The download speeds that customers get in Chennai, Colombo and Dhaka are not very different, if you carefully examine the results of the October 2009 results of broadband QOSe using the Ashokatissa methodology jointly developed by IIT Madras and LIRNEasia. What differs is the level of truth in advertising. In Sri Lanka, everybody is lying. In India, they are closer to the truth.
The difference is regulation. In India, the regulator is proactive on this issue; in Sri Lanka, the regulator only worries about things like porn and imaginary towers. We cannot mandate truth in advertising; only engage in friendly moral suasion. In other words, we will try to shame the operators into calling their products by the right names: 512 Kbps instead of 2Mbps would be a start?
