access to high-speed Wi-Fi, it can be difficult to look back and imagine what it was like to use the internet in the past. We who used the internet during the nineties can still hear the sound: “kading-kading-kading-brrrrrr-pling” when connecting your computer to the internet.

When the internet had its break among the large masses sometime in the mid-1990s, households connected to the web via dial-up modems. These modems blocked the entire capacity of the telephone line and made it impossible to make phone calls while surfing. In addition, the traffic never came up at any impressive speeds, although some technology development took place. An image was uploaded in a few minutes and websites were made up of background color and text.

ADSL is introduced

When we look back on the internet’s childhood today, it is difficult to understand how it could even be popular before ADSL came with modems and routers that provided completely new possibilities and speeds. It was at the end of the nineties that ADSL made its entry. All of a sudden, the little flashing plastic boxes stood at the home of almost every company.

What came to replace the dial-up modems was the ADSL technology entrance. ADSL also uses the telephone lines for traffic in itself but does so at such a high frequency that there is plenty of capacity for telephone calls. In addition, an ADSL modem could deliver much higher speeds than its predecessors.

  • ADSL uses a higher frequency of the line than the fixed telephony
  • ADSL is a further development of the predecessor DSL
  • Modern ADSL solutions can deliver incredible speeds compared to dial-up modems
  • The letter A in the abbreviation ADSL stands for “Asymmetric”
  • The ADSL technology was initially developed to be able to transmit video to order via the telecommunications network
  • The majority of all broadband connections use the ADSL technology today but are increasingly challenged by fiber optics
  • The maximum speed of a connection depends on the distance to the nearest switching station
  • Technology with width and timing

If you interpret the whole abbreviation you get the “Asymmetric Digital Subscriber Line”, and with a little knowledge,  you hear that ADSL does not seem to be restricted to use in the telecommunications network. But the technology was launched at the same time as the phone jacket was left empty for the benefit of the mobile.

In theory, all-metal wires that come into the house can be used by ADSL. But it is so far more common to have the broadband delivered through the telephone jack instead of the electrical outlet or the hole for cable TV in the wall. However, no variant excludes any other: ADSL through the telephone jack can be spread through the house’s mains for better reception in the two-story villa.

Although they can be used with other broadband solutions as well, it is precisely around ADSL that a lot of smart accessories have been invented. So-called access points and switches are good examples of easy-to-use and smart solutions for expanding and improving a company’s network.

What is the future of ADSL?

The alternative that would reasonably cause customers to leave their ADSL broadband is the allure of super-fast fiber (which is now being expanded in every large and medium-sized city in the country) 5G and other future technologies also play a role here. At the same time, many people seem to think that the speed is fully satisfactory in the home, with maybe two connected phones a computer and a smart TV in HD.

Another fact that may be even clearer for ADSL technology’s continued survival is its flexibility. While fiber-optic networks are connected to entire properties, or even blocks, at a time, ADSL is something that the individual himself decides. Should two or more neighbors still want to share the connection, it is easily done with the right router.

Wireless ADSL routers/modems with powerful signals that supply both the large villa or the entire office with fast Wi-Fi, there is plenty on the market at reasonable prices. Many new models transmit more frequencies than their predecessors, which minimizes signal interruptions due to increased ether space. So it looks bright for ADSL in the future.

Problems installing ADSL

When ADSL is installed on a regular old telephone line, problems may arise because DSL is within a frequency band that can interact negatively with existing equipment connected to the same line.

It can, therefore, help with a frequency fillet in the premises to avoid interference between voice services, DSL and other connections to the line such as burglar alarms. This way, you get a more reliable ADSL connection and the telephony is not interrupted.
