TRAI To Decide On Minimum Download Speed For Internet On Mobile
As of today, there's no official binding regulation on the telecom service providers to deliver Internet at any minimum speed; and that's why your download speeds can go down to just a few KBps while you're expecting 7.1 Mbps or 21 Mbps as promised by the companies in their advertisements.
We do not have any information about what speed is TRAI going to decide as threshold, but it's likely to be the broadband speed aka 512 Kbps. While this is still very low; the 3G and CDMA-EVDO service should be able to provide about 1Mbps speed with 95% success rate. On the 2G connections, however - the minimum speed is expected to be about 5.6 Kbps.
TRAI is seeking public opinion till May 5 and will accept counter comments by May 12. Check out the official PR from TRAI in the source link below.
