This broadband performance test system (the "System") is commissioned by the Office of the Communications Authority ("OFCA") and designed, established, operated and supported by Hong Kong Internet eXchange ("HKIX").

The System enables broadband service users to measure the performance of their broadband connections as follows:

Download speed refers to the speed for downloading data from the System to the user device.

Upload speed refers to the speed for uploading data from the user device to the System.

Network latency refers to the round-trip time taken to transmit data from the user device to the System and subsequently for the user device to receive the data from the System .

Packet loss refers to the percentage of packets lost during the sending of the data from the user device to the System.

Jitter refers to the variation in the delay of received packets. At the sending end, packets are sent in a continuous stream with the packets spaced evenly apart. Due to network congestion and other factors, the delay between each packet may vary instead of remaining constant when received.

The System is designed to handle performance tests within the territory of Hong Kong .

The System is available for use free of charge to the users, but users should be mindful that their broadband service providers (BSP) may charge them for the use of the broadband services to access the website. Users situated outside the territory of Hong Kong (irrespective of whether they are subscribers to the service of local BSP) should bear in mind that they may need to shoulder additional service charges for accessing the System and the charges payable may be quite substantial.

To perform the test, users should choose one of the two options provided in this website according to the speeds of their broadband connections. The "Broadband Test – Below 100Mbps" option should be used to measure broadband connections under 100Mbps. The "Broadband Test – 100Mbps to 300Mbps" option should be used to measure broadband connections of 100Mbps or above and is optimised for measurement up to 300Mbps.

 

Users with iPhones and Android Phones

Apart from users with desktop and notebook computers, users of Apple iPhones and Android Phones may also gain access to the System. The relevant application software is officially known as "OFCA Broadband Performance Test" and may be downloaded for free through the following channels:

Apple iPhone: iTunes App Store

Android Phone: Google Play

Users should note that the System only supports measurements of upload speed, download speed and network latency for Apple iPhones and Android Phones.

 

Data Usage in Mobile Application Software

The data usage for the use of this system varies with the speed of mobile broadband connection under test. For tests on 4G connections, the data usage of a test can be up to 100 MBytes. Users are advised to keep track of their data usage from time to time in order to avoid any unnecessary mobile bill charges.

 

Factors Affecting the Results of the Measurement

The speed measured with the System may be lower than those claimed and provided by BSP in their service plans ("claimed speed") due to various factors including, but not limited to:

 

Data speed required for different applications

Data speed refers to how fast data is transmitted to/from our equipment or device. It is usually measured in units of megabit per second (Mbps) or kilobit per second (kbps). 1 Mbps equals 1000 kbps. Downloading a song of 4 MB requires less than 40 seconds if the data speed is 1 Mbps. The same song requires a much longer time of five minutes to download if the data speed is 128 kbps, the typical speed for 2.5 G (i.e. 2.5 Generation) service.

The following table lists the required data speed for different applications:

Applications Required data speed*
Listening to an on-line Internet radio program or on-line music 128kbps or above
Streaming of a low definition video 300kbps or above
Streaming of a high definition video 1Mbps or above
Using on-line texting, social networking websites, sending/receiving e-mails, browsing web pages Non real-time applications do not have a serious consideration in speed. Depending on the size of transmitting information, the time required will be different. With higher data speed, it will require less transmission time.

*Actual speed required depends on the quality of streaming media

 

Privacy Policy Statement

The Office of the Communications Authority ("OFCA") is concerned to ensure that all data submitted through OFCA Broadband Performance Test website (“the website”) are handled in accordance with the relevant provisions of the Personal Data (Privacy) Ordinance.

OFCA will record test results through the website without collecting any personal identifiable information of users. Such test records are collected for the compilation of statistical reports and the diagnosis of problems with or concerning computer systems to help improving the website.

 

Personal Information Collection Statement

When you perform test through the website, system will collect and record data obtained from the test result, including upload and download speed, network latency, connection type, device type and IP address. This information will be used by us only for preparing statistics. The website will not collect any personally identifiable information.

The data collected by the website are secured and access to them is restricted to authorised personnel only.
