What factors may affect broadband speed?

Submitted by isuru on Tue, 01/11/2022 - 11:51

The actual speed you experience may vary substantially from theoretical values depending on the following factors:

  • The 'line profile' that is operative on your service SLT places Broadband services on an initial line profile that defines the technical parameters for each package and constrains maximum download speeds, in order to achieve the highest possible connection stability. SLT Customer Support Team may then change to optimal speed based on the feedback of customers to explore the tradeoff between speed and connection stability that applies for their individual situation.
  • The length of copper wire from your premises to the exchange
  • The number and Type of other digital services being used by other customers over copper pairs within the same cable sheath.
  • The configuration and line quality of the copper wire between the exchange and your premises
  • Electrical interference from outside sources (such as electric motors)
  • The configuration of the copper wiring within your premises
  • The software configuration and application on your computer (in particular how it uses the uplink back to the exchange)
  • The capabilities of your ADSL modem or router
  • The capacity of, load on, and data access rate of the destination host computer which you are accessing

    So it is quite true that the factors listed above will reduce your speed from theoretical values. The following parameters may be useful in understanding the advertised bandwidth.

    • Bandwidth

    Bandwidth is the capacity of any broadband connection which determines the maximum amount of data it transports.

    In some situations subscribers would not be able to experience the maximum bandwidth as advertised in the package due to numerous technical reasons. In such situations maximum possible bandwidth would be provided to customers after conducting a technical evaluation test. However if the upper bandwidth exceeds the minimum permissible bandwidth which is referred to as the “minimum bandwidth”, the said package would not be issued to customers. Instead subscribers would be provided with another suitable package which supports his or hers line conditions.

    • Maximum & minimum bandwidth parameters
