Broadband

The download speeds recorded by the TRCSL during the month of February has shown a mixture of results in both fixed and mobile broadband services. These tests were conducted in remote locations except for the fixed broadband services which were conducted at the Broadband Monitoring Unit (BMU) at TRCSL. The mobile broadband services based on HSPA technology were tested in five remote locations within a Colombo city.


A comparison shows an overall improvement in broadband speeds. However some of the tests which were conducted in remote areas have shown a different picture. In these locations download speeds of mobile broadband has been dropped to an unacceptable level which is far below the speeds advertised by the operators. A network infrastructure, inadequate to meet the demand is clearly the reason for this unacceptable situation. Since these tests were carried out under “ideal condition” other major factors which would affect the download speeds i.e. distance to the tower, weather condition and line of sight could be easily discounted.

The other technical factors inherent in HSPA technology which affect the final result were considered.

In terms of international best practices the mobile broadband based on 3G would not be an ideal replacement or a substitute over other broadband technologies. However the affordability and convenience in HSPA broadband has been able to change this situation in Sri Lanka. Today the majority of subscribers, particularly in Sri Lanka, would prefer to use HSPA broadband simply because of many advantageous it offers to the user. This trend is a challenging task for 3G broadband operators. The test results have clearly shown this condition in many test locations. The speeds have dropped below the level of 1Mbps (red line) and even reaches the values as low as 100kbps in many occasions. The 10MB file downloading process has shown that this speed drop is not an issue affecting that instance in the network. 

Advertising speeds of technology in headline lettering is useless unless we provide a proper service to the end users to facilitate their needs. In the effort of introducing a proper regime, the speed of 1Mbps would be an acceptable average in the first instance to be maintained in mobile broadband services. In a service with 3.6Mbps advertised speed, 1Mbps is about 28% from the total bandwidth. This value is significantly lower than the proposed standard which would be mandated for fixed services in the future.
The monitoring results and data recorded during the tests conducted by the TRCSL would be useful in the process of introducing a regime for mobile broadband in the future. 

The graphs which represent the speeds of fixed services have also been revised to facilitate the determination of future standards of broadband service. The expected average speed for unlimited fixed broadband services (Green line) has been brought to 60% level while the red line remains unchanged at the level 50% from the advertised bandwidth. These thresholds will be revised in the future depending on the aspirations.

A setting up a minimum standard for broadband download speeds would not only serves the customer better but also helps the broadband proliferation in Sri Lanka.
