Difference between ADSL and Cable

Are you trying to decide which internet service provider (ISP) is best for you? There are a few factors you should consider, but one of the most important is the type of service. ADSL and cable are the two most common types of internet service, but what’s the difference between them? In this post, we’ll compare ADSL and cable and help you decide which one is right for you.

What is ADSL?

ADSL is a type of digital subscriber line technology, that offers a high-speed Internet connection over standard telephone lines. ADSL supports data rates of up to 8 Mbps downstream and 1 Mbps upstream. This is significantly faster than the speeds offered by traditional dial-up modems, which typically max out at 56 Kbps. In order to take advantage of ADSL service, you need to have a special ADSL modem, which is connected to a filter that splits the signal into two frequency bands: one for voice and one for data. The data signal is then sent to your computer via an Ethernet cable, while the voice signal remains on the telephone line.

What is Cable?

Cable internet services are a type of broadband internet that uses cables to deliver high-speed internet to users. Cable internet is typically faster than ADSL, and it can be more reliable because it is not affected by weather conditions. However, cable internet can be more expensive than ADSL, and it is not available in all areas. In addition, cable internet requires a cable modem, which must be connected to a cable jack in order to receive service.

Difference between ADSL and Cable

  • ADSL and Cable are two types of digital subscriber line (DSL) broadband internet services. They both use copper wire telephone lines to deliver high-speed internet to customers. The main difference between ADSL and Cable is that ADSL uses the existing phone line while Cable uses a dedicated cable TV line.
  • ADSL is cheaper than cable because it uses the existing phone line. It is also available in more areas than cable because it uses the existing phone network infrastructure. However, ADSL speeds are slower than cable because the phone line is shared with voice traffic.
  • Cable is more expensive than ADSL because it requires a dedicated cable TV line. However, it is available in fewer areas than ADSL because there must be a cable TV network infrastructure in place. Cable speeds are faster than ADSL because the cable TV line is not shared with voice traffic.
  • ADSL is best for users who want a cheaper option and are not concerned about speed. Cable is best for users who are willing to pay more for faster service.


ADSL and cable are both great options for internet service, but they do have some differences. Cable tends to be a bit faster than ADSL, and it can also handle more devices at the same time. However, ADSL is often less expensive than cable. If you’re looking for the best possible service, the cable may be the way to go, but if you want to save money, ADSL could be a better option for you.
