DSL – Its Advantages and Disadvantages

Before a business or homeowner considers purchasing a DSL broadband service, they must understand what DSL (digital subscriber line) can offer them as well as its advantages and disadvantages.

In todays world there are a variety of ways to connect to the Internet. These include using a modem, a local-area network connection in your office, a cable modem or a DSL broadband connection. DSL offers a high-speed connection while using the same wires as a phone line. DSL speeds are available in a range from 144 Kbps to 1.5Mbps. This is 2.5 to 25 times faster than a standard 56Kbps dial-up modem. DSL broadband is useful for sending bandwidth-intensive applications like streaming audio/video, video conferencing, telephone calling, application programs, online games and other high-bandwidth services.

The following are some advantages of DSL service:

  • Broadband Internet and Phone at the same time: You can be online on facebook and twitter and at the same time talk to your friend on your landline connection. This was not possible with dial- up connection as going online meant you could not use your landline phone.
  • Faster Internet: the main USP of DSL is that it offers broadband speed internet. It is was faster than the 52 kbps dial up connection. DSL internet provides speed of above 2mbps


  • No wiring: Since DSL broadband connection uses phone line to connect to the net no special wiring is required. It saves you the hassles of getting the wiring done and also makes your home look more presentable with less wiring.


  • No Dropped Connections: A major problem with dial up connection was that it would disconnect all of a sudden leaving you high and dry. DSL connections do not have these problems and seldom is there a disconnection.


  • Faster Downloads: Faster DSL network means, that downloads are faster. Now you can download more files in the same time.
  • Multiple Computers on Single DSL Line: More computers can be connected to internet using the same DSL connection. That means no need to take special connection for an extra computer or laptop.

One thing to remember when signing up for DSL, the modem is usually supplied by the DSLprovider as part of the installation.

The following are some disadvantages of DSL:

  • Your DSL connection works faster if you live closer to the provider’s central office. The farther your home is from the ISP’s office the more your speed will reduce. This the reason that ISP’s use the word up to while specifying speeds.


  • Data being received is faster than data being sent over the Internet.


  • DSL availability is limited to certain cities, not everyone can get this service

It’s important to weigh the advantages and disadvantages of using a DSL connection. Having adequate bandwidth can be key to a business’s success and vital to a homeowner working out of the home. Both types of consumers can’t afford downtime due to a sub-par internet connection. DSL can be just the internet service they are needing, or it could be that they need more bandwidth to satisfy their needs.
