Advantages And Disadvantages Of DSL Broadband Connection!

With the increased use of the internet, the service providers have also increased, claiming that their services will be faster. With attractive advertisements, new ranges of offerings are coming up. Before opting for a particular ISP, you need to know the different kinds of ISP and the advantages and disadvantages of DSL broadband. SKY Broadband is a broadband service offered by Sky UK in the United Kingdom

Broadband is a broader term used for different types of internet connections, such as cable, satellite, fiber, and DSL. Based on the requirement, preferences, and place of living, you can choose. 

What is DSL Broadband?

Digital Subscriber Line (DSL) is the technology through which digital data is transmitted via an existing telephone network. Operating over telephone lines, DSL can deliver data up to a speed of 25 Mbps. Besides reliability, you should have a Speedier IT application in today’s competitive market.

DSL service can be simultaneously delivered with a telephone service wired on the same telephone line because DSL uses higher frequency bands per data. The bit rate of DSL Services ranges from 256 kits to 100Mbit/s 

There are two types of DSL Connection: ADSL or Asymmetric and Symmetric or SDS. ADSL is a cheaper and faster download speed than uploading. But rates for both downloading and uploading are the same for downloading and uploading. This is particularly helpful for professionals who need to backup more data regularly.

Asymmetric DSL divides the available frequencies in a line presuming that most internet users look at downloading more information than what they upload or send. ADSL is distance sensitivity technology. For addressing the distance limitations of DSL, many technologies are used, such as the below:

  • SDSL (Systematic DSL)
  • RADSL (rate-adaptive DSL
  • IDSL (Integrated Services Digital Network
  • Uni-DSL (Universal DLS)

DSL is a medium for providing internet access by transmitting digital data through a phone line. Both phone and internet are used simultaneously. They find use in small businesses and residences where it becomes easier to access both.

You can connect to the internet via Local Area Network (LAN); the cable modem can also do it. Many factors can affect the bit rate, such as the DSL technology, line condition, and service-level implementation.


1: Capacity Utilization

The copper wires of the telephone lines can handle much bandwidth or range of frequencies than that required for VOICE. DSL exploits this capacity for carrying information on the wire without disturbing the capability to have a conversation. Thus particular frequencies are matched to specific tasks. It thus ensures optimum utilization of resources.

2: Speed & Connection

DSL handles a large amount of data, and the speed for other data applications is more. The chances of getting congested are the least because DSL is used either for small businesses or residential purposes. The events of others using the telephone line could be mutually agreed upon. The volumes of data to be handled are not too large. The bit rate is also not likely to reduce, and the speed is ensured. Unlike cable broadband, there is least sharing of connection

3: Guaranteed Bandwidth

While you share a broadband connection with other users, it may be difficult to calculate the amount of bandwidth you need to run your current and future operations. These are critical to your business. But if you are using a DSL connection, you are assured of the bandwidth you would need to maintain the productivity of your business. Moreover, there is no interference of one application with the other. Being assured of the bandwidth, you can allocate a definite amount of bandwidth for each business application…

4: Reliability

When you work with DSL, you are dealing with only one service provider without the involvement of any third party. You can always rely upon a man you have chosen directly who will be more reliable and loyal. 

5: Security

Since using DSL does not require sharing connections with others, you are at the top of the security aspect. Deployment of security applications becomes simple and authentic services can be provided quickly. The overall security of the network becomes easy.

6: Minimal Downtime

Compared to a shared connection, you will have experience of minimum downtime. As a result, you fully utilize your time and monitor and control the business issues more efficiently.

7: Cost

It is like killing two birds with one arrow. But connection cost is more than a shared connection. For using DSL, you need to pay a flat rate. But for the shared link, you have to bear associated fees for making individual use.

8: Minimum Latency

Latency is the time taken for the DSL Connection. By choosing customized connectivity, you can have minimum latency.


1: Distance

People have to be close to the server or the network to enjoy a speedy connection. But, distance is a significant constraint in this regard. If the distance is more, either DSL will not be available, or the cost of having it will be more.

2: Imposed Phone

You get the phone line only when you have a dedicated landline. In these days of mobile phones, availing of a phone line becomes taxing and cumbersome. Whether you need it or not, you have to avail the phone compulsorily.

3: Proximity to the DSL Distribution Point

The nearer you are to the main distribution point of DSL better speed you will get. If you are not closer to the main point, you are disadvantaged in rate. It is because of the speed that you are investing in DSL. 

4: Customized Modem 

When the service providers connect DSL, they insist that you go in for their modems. Consequently, you may have to pay more. On the contrary, there may be a clash of interests, and the service provider may not attend to your work correctly.

5: Competition with Cable 

Cables and DSL are technologically rivals to each other. While the signal strengths of cables don’t weaken, even after being stretched for long distances, DSL with length provides less speed and becomes weaker too.
