The whole point of my average speed argument is related to only & only Retail Wired segment.
You guys are taking Steam data for reference.. which is completely inaccurate.
Firstly, The total bandwidth in India in use (Lit) is 1.6Tbps (link ref1.46), this bandwidth is used for 3G,4G,2G wired line and WiMax Etc.. by various operators.
From what i know BSNL hs total capacity of 240Gbps, while MTNL has around 60Gbps Etc Etc for use which is also used for 3G/Wired/Wimax Etc.
Of all BSNL has just 150Gbps for wired broadband, MTNL has just 50Gbps, Airtel has around 120Gbps for wired subscribers. Finally ACT has around 170+Gbps in use for their customers.
The above figures beat my own estimations of ACT contributing to national average. As for any sources, You can file RTI to BSNL and MTNL and find out their present capacities and how much of bandwidth is in use for Wired segment (ADSL+FTTH).
