The broader plan is to reach a minimum download speed of 2 Mbps by 2015. But for now, the Telecommunication Regulatory Authority of India (TRAI) has upped the minimum download speed from 256 Kbps to 512 Kbps (article available here). They have also re-defined this metric in the amendment to the regulation;
a data connection that is able to support interactive services including internet access and has the capability of minimum download speed of 512kbps to an individual subscriber from the point of presence (POP) of the service provider intending to provide broadband service
LIRNEasia’s most recent report on broadband quality of service experience diagnostics illustrates the actual speed achieved as a percentage of the advertised. All three fixed broadband plans tested in Delhi, Bangalore and Chennai under-perform consistently. The mobile broadband plans, including Airtel’s LTE, performs much worse. Using our research to inform policy, LIRNEasia responded to TRAI during a public consultation held in May, specifically on setting minimum download speeds for wireless broadband services.
