Typical Broadband Speeds Measurement and Methodologies for Fixed Access (Dated: 1 Jan 2015)

Fibre Broadband Typical Download Speed Range

Theoretical Speed (Mbps) Typical Speed Range* (Mbps)
100 96.1 – 99.5
200 191.6 – 199.1
300 291.0 – 298.9
GamePRO 300 296.6 – 316.2
1Gbps 655.4 – 772.8

* The Typical Speed Range refers to the range of download speeds that users can experience 80% of the time based on the specific test conditions and parameters stipulated below.

Testing Time frame: Oct to Dec 2014.

Measurement and Computation Methodologies for Fixed Access

  1. Test Equipment and Computers used

    Fibre Broadband

    Optical Network Terminal (ONT) used
    • Huawei HG8240

    The computers used

    Computer 1 Computer 2
    • Intel Core i5

    • Windows 7

    • Intel Core i5

    • Windows 7


  2. Sample Size and Methodology

    A total of 720 data points were collected over a period of 24 hours for each speed plan.

    The computers used for testing were connected to the ONT via a LAN cable. Every hour, downloads from all the sites listed below were initiated and the process was repeated for 24 hours so that both peak and off-peak hours were covered.

  3. Location of Test

    These data points were collected at different locations to provide geographical spread.

  4. Websites and size of file transfer

    The download throughput was assessed based on a balanced mix of local and international servers/websites (Singapore, Japan, Hong Kong, USA) with size of file transfer ranging from 100Mb – 1000MB.

  5. Computation of typical speed

    Typical download speed range for the respective plans were derived by taking the result at the 10th and 90th percentile of the speed distribution from the data points collected. Therefore this will represent the typical speed range that users can experience 80% of the time based on the above test conditions and parameters stipulated.

  6. Explanation of factors affecting Fibre Broadband speeds

    Many factors affect the download speed and delivery of internet traffic. Some of these are:

    • The broadband device/equipment used
    • The load on the local/international websites (the number of other people online & network associated traffic)
    • Your computer network configurations and software you're running, such as Outlook or Internet Explorer
    • Your type of internet connection (wired LAN/ Wireless connection)
    • The number of people your broadband connection is shared with
    • Viruses, spy-wares and file-sharing software
